3D Printing Nerd LIVE from RAPID + TCT 2022!

because i can see it up here once it goes live i think i think in stream there we go i think we're live we are we're alive just waiting for it to show up on the ipad there we go let's see if we're going to do that there we go how do we look how do we look got the notifications people hear me can you see me there we go high five sweet i always wait for rc maniac to let me know if you can hear me if you see me hey everybody welcome to rapid 2022 here at the 3d printing here at show and telling stage uh this is insane and unprecedented because we have amazing people coming up to show you really cool stuff and tell you about it show and telling right by name whatever um i'm going to do my best to monitor the chat but once guests come up here i'm not going to be able to do that i'll do my best in between guests to kind of check the comments see if there's any good questions uh you can see rapid is going behind me it's a really exciting time uh let's not um what do you think let's not beat around the bush all right i baby all right my first guest i would like to bring to the stage is sj come on up come on up what's up joel what's up sj sj's incredible on twitter you were known as prince charming yes i love it you brought what for us today um so i brought a bunch of really really really cool parts uh do you want to go small and then start big or do you want to start big and then go small you know what i'm going to leave it up to you oh okay put my water down here i want to make sure we've got all the room okay first part um let's start with the rocket part rocket yes okay i like rockets so this is a rocket brush chamber printed in a material called gr cop 42 gr cop 42 so it's the top copper copper's copper and then it's like a copper blend so copper is one of the hardest metals to print because of its thermal conductivity which basically means that it absorbs heat really really well but we have copper hot ends for ffff exactly but it's really hard to print because when you zap it with a laser for our laser welding process it absorbs the heat and then it doesn't want to print oh so rather than using the heat to melt it together it sinks it away correct so there's like a lot of tricks and things that you have to do to get copper to print yeah go ahead so obviously you found the tricks because this looks incredible i know it looks even better when it's fully finished oh look at that so this is the copper part after it's gone through a full heat treatment process inspection polishing the whole shebang so this is how it would be delivered to the customer and then this is how it comes out the printer this is a thrust chamber correct i would imagine the specs for that are pretty precise and so when you take apart and do a finishing process on it it's going to change its dimensions it's going to change its dimensions but for uh rocket parts with tight tolerances a lot of the tolerancing is for the flow path of the fuel and the gases so when you do a lot of polishing you want like this special surface roughness so that the fluid flows through it super smoothly it doesn't get tripped up it doesn't get caught on any powder blockages or anything like that okay so i mean when you press something like this you don't it it's it's fine to finish it you're not going to be out of depends on the customer depends on the drawing i'm going to clarify for all of the metal and people it depends on the drawing whatever the drawing tells us is what we make it to metal am is so metal additive manufacturing correct is is insane and obviously it's showcased here at rapid tct uh by many many people but still a lot of people out there they don't know that much about it so i mean thank you for clarifying that i'm glad you brought that up because at velo i'm i'm a little biased but even before then i was biased and at velo i think we do it best and i can show you that with a really really tiny part so in metal am tiny parts are really really difficult to get so we wanted to prove out repeatability and reliability across the plate as small as we can go so are you familiar with microns yeah like small pieces of a millimeter so this is yes these are 600 microns in strut diameter [Music] yeah okay correct and then we just brought them into our software we repeated the lattice all the way up and then we just let it print free floating in the powder like it's not attached to a build plate it's not welded to the plate the powder is just there and then we're just zapping it over and over all the way up repeated so then may i yeah please it's my favorite part how do you get i guess you have the the metal powder and the laser zaps it layer by layer by layer if it's just free floating in the powder and it's not on the build plate itself how do you how do you get such corners like i i guess like the powder doesn't shift the powder doesn't shift we have an elevator that slowly goes down but the real secret to our sauce is our recoder so we have a non-contact recoider as compared to other legacy machines what is a recoder um so in metal powder the piston brings down the plate and then the recoder sweeps powder across oh that that uh that silicone broom thing yes it's normally silicone it's ceramic it's a blade it depends on if you have a magnetic material or a non-magnetic material right you can easily think about that yeah some people use a brush but then there's a whole philosophy of brush versus blade so it's having a non-contact recoder is just we're in a completely different field over here okay i have to ask so is it personal preference or are there actual studies that show certain things work better there are actual studies that show certain things work better so if you have a blade the philosophy is that if you're using a blade it puts pressure on the powder and then it will consistently dose the same amount of powder every layer because the blade is the same whereas if you have a brush it allows for little defects to pop up in the powder so if you're doing something really really delicate or really fine or really small the brush will allow that small thing to keep forming layer by layer it lets you get away with a little bit more let's get away with murder technically but i never i didn't think here on the stream we get to hear getting away with murder we're talking about metal am this is fantastic okay we've got this is probably one of your favorite parts you said absolutely one of my favorite parts this this is awesome but i see your stuff down there we do have other stuff down here um so do you want to go why did you want to go tall now both sound great i'm this you're running this part man all right then we'll go tall i'm really short this tall this yeah this part is uh half my height so you can flip it over one more time sure oh wait flip it over the other way yeah i could do that because that's the way it was printed there we go tragedy as a metal part impacts the love host in the head this is massive i know and this is a 3d printed metal part correct okay which metal is this this is inconel which is a super nickel alloy a nickel owl a super nickel it's a super nickel so what does what makes this nickel alloy so super it can survive really high temperatures and stresses so we put them in a lot of like large gas turbines we put them in rocket engines they're pretty lightweight the reason that they're so great for 3d printing though is because they're very difficult to machine and weld and they're kind of like a pain in the butt conventionally so when we can 3d print the shape it's like oh my gosh this is like life-changing people get so excited the final form is desired but it's a pain in the butt to correct if you do it anyway other than 3d printing it's time-consuming it's painful so you probably print with a lot of this a lot of it a lot of it and so like we can also get parts like down cost competitively with this super nickel alloy as well so you get better part performance better material properties um and faster lead times yeah go ahead it's a rocket nozzle okay it almost looks like a chess piece it's a giant chess piece yeah so you've got your internal things here people normally have flow passages here you'll see a lot of uh you want to pay attention to like these little things here because they'll run fuel through here and like soak them all through here so i see yeah this part of my additive is so crazy for rocket motors is because there's all those intricate pathways and you can take advantage of building for additive to make sure that those are consistent the same and we can also it's hard to get that conventionally as well i would imagine it's really hard it's really time consuming in a lot of parts yeah it's a lot of parts this is cool i know i like this a lot when it does say it does say fellow 3d on the side it does it's a demo part it's a demo part so um you can see the side channels but when you have like other engines or pieces like this you'll see a lot more intricacy uh when they put them in actual use so i have to ask in a supe super nickel alloy as and metal additive part the size if someone wanted if someone if i was a customer and i said this yes what would you put me with ballpark we're not holding you to it it depends on how big your part is and it really depends on how tall your part is yeah i see how big it is but it's also like how wide how complex okay um a lot more really complex yeah i'm gonna be honest with you i'm gonna ask you like so you came to me and you said i want to print this part i'm going to ask you so do you want thermal heat treatment do you need polishing how much inspection does it require do you want the light scanning inspection do you want like a cmm inspection um is it going in a rocket engine do i need qualified powder like there's a lot of questions to go into a quote assume i answered those all correctly then i would ballpark you sub 50k okay but conventionally i would be able to even approach that no um i could print you this part in less than a month and get it to you if you really needed it but if you wanted it done conventionally i've worked in aerospace to get a part with this many pieces all stuck together we were working on like 18 months to two-year lead times um so it's it's really incredible the fact that we can go so quickly with parts like this that is fantastic all right oh there's all right now we have like now we're going wide apart down there i'm gonna need joel to lift this one because oh the comments are saying that's awesome uh blown away by that they should be people should be blown away because this is i showcase a lot of consumer level things on the show and show the the toys that are used in the industrial side yes yeah grab it you want this part to face the back of us wait which part um this part go to the front put that part on the front yeah there we go yeah yeah gently gently gently oh you're worried i'm gonna break this i'm worried you're gonna hurt yourself um so what is it uh so this is called a stator ring okay it's i am not a gas turbines person i am not a pump or flow person i'm an additive person so it fits between an impeller and a turbine and a pump and so the function of this part is there's normally a series of parts together inside of an engine and they work together to control flow of fluid as it moves through yeah okay and so that's essentially what this part is for so um in a previous life we had to print one of these for an emergency outage so um when i previously worked if a part goes down or like there's an issue normally like to order a part we would keep large inventories of parts like we would have like a warehouse stacked full of parts that look just like this in case there's like parts if we had to because it takes to make right correct um it takes about 18 months to two years to make a lot of these parts that's like a normal lead time for a casting or forging or something of that nature and so what we would do is like they would call us and be like hey can you 3d print this and we're like i mean yeah we can 3d print it yeah so when you can eventually make it you have to like weld all of these little veins in all the time yeah go ahead show them i promise i won't hurt myself flip it around this way because there's like little supports on the back uh yeah so normally these are welded in manually one by one so you i remember speaking before the inner ring and the outer ring were separately produced yeah and all of this internal geometry was created and welded into place correct it takes a while i've seen it done it's exciting it's one piece it's added if it's one piece so when you order it you don't have to order like 40 pieces you just order the one piece and it's amazing right here let's and you can spin it around sure so it's really exciting in metal additive right now because we're finally broaching into bigger and more lasers and so this is one of the biggest parts that we've printed diameter wise okay and then the other part that i showed you is one of the biggest parts we printed height wise i see and this is still smaller than the machine's build volume this is slightly smaller you can go maybe an inch on each side okay that's still massive yeah uh considering that like my normal build plate for a regular machine fits inside of this circle oh hey sj ring yes uh i'd like to order a part it looks just like this what would you quote me for it um i can't actually give you a number on that no um we just started with like all these new laser initiatives so i can't actually give you a number on this okay but it's probably a lot it's a lot but it's less because we have more lasers now oh yeah oh so the machine itself it's not here i'm going to set this down lay it down before we knock it over yeah oh this is a sapphire xc from zello 3d snap fire i know xc xd extra capacity extra extra capacity what makes the sapphire so cool um there's a lot of things that make it really cool but i think that what makes it the coolest for me is that we've really worked hard to properly build out the software that also supports the machine so i would imagine software's super important it's so important i remember uh oh gosh a couple years ago when i was at form next with siemens they talked about the laser path yep like that that's huge right it's huge but also um translating the file over so um in normal 3d printing you work with stls uh for us we work with the native cad so you would send us your solidworks file your fusion file your step file your parasolid and we would just load it right into our software well it makes a lot of sense yeah on the professional side you would want to have exactly what is needed correct and any sort of conversion to an stl you might lose resolution in geometry or whatever correct also stls get really really really big really big um really big and then you have to repair them sometimes and that can be really challenging yeah so when we get to use the native cad file it's also really easy on designers as well because they don't have to worry about well what resolution do i need to have this at they can just send me the solidworks file i plug it in and then it prints directly from their solidworks file that's saved in their uh their company so i know like i it's one of those things where people don't realize how time saving that is but if you have someone well it would be great so in on you know in 3d modeling there's people that use solidworks and blender and these and they have to then um reduce the mesh correct stl and then we can print the little key or the pokemon or something like that yeah um but but being able to consume the actual file that they work on would be amazing i know it's i love it uh i believe our time is it's coming to a club when you have so much cool stuff it goes by so fast yeah sj tell everyone at home if they want to learn more about you or what you do at fellow 3d where they can go um if you want to follow me on twitter it's inconel like the super alloy but e-l-l-e at the end you are pretty super thank you awesome thanks for having me joel i really appreciate you coming dude bam oh thank you are you going to help me get this i'm just waiting for the tragedy what do you mean thank you here we go so we've got more to go sorry so here while we get our next guest ready i'm going to take a look and see if i can't answer some questions in the chat said i love seeing the industry the industry machines as it trickles down to the diy over time exactly plus being able to show you the professional and the industrial side it means that we can inspire those who want to get into additive all of that experience that people have with consumer machines in their garage their school their maker space it directly translates into working with all of these crazy machines behind me and i think showing what they can produce is super inspirational dusty knuckles 3d printing nerd mike needs a little boost lots of background noise that did go away sweet trying to catch up sorry hey joel how was the print shop going hope you were all squared away uh the print farm's actually going really great i have 18 machines stood up now and i'll be getting to between 25 and 30 once i'm not in detroit and i'm back home and i can um take a little time to get that set up i've done a lot of etsy orders for a lot of the popular models like the cinderwing dragons and the um uh the hex 3d models and right now what i'm trying to do is attract more manufacturing clients like i just finished a 1200 part order for someone and uh i just bid another 2400 part order and so i think part of the print farm is great because i i can satisfy the needs of people who want these really articulated models or the sort of thing but also i have the capacity and the size and the ability to do manufacturing jobs and to satisfy the need for the people that need inexpensive but high quality parts so that's kind of fun for your next guest pretty impressive printer prawn that's true what's that is it next guest time yeah awesome here we go okay i gotta close this my next guest is luke what up man hello hey man good to see you good job do that there we go this is luke from polymaker hello everyone you look fantastic thank you super dig your suit thank you very much i'm keeping it blue i don't see a bunch i appreciate that yeah i don't see a bunch of metal parts here so well uh we're polymers right yeah we are so what do you got for me i have got some carbon fiber molds okay so oh this is a carbon fiber sheet right here so this is a carbon fiber piece you can take that off have a look oh look at that shiny shiny i like that and then oh so this mold so essentially the carbon fiber was put into here in that mold and pressed together exactly yeah so it's using 3d printing as a tool so we're 3d printing negative molds this one is an open mould um this is a pa6 oh so uh carbon fiber nylon carbon fiber nylon yeah this stuff is tougher than woodpecker lip i've never heard that term before but it makes total sense so you can you can sand it down get a really nice smooth surface right prepares it for the molding then typically use like a pva or a release agent uh did you say cfor gf this one is gf okay so glass fiber this is glass fiber okay sorry about that so we get extra stiffness from the glass fibers well and the sandability is incredible yeah it doesn't chew up right so you can just work it you can work it with electric sanders yeah really like get some weight into there right anytime you do that with a low temperature polymer you start pushing material rather than sanding it rolls and it rolls up yeah this stuff though like here's the thing a lot of people out there they they know how sanding goes there's plenty of people who cosplay or build things and uh they have that i sand i die i sand again sort of sort of mantra um but being able to to stand this it is so smooth and i and being able to put weight behind it like i would imagine a glass-filled pa6 is a is a wonderful material for this it's great i mean and you can print this on uh on open desktop printers right this was printed on a lulzbot i think it has six okay so i mean it's not limited to like the high temp machine you don't need to heat the chamber you don't need an enclosure well glass fiber helps with that right yeah so it actually reduces the coefficient of thermal expansion really so uh you get no warping uh where it's done no warping okay it's warp free we have warp free technology or free you heard it here well free technology so um you know very flat and that you see i printed it like this up i think i did four perimeters maybe like a 20 infill well that's it that's it it feels solid it feels heavy right it feels heavy and solid yeah so i wanted to get a good amount of material in there so then you can work the surface and then the once uh you lay the carbon fiber onto it so you wet the surface with resin first then you put a sheet down of carbon fiber and i've been learning this myself right so easy a marketing manager can do it right so you got to like get your your resin down one sheet of carbon fiber and then you build up i think this one has four layers oh it's it feels it's got some stiffness to it it's got some rigidity to it but it's got a little bit of give light yeah this this weighs nothing it's grams nothing and then um and then you put the whole thing in a vacuum bag so you can do it like the industrial way with the proper vacuum pump what i did was just use a um you know those storage bags when you put your winter coat away and you want to suck all the air out and they have like a vacuum you did that it worked so well it worked okay so you have like i had no idea but that's amazing to think about i didn't even think about that one layer of like a breather fabric which lets the air move through to the to the to the valve but there was enough pressure in that that that bag right enough enough what do they call it though you evacuated enough air to create the suction to be able to hold it together and that's it so you have one bar which is one atmosphere of pressure forcing down on it right and the beauty about this material is it's got a heat deflection temperature of 191 which i think is like three seven five fahrenheit yeah yeah really hot so you can bake it in the oven under vacuum uh to then cure it so if you're doing a pre-preg carbon fiber this is a carbon fiber sheet it has the resin already impregnated in this is what the aero guys the f1 guys are using i see you can cut it super easy you can lay in all your fancy parts uh this one is just like one sheet but if you need really complicated parts that's what they do okay and then they have to do like a ramped um oven cure so for a material like pet pet g or pla you know you wouldn't be able to cure at the high temperatures you have to get up to it that's why you need the nylon ah okay and you set it like a test six this is so what's the principle what is the print temperature of uh of a gf nylon it's 270 to 300 oh so even a standard hot end can do it yeah a standard all metal hot end that's right no problem no problem at all and actually the bed uh you won the bed at 50. it's cooler than pla right yeah yeah and that's the world free technology so we slowed down the crystallization rate of the nylon okay and if you have the bed too hot actually it speeds it back up again so it's a really accessible material for like for desktop printers what's on your build plate oh if it was a low spot then pei yeah pei i like to throw a bit of magikoo down okay holds on just fine yeah okay so then what did you get down there there's another type of mold this one is um actually a pa6cf oh so this is the carbon fiber this is carbon fiber okay and then we have a 3d printed core uh it's a tight fit so this one has like an offset of um i think 0.5 millimeters and it's designed for um like a 200 gs to pull it straight out like that right 200 gsm carbon fibers you lay your carbon fiber into the mold first and then you take this is a 3d printed core this is just designed for one layer so we get the stiffness from the carbon fiber and then the core is then 3d printed this is a steering wheel for a race car there's like other parts that come on here that have your buttons on oh this has oh for like an f1 steering wheel like that's sort of the buttons and the controls and okay and then this one can just like pop in the mould give it up and then you wrap all your carbon fiber over and then vacuum bag so this is like a different molding technique so we're using 3d printing to create the negative mold and then we have a positive core in the middle and then it's all sealed together with the the epoxy and the carbon fiber on that so it makes a very strong part and right yeah incredibly lightweight and incredibly strong there's nothing doesn't it yeah absolutely you know they're fighting over grams right so then for this this sort of way of making it would um drone like drone frames drone bodies be be made similar that would be a great application yeah so i think um there's uh because they're fighting for grams too right right yeah it's all uh it's all about lightweight strength to weight ratios right yeah yeah and carbon fiber is the best it really is yeah um so if you need um high strength low weight then uh this is uh you can also play with the infill of the core to try to get the the weight down of the core as well oh well and plus being this um being able to do this with the carbon fiber it's it's a cheap way to do prototyping as well yeah so then you can you can test the the proper infills for the core without really using a lot of money in order to get the right one you change your design as many times you want and just print a new one right yeah yeah no tooling involved no one no big investment right that's great and the mould itself is uh it's less than 500 grams of material the cores obviously uh go into each piece but um with the the nylon you can you can make a lot of hits out of one mold oh yeah absolutely okay so then luke here's a question for everybody out there um these are poly maker materials yes and what you described as a process is are carbon fiber sheets and epoxy so i don't know are those easy to acquire yeah you can get them online and often they'll sell kits so they'll sell like uh you know one meter of carbon fiber sheet you get the resin enough resin with it so like a home kit for you know guys like me and you who want to try to make some carbon fiber parts at home it's really really affordable really affordable i think i got like i got a kit for like 50 bucks oh and that was like one meter of of sheets that sounds like quite a bit yeah enough to i mean like once you build it up yeah you practice it's you gotta you gotta learn get it into the corner it's gonna be tricky you gotta use your brush and stipple it in yeah yeah but this is really neat though because you're talking about accessible materials and an accessible process for people that have like you said a task six but if someone upgraded their ender three with an all metal hot end they could do the same thing totally that's cool so it's uh you know it's using 3d printing as a tool you know it's a means to an end and we want to create the materials that enable that that makes sense all right i see other materials down there what do we got going on hey david yeah chuck so we're going to this is back uh onto our pla range okay this is a really nice model that uh we uh we got sent in and this is uh using like uh we have now a range of uh i think five or six different plas oh not just different pla colors but types of plf types of pla so um you know the polymax pla yep so the parts that are under tension here from the strings uh a polymax pla again the headstock there's a carbon a real carbon fiber tube i think you have to any sort of instrument needs that there is so much tension from the strings right and then the the chin uh chin strap or chin piece i think i'm not a violin player can you tell like this you look like a professional uh this one's polyterra right so this is our new army red color it's a good color and then the body itself is is polylife pla so you get a nice range here have a feel it feels great i mean plus that carbon fiber rod there is going to weigh nothing and then being able to just hold it up and to be able to do stuff it i have to ask so what did this what does it cost because when you talk to um people in like music teachers they're always looking for a way to make quality instruments more accessible to their students and you know i none of my kids were into playing classical instruments but i did have friends who did or friends whose kids do and it's not a cheap thing well i mean yeah so these individual parts right so the non-printed parts you need the the keys the carbon fiber rod i think you can pick up for like uh 20 bucks right and then the weight of this it's less than one spool right it's less than one spool okay so so with this model and some pieces you've got look at an instrument you've got the instrument for less than 50 bucks easy wow did you ever have a ball yeah you need you need the horse hat uh we got one on our booth that was a guy come by he tuned it up for us that was david hey wait i'll see where's my microphone okay ready here we go it sounds good well with this sort of instrument obviously you're relying on the the negative space within the body to help amplify the sound that's right and it's doing a really good job like i'm impressed that's not quite at all and there's a lot of uh background noise in here i think um if we i think uh i think he's working now on an amplified version get some pickups inside the body i mean look with 3d printing complexity is free right yeah yeah absolutely thought about it so he can just uh tinker with his designs make a an electric version and that's it right that's uh you know we're making uh making it accessible of course we don't have the stand in the poly maker teal how you doing man good but i think this is the last part isn't it that's it that's it so uh how are you doing like this is a wonderful show great to be back you know finally last uh last show i covered the polymaker booth we uh we played that uh the tippy tree game yes that's right which was a lot of fun we've got a different game now though right we have penguin peril penguin in peril it's not i mean if you uh i don't want to say break the ice but it's inspired it's inspired by breakfast it's a popular game uh i designed it myself uh and i i i you know you can knock out the blocks it's really fun like well it's for kids but like actually i enjoy playing it well luke did something interesting because he said i saw something and i thought i could print that right right i thought that's how we all start with this right i can design hexagons i can extrude yeah yeah this is my level that's because that's it so then are you going to release it it's already out there yeah is it where can people find it probably make a thing of this download it files it for free it's coming back man it's coming back i'll throw it on thangs joseph prush is going to kill you [Laughter] feel free to remember to put it wherever you want yeah you can change the penguin for i was thinking i should do a beehive right oh a they'll be on there and do beehive you know they make hexagons and bees it makes sense right well here's the thing so you out there right now if you're watching this and you can go find luke's penguin peril game on thingiverse or thangs or yeah there's a somewhere poly maker on polymer there's a video on the point maker youtube channel and there's a link to download the files well i'd love to see it printed and so if you print it please tag me on the socials and polymaker too it's really fun surprisingly fun all right joel this was fun man great to see you again we'll have to stop by the booth the show is still going and i think um you're getting some rosin for a bow right yeah the rosin's coming in tomorrow okay so we're finally gonna have some live performance okay we'll stop by the booth and we'll actually get this being played by someone who's not you we've got four of these so we're like you know almost an orchestra almost the violin section anyway thank you lou thank you i appreciate it man hey have a good rest of rap but i'll see you around good to see you want more oh there it is hey everybody that was luke with polly maker and uh i love luke i love that guy such a fun guy to just chat about materials with the polymaker booth is always something that feels very inspiring just because they have so many colors out there you just a lot of times what happens is i mean i've printed lots of things but being able to browse a large selection of colors and just you you sort of you're drawn to a color and then you love the color and then you think i can't wait to print this in that color and that's what it's like going to the polymaker booth that's always a lot of fun sir will a 3d printed banjo would be cool that's a good idea will let's see brandon joel will you be doing a meet and greet um no not so much uh i don't think so i mean if you can find me on the floor i could do that proper printing made a guitar from marquis c yes proper jean over at proper printing is a stellar human and i i love that guy so uh he did make a guitar he he didn't just make a guitar he made a bunch of stuff and it was crazy mitsuo level makes me want to print a bass saxophone that would be interesting because you have all the i don't know what they're called the valves or whatever that you have to that you have to press to make the sound nltmw the title song from ghosts and goblins i love it where is that waiting for the chat manny's engineering you should do a 3d printed guitar it's true uh zombie hedgehog came from the polymaker discord thanks for the coverage thanks for watching that's the goal we're just trying to find cool stuff to show off you know valor hm i just love your broadcast joel my broadcast loves you valerie colton miller will be going to the block party there is a chance of it we do have some things on the schedule that have to get taken care of here at the show and it's not really stuff i can talk about but it's just i have blocks of time that are that are covered so if we can make it happen if we can make it happen we will are we good david are we good we will be in a second we will okay hey drawer our next guest is almost here there it is mike kelly penguin peril penguin peril that's right battery jam with printed whistles yeah with the wall whistles there's that default whistle model that comes on all the prusa 3d printers and i remember when i did that episode that stream with neil patrick harris and he printed the whistle and then he started blowing the whistle and it was really loud that was a lot of fun tiny cassettes 3d printing nurse so was jason ldl was he there jason is here and actually tomorrow are you going to ask me questions or we're just going to have a conversation yeah okay you want to do it come on up thank you my next guest is drawer from nextjet hey dan how you doing it's been a while it's been years last time i believe we showed your stuff was 2019. yes it was and which city was it it was it was here in detroit was it it was here in detroit in 2019 that's right here in detroit gave me that tour and we should we got to see the uh the really tiny that's right so what do you have today to show us well the biggest leap i would say is in metals okay okay already in 2019 we started to ship some ceramic systems that's right you know and i showed you some parts that i didn't see this though yeah this is a part of a watch it just took a small it feels good though ceramics feel wonderful and it feels even better if you do it on the extra machine now ceramic has so many advantages this this industry didn't yet acknowledge i mean from you know heat resistance to many many uh wear resistance uh characters yeah and the reason it wasn't appreciated in the past is that ceramic everybody know that ceramic has these great attributes but they don't use ceramics because ceramics is impossible to machine but right everything has to be yeah because it's it's not an easy process to get a detailed ceramic part yeah it's very very very strong in compression makes sense very strong but it's if you try to there's no elongation in surroundings okay but when you need ceramic parts with a lot of details and because you cannot machine it it's very brittle you have to give up and go into other materials so people didn't really value their potential but since we met we started to install machines and we learned a great deal of new applications okay and things that were impossible all of a sudden became possible oh really that's that's always a wonderful discovery to make it something impossible is now possible is that part of what's in your hand right there well this is actually a metapod and that's the second major beautiful thing that we took advantage of covied and we managed to finally bring the metal machine into the film so we have our first installation here in new to detroit really yeah that's awesome congratulations and actually i'm holding one but there are many many other parts made here in michigan since the installation which was when may 2nd i think oh it's two weeks ago it was a couple weeks ago troy yeah like it's already 24 7 and there are dozens of parts oh i bet they're happy beautiful parts i didn't bring them with me but uh like a walking distance from where we are right now if you're watching this from the show go to the xjet booth and look at all the parts we're right at the entrance it's you can't miss it ask for the flowers that we had an open house we wanted to show the world what you can achieve in two weeks from installation and actually that was remarkable and then they surprised me they gave me a bouquet of 12 beautiful roses printed on the machine a full rose printed in metal in metal do you have and you have them here i have them here and they were they are in the booth we'll go take a look at that after that yeah well let me see this metal part that you got yeah and and you can see once again it's all about the details when you can get to the resolution that we do when you start to use metal technology without powder it's the only powderless technology that exists really yes or in metals oh okay okay in metals because most of the technology apply a great idea they have a powder bed okay and they do either fusion by lasers or by electron beams or they bind the particles together by binder so the jet binder yeah yeah what we do is completely different we start from scratch we start we'll give you some room to work here okay so we got the tray actually two trees very long trays 20 inches long trays of whatever you empty trays oh empty strip empty trays yeah it's like a a metal something that comes with the machine sure so imagine you have an empty tray and now you want to print this all you need is to create a file this is it system will take care of inverse the shrinkage that is happening in the in in the furnace oh okay so it will take care of putting support wherever you have an undercut channel everything that might fall if you don't support it well i'm looking at this i would imagine there was a lot of support internally not so much actually most i mean not a lot of quantity what allows the movement actually it's a tiny sometimes even as tiniest 10 microns layer of support that keeps it like that how do you do that okay the beauty it's a combination of two things the most important thing is that we use soluble support that's the real uh adventure that was the really good use of the last few years soluble means that instead of using manual work you can use the power of water yeah just water just water yeah but i've i've not heard of soluble support with metals before no nor with ceramics so we have them both now it's not the same material okay the the support structure is different but in both cases it's completely soluble and this allows to make a piece of this nature a piece of cake but you said 10 micron like that's nothing that's not fair that's nothing well the the ceramic particles are way way below one micron and also the metal particles are below one micro so when you you touch it actually you can't touch it so it doesn't feel like powder it's sub powder side or sub micron size oh and it's in a solid state and since it's so small we disperse it in what we call ink actually it's a carrier okay now unlike what my mother believes i hope she doesn't listen now but um and many people actually a lot of engineers come to abroof and think that it is a molten metal no it isn't it's solid state but it's so tiny that it's like swims it's like a dispersion it swims in the lake it swims yeah it's so small so tiny and in volume it's negligible in white it's 50 but in volume it's not even you know so then it's it's almost like it becomes it because it's it's so small it's it it's a fluid in a way well it is a food you don't see the particles yeah the the naked eye cannot see our particles they are way below the separation of a human naked eye so you don't see if if i give you a bottle this bottle will it doesn't look like an orange juice it looks like a industrial orange juice so it looks very smooth and and then it via a complex system that includes pipes and pumps of course and eventually top of the line inkjet heads a piezo inkjet head i would imagine they would have to be not what's in the printer at home sort of thing no no this is the complete i'm sorry sorry my friends it's not for home use don't try it at home but basically it's extremely extremely small particles now that allows us to jet it without hurting the heads or the heads can live for very very long time we jet it only where we need it we have like 12 000 nozzles each one at least 10 000 drops per second per nozzle so if you do the calculation it's more than 120 drops per second 120 million sorry what did what was the time to make this part now the beauty of the raster system we have a raster system that goes over the tray what a rust raster i mean we print a lot oh i see what you're saying yeah a lot at the same time so if you only make one part or if you have two or three this size maybe even 20 pieces on one tray it will take the same time so we are targeting that's great yes so we're targeting production rather than just so if you make one it can take you a couple of hours but at the same time you can do 20. so if you're looking into production and you are welcome to visit and see the parts on our on a booth and and parts made by our new customer here in michigan why well we have to stop by to see the flowers you need to see the flow i can't believe i didn't believe in the flows that was nice yeah oh maybe that's an interesting one can can ever yeah yeah this looks dc this was already on the news last week this is an this is a project i can't tell all the details this is a lot of knowledge of a european user we can keep it anonymous yeah no i think it's already public but the the guy the guy is working for a few years now to create a new level of engine i'm gonna say it looks like a piston it is a piston it is a piston and he wanted a to create a piston made of ceramics to go into the european ultra car the car that you do zero to 60 miles per hour in like 2.2 seconds right in no time in no time like 3 000 horsepower i mean something crazy okay put ceramics in an engine well we will this is just starting it's a mechanical properties test and we hope to succeed it's a long term process however in in a piston in a cylinder there's a lot of compression oh that's right which the ceramic can handle ceramic can handle now there is also stress analysis that is very common today so you can analyze where is the stress and then you can reduce and create geometries only in additive manufacturing you can create geometries that will optimize and put the material where it's needed rather than just the food so that's risky being able to use ceramic and analysis to be able to put it where it's needed and to be able to that's cool and it's even cooler and let's talk about temperature it's even cooler why it's cooler because well actually i should say warmer in ceramics as i said earlier it's more resistance to heat actually it can reach higher temperatures which means for the mechanical engineers out out there it means that you can get a more efficient cycle a thermodynamic cycle is more efficient because you can get to higher temperatures right so you can use the same amount of energy same amount of fuel and get a better outcome of your system so you get less weight because the material you can see is less weight also you can cut weight because you analyze the stress and you can put the material only when you need it but it's great though because ceramics they can withstand heat and a lot of compression and that essentially describes an engine exactly now it's only the beginning so i don't want to check everybody's expectations and i don't know all the details you don't have the supercar right here all pre-made actually the ultra car is beautiful and you can google it and it's already published i mean and all the uh the name of mr spirus and the it's great i mean this is an incredible greek team out of athens that uh does it okay and but they have huge progress they have a lot of followers so it's already published uh not just details of course and sure how many how long out are we are we months or years i would say probably more than months but i guess very few years okay so we'll see it in the 20s we're not it's not like okay it's not 10 years it's not five years but it was this would be a massive thing it's it's it's it's a it can be a world-changing solution and again it's still a long way ahead of us there's a lot of things that need to be tested and approved and confirmed but the geometry is confirmed already and that and that's the contribution of our industry and specifically exit that this is the contribution of additive manufacturing and this is what additive manufacturing brings into manufacturing not mass production like i heard before making millions you know what making millions there are better technologies than any manufacturing but if you need to make hundreds of thousands if you need production but production for specific applications production that changes the nature the the economics of things editing manufacturing comes there and we see more and more of our users both of ceramic and soon also on the metal that are using the technology for production even of consumer goods now so really yes okay okay thank you david um one of the things i wanted to ask and this and you actually kind of tie into it really well so you've been in the industrial side of am for quite some time and too long you mean i'm not gonna say that no no no no it seems like we're getting to a point where it i don't i don't know if uh um maturing is the right word but we're getting to a point where the industrial side is really sorting to to to really showcase what what the additive side is made of like it's not just like you said the mass production but these bespoke um uh polygons like these these these designs that are made in no other way and being able to make it and materials not thought possible and where where do you see x-jet going in the next couple years when we think about it like that like do you like ceramics are big you're now into the metal stuff is there what's on the road map for example well there's there are plenty of things first i would say that with the ability to use extremely small particles we gain sintering temperature which is much lower than melting temperature so what we hear from people here at the show that so it takes less energy to center this and it is a lower temperature this is even not it's not only a savings of time and energy it's more than that by the reduction of the temperature approximately 100 degrees almost 200 degrees celsius almost 400 degrees fahrenheit lower than melting point that's significant that's significant compared to the traditional aim that allows people to get less distortion right okay less roppage that means that you can get much better near net shape much better accuracy and much smaller features that will be kept in the sintering furnace so this is when you go and start to see that i'm talking about parts that were made in the last two weeks here in michigan by our user and what i learned from him just two days ago is that he manages to sinter in a much lower temperature i think it's 180 to 200 wrist sensors below what he used to do before with great yeah and and that allows him to keep geometry alive even very challenging inner channels very very challenging small features that were impossible before and that opens door to new application and now obviously the obvious industries are you know automotive healthcare medical devices dental aerospace satellite a lot of thing i mean but but the beauty is that it opens door to new design and and these stakes and that's why we're here this takes understanding and acceptance of the designers and design for additive manufacturing is key and i know many people say this slogan over and over again finally when i go i give some free lectures in university you know to develop the industry what i hear today that i did not hear 22 years ago when i joined the industry is i hear young students in second year of engineering mechanical engineers they already talk about design for it even affect you not many but i start to hear questions from young students so i think for me it's like a fulfillment of a dream because if people will design for additive manufacturing they will enjoy it it's not about just reduction of the cost like some people think no it's a lot more than that there is enjoyment there absolutely yeah it's enabling it's making the impossible drawer it's always a pleasure man i really want to thank you for bringing these by emperor for telling the audience about all this cool stuff if you're here at the show go to the x-jet booth there's some flowers that you've got this will be in our selfie area so you're welcome to make seven that's the second printed piston the first one was sent to greece so for testing so you can keep that oh i get to keep this yes hey it's been a pleasure it's been a pleasure draw thank you very much well that was exciting it's always it's always wonderful hearing about the ceramic side from drawer uh i don't obviously i i i showed it off in can i crush your party oh my gosh it's joe prusha dude what are you doing i'm assaulted again here my microphone's right you have to talk into here i almost thought i can crash a party for it my goodness look at this well we got some comment we got so happy to see you man dude it's so good it's so so good as you've heard joe the prussia family has expanded because joe and team have acquired dave and printed solid yes it's one it's wonderful and uh you've also have trilab which is an industrial delta machine yes i i hope i hope we can you can see paul versus family tomorrow tomorrow yeah the goal is we're going to do some booth visits tomorrow and at least one two three booth visits are gonna you're you're growing you're taking over more booths yes all right thank you enjoy the show man thanks joe hi everyone it's live you never know what's gonna happen that's um that was great so yeah we'll be doing booth visits tomorrow like i said uh joseph and the family it'll be um it'll be fun ah he threatened me he said last night that he was gonna be behind me without pants on and i was a little worried but obviously everything took care of itself kenneth's saying joel and nero should go live to and joe should go live together we might have to do that sometime i am scheduled to go on nero's live stream yeah is it time okay well come on up this is jason right jason right you got it hey jason i'm joel nice to see you nice to see you i gotta just splatted out some parts so this is just with carbon hi everybody now carbon if i remember right was that um the ted talk that went kind of viral a few years ago right you got it uh probably about almost five years ago with this it's quite a while for you exactly a while i was their first ever user i used to be a customer of them before i joined the team i worked in special effects using technology oh really well i um the first time i saw carbon part i was visiting tested and uh adam savage was showing me apart from a carbon machine and he was blown away as was i that's great yeah me and my co-worker tyler murray actually worked on that for adam just really showing the world what you can do with this different technology because it really is the material can i i just want to touch the parts please go for it look at this this is so cool isn't that really neat oh man so what you're looking at there is basically an elastomeric print it's our epu-41 black material i've heard of tpu yep what is ep so it's an elastomeric polyurethane elastomeric so not a thermoplastic elastic or urethane it is an elasto wait so we're basically apu epu we're a two-step process and what we do in our process that's different from a lot of other technologies is our materials are dual cure materials dual cure durable cure so what you might be used to and let's say an sla or a dlp like a form labs machine it's pretty similar process but we have a secondary step so after we print in step one we print we shape it with light okay and we're in our green state about 80 percent cure at that point that's that's a typical scenario right absolutely okay okay but then we go into a convection oven depending on what material from four hours to 12 maybe 15 hours and that's where the polymers crosslink can bring out these mechanical properties ah so the green part really sees its end use capabilities after after a heat treatment you got it now if you think about this that's on a basic level of just printing apart yeah yeah that two-step process enables us to do some pretty cool stuff we can do coherent bonds in the oven between two different materials which means okay coherent what is that what do you mean by that so now i don't need to hope it's not a dumb question no not at all okay now we can instead of using an adhesive later downstream we can take a rigid part and an elastomeric part combine them together in their green state go into the oven and have it cure through and cross link through the material panel oh so it is it is a it is it is it is an atomic bond at that point you pretty much got it so it really opens up the world now we can do inserts differently basically anything that can take 120 c we can program in now into the build into the chamber going into the oven and have it cured just a different way of looking at it i didn't even think about that but well a lot of times when people think of okay i'm gonna use like resin printing whether it's consumer or form labs or whatever just prototypical resin 3d printing it's known for its detail absolutely some machines are known for speed absolutely and usually you can print one to many pieces that you then sand and finish and glue together thinking of miniatures or highly detailed models having a two-stage curing process and being able to cross-link different materials like we're talking like rigids with non-rigid like with this rubber with this epu stuff like you're building finished parts that are multi-material one million percent multi-material finished parts and even single material uh finished and used production parts think about a bike grip an inner sleeve is rigid outer might be an elastomer with a lattice and we have that baked in so there's no downstream assembly process think of composites what we could do opening the world of composites sandwiching in with our soft touch materials to a composite structure i think it really opens up lots of applications that are possible that's really cool yeah okay so then so what you're looking at here is what makes this really cool i love geeking out with you jason this is fantastic man i just want to come and do builds with you in the middle of the night so this is a lumbar support for an osprey backpack that's actually in production oh not only do we offer printers hardware and materials we offer design software as well that allows you to take in a design space perform characteristics with open cell different types of lattice types for performance that you might be looking for and populate that design space right there at our printer level really right at the printer level you can export that out and go to another technology you want or you can go right to our platform and print in one of our materials that these are tuned for these can be variable density lattices okay you can really do the world with them we can take data from foam program it into the design of the cells and the structures and come up with what we have and if you see here dude that so this is amazing like it's mind-blowing i really want to encourage you to come up with your with your group and really show your users what's going on up at carbon because talking about it does not do it justice no no in the lab oh this is like i would imagine it's life-changing walking into carbon and people just seeing what's going on there how could you leave special effects and i said so i can learn my 2.0 of these materials and what can be done to go back into entertainment in some fashion with this this sort of stuff revolutionizes the entertainment industry because anytime you have to do a a practical effect it's lighter is better easier to build is better like building parts that are already assembled is better anytime you can make production easier to do faster to do and cheaper to do you've won you design iterations cranking them out you could have four to five iterations right on a build plate right and that's just in a soft touch world now you look at in a rigid world this is pretty crazy so this is a fan shroud okay but what's different about this is this was just material was just released a couple weeks ago it's epx 86 fr epx 86 fr fr being flame retardant you got it okay epx being epoxy you're 3d printing with epoxy so we have urethanes we have epoxies and we have silicone urethanes as well so this is the first ul v zero fr blue card that's come out so this material is in a class of its own so this is going to enable a lot of applications in the automotive space consumer space industrial space but i think it's going to be our first tiny step into getting aerospace to look at us a little differently why is that we're really getting uh materials that are certified to play within that space with all the requirements the fr is important obviously it's a challenge yes yeah so this is is a lower level of it that you know solves automotive industry which will allow other industries to look at us a little bit more serious in my opinion oh you're so you have a bunch of these industries out there and once the first one's like yes then the others will get in line so to speak i mean joel you've been around for a while like showing your viewers all of this the big talk has always been manufacturing production manufacturing production unfortunately what's come along with 3d printing as well a little bit of sensationalism oh sure so now you have a lot of people that are holding back the true adoption of taking it from a prototyping world into a true production manufacturing world and i really think that we can show up at carbon that this is possible you can trust the technology the materials we have validated processes we can follow what the industries needs to do it that makes sense well i mean like you talked about sensationalism people get really excited obviously there's the promise of industry 4.0 or additive will solve the world or whatever you know obviously there's that that that curve and once once we recover from that then the real work gets done exactly and i mean i i've seen you've seen a change in the industry last couple years just where where people are sort of honing in on the skill 3d printing and or additive at scale has been really utilized as a tool itself and not something to just make 500 000 parts of something it's very specific so it's good to see carbon going this way man it's really good and it's really nice like you know what you're doing with your viewers is you're you're showing people and giving them action come back this way you're giving them out to things that they don't generally have access to you hear about but you can't go really that much lower under the hood to get an understanding and to inspire people to say oh my god that might be a path i want to take to figure out to do oh yeah that's what's so neat and that's why i appreciate you so much is you you really open up because one of the biggest struggles with adoption is workforce for this and you're seeing people trying to play catch up now and build up the workforce and we're all like missing in different areas and we needed it to all come together well part of what makes it difficult and just as someone who was who used additive and is now works in additive when you come to a show like this there's a lot of talking points at booths and granted there's a lot of really cool stuff but it's there's a lot of suits and ties it's very professional and so part of what we do especially with the show and telling was very specific and we wanted to get cool people showing cool stuff because all of these booths here have the ability to make cool things just like carbon correct just like carbon and and these people would everyone watching would not have seen this really cool stuff or got to hear you say really neat things and without us being able to do this it's fascinating and i just love every day being up there seeing what we're up to what's not even been announced yet i mean we announced some hardware we're showing off hardware that was recently announced our m3 line which is pretty phenomenal uh just getting closer to turnkey complex geometry production well that's the that's the holy grail right there isn't that the next holy grail i mean if you look at this this this is insane when you think about it compared to three years ago this is out of the printer green cured finished part assembled into the backpack there it goes right there right right here on the lumbar right there or the lumbar support feel how light this thing wait this weighs nothing jason but look well i mean there's nothing there's nothing considerable in it correct but their requirement you know lighter support more comfort breathability and we can do that and we can tune it and tailor it just like we started with the adidas sneakers the football helmets now this specialized bike seats you did say something's not yet announced so is there an nda somewhere i can sign to me and you could always talk behind the scenes and go under mutual at nda but we have some super exciting hardware like our m3 line what's different about our materials for your viewers like i said these are dual cure materials which means there's a part a and a part b that mix together which means that there's a pot light within a pot life we have about eight hour 10 hour pot life oh i didn't even think about that stop watch is on yeah yeah yeah yeah you got to be good up front support your files optimize them in the proper way to take advantage of what you just dispensed economically oh my gosh so there can be challenges as urethanes cure over time in pot life viscosity changes right print plans wait oh you're applying the heat so you have to worry about an exothermic reaction because you're applying this well we do have to worry about an exothermic reaction so we have to slow down at times but our new hardware can sense that force feedback and react to it that's so cool and dynamically changed throughout the build wow the audience is freaking out just as much about this they love it i mean i'm happy to answer any questions of what i can big fan of you and all your viewers shows it's really cool i have to thank you so part of like why we do this is because every one of you at home is really excited about this stuff and interested about it and the way that we get more young people interested in the industry as a whole is to show off really cool stuff and part of that onus is on you jason to be such a passionate person about this i've been doing this for 19 years really so what's your background okay so special effects special effects i work for stan winston and then i don't like the oh really yes so i was at legacy for 14 years utilizing all photopolymer technologies sure i met joe desimone and phil desimone founders of carbon when they were in stealth mode under a different company name approached me at one of these shows five days later i had two alpha machines seeing what i could do with them they didn't waste any time didn't i and i fell in love i fell in love with what you could do with these materials one of the holy grails of 3d printing a living hinge in this technology i can do a production living hinge really nice one too a really nice different materials it enabled all the things that were lacking when i was trying to do this and it's amazing now i'm very agnostic as well the right tool for the right job and i think that's an important thing for the viewers as well right oh yeah what's that we have a question coming in uh met vince mcvince asks can you uh silicon devoted to other stuff like can silicone be what can epx be bonded to other things so there are bonding methods there are absolutely bonding methods to do yeah very good question very advanced question i love doing things like that all of this is through r d and some trial and error but yes you can bond different types of materials oh boy here we go yes and get this ready let's ask as many questions as you want look at this i'm old af so am i and going back to college to get my degree in additive people like this are why see this is working jason this is totally totally important this is what it's about and i just had a conversation before coming down here i know these pioneers i know the inventors that have been doing it since 89 and they are just as passionate as joel and they're just as passionate as me and that's what's special about this industry you're not just doing something to satisfy your need you're entering a whole new social platform world with these people because everyone thinks in a very similar fashion here which is really amazing oh i love it man let's see um uh the guests need to step three steps up to be near the height as me jason's not that bad let's say there we go there we go is that good yeah is that good because there's a robotics you could and they would be comfy and stylish absolutely yeah i mean it's crazy to the viewers i have a i have a sailboat and i print replacement parts that sit out in the sun for two years with no degradation oh really so uv isn't a problem for these materials no i mean they're on our sneakers i guess that's true look at there's andrew sink you know that guy andrew is so glad to see this happening what a great call one of the most talented people out there in the industry but besides that he's like you if he's all over social media showing his tools what he's done commenting and encouraging other people and that's what we need we don't want people afraid to ask the dumb question we want people to embrace every question i agree with you uh i'm just so happy jason i can't believe we've never met before we actually have horse pads that matter hackers oh at one of their meetups i believe it was at one of those meetups tomorrow with the tacos yeah i know you're a big fan of this yeah those tacos were good the street tacos were really really good uh bear cool says how many times can you bend the material go for it you got to think about cycle testing for a real product out in the real world and there you go uh so it goes but i would imagine like the like that it's engineered to be able to withstand one million percent so ignoring this material we do a nozzle for vitamix and one of our rigid materials that's an abs like material it out cycled its injection mount injection molded counterpart by 1.5 million cycles 1.5 million there you go that's a lot like a lot like jason that's a lot live it's insane but i think the key here is why are we 3d printing what are we getting from this process so we want to design for it to take advantage of all those advantages yeah that makes sense when you would design for it then you can hit those specs that are advertised by all these oems and you can get into crazy cycling so uh engineer of all trades uh so through the youtube platform people can send in donations so 99 i'm gonna use that towards my coffee tomorrow nice not so bad but where do i send my resume now i would imagine you get questions like this a lot right all the time so if someone out there watching wanted to work at carbon yep or within the industrial additive field they could go to school for like mechanical engineering or some other other engineering trains but like if people want to know what's open is there is there job openings at carbon great question uh if you go to carbon3d.com there should be a careers tab and that'll bring you into our job portal and you can see all the available offerings uh you can connect with me on linkedin i always love conversations with people conversations really lead to where the resume doesn't show so yeah look on our job site on carbon3d.com and you know as far as how else to get exposure and get in shows like this are great you don't necessarily need to be an industry professional to attend a show like this this is an education you see bright minds walking around here the young kids being chauffeured around get involved local maker spaces which i'm sure most of your audiences are part of or have created themselves absolutely and then the community i can't say this enough unfortunately we all went through the pandemic together but i think you saw 3d printing really come together from the bottom up in community and really show what we can do together and learn from each other absolutely well one thing that's interesting you did people tell people to go to careers and see what's available and it could be one of you watching that's up here next to me instead of jason oh my god how would that be dude this has been amazing jason thank you so much i really thank you for the kind words and to all your viewers out there keep it up let's see what you guys can solve and thank you very much for having me have a good rest of rapping i'll leave my information with you once again thank you all right good show everybody bye jason how awesome was that okay so you all remember the ted talk from carbon where it was like print 10 times 100 times faster and everybody was just freaking out and that was a number of years ago but the technology has matured and they've done innovation and you saw it right here it's not just the really cool stuff that jason brought that fan shroud and that lumbar support for the backpack but just everything that's going on there uh like like i said in uh earlier we were going to be doing the booth visits tomorrow and i think that i'm gonna have to go say hi to carbon at least get a selfie at the carbon booth that sounds like fun keith tracy he was a super cool guy i agree super cool right in fact before uh we booked carbon here on the show originally originally i reached out to andrew sink because i've always wanted to meet andrew wonderful human works at carbon he said don't worry jason's got you covered and so it's like oh okay okay but man i don't mind having jason as a friend now that was great truetech this is the future tomorrow today literally everywhere you go here at the rapid tct show that is evident this is 100 the future today you it's crazy to think too because there's a lot of times uh people who know the consumer side of 3d printing when they talk about the quote-unquote future of 3d printing they don't necessarily know what's going on on the industrial side like at all these booths behind me and so when they see when when they see this it's life-changing because they've always thought in their heads that in the future additive can do this when now because of this show and what i'm able to show you it's already here the future's already here and people can already do this 3d musketeers got to get that selfie you know it okay absolutely chuck come here real quick real quick come on come on come on here we go come on all right here oh man look at that hey chuck so mike's right here so you gotta just make sure you're gonna talk there you go right there how you doing man i gotta stay real close like that i gotta i gotta stand on my heel my tippy toes chuck is local to michigan so uh it's easy for you to get down here oh yeah it's only about an hour right for me that sounds good to show up and see some friends see some people are you here for the night yes well then i think we might have to catch a drink later all right maybe some french fries or pizza [Laughter] no it sounds good that's good dude good to see you good to see you there's so many interesting things it's really a lot of really a lot here some of your guests and it's awesome and it's going to be a great show this is really the next step really for us to do the home printing absolutely come here and see what really can happen it's really amazing it's it's super amazing well i love it all right dude i got to bring someone else on come on oh hey bill i am ready for nate it's gonna be exciting here we look okay next up is nate i'm going to clear off my ipad come on up nate i take your hair man i like it when the yeah the hair goes yeah years of perfection here absolutely nate where are you hailing from uh i live outside of dc where you work mark forest mark forge yes sir you've seen mark forge before yes right oh absolutely yeah yeah and i see there are quite a variety of parts here i okay just right off the bat i'm just going to jump right in here right off the bat this is mark iv it's like this is what i think of when i think of mark force and i think of of tough parts with with an inlaid stronger material that really provides stiffness and rigidity yeah that's just right we're done right yeah okay and this looks like a like a brake handle of some sort yes that is a motorcycle brake lever so this is a very common uh demonstration piece that we have so that is a cutaway so that's a interrupted print um and we have the finished version here pricing so that one very likely has carbon fiber in it so very very strong it's a great trade show piece something people can put in their hands and really wrench on well people it's it's a familiar shape yeah and then people can feel oh this is real this feels good oh the weight is great you know that's that sort of thing but this is not gonna break really really strong yeah so the trade shows are great for us because you know our website's got information about carbon fiber there's a lot of buzz of carbon fiber in the industry but the continuous carbon fiber is really different so getting and that's that's the key continuous yes so getting those getting parts in people's hands and they feel it right that is that's the aha moment that we have with having customers oh absolutely well for most people out there who are watching this usually what happens is we get chopped carbon fiber so we get we get cf nylon or cfpla or whatever and it's just chopped carbon fiber to add some stiffness but a matte finish and it's it's never it doesn't make the part stronger whereas continuous carbon fiber adds an immense amount of strength to the part completely different scale of strength completely different scale yes yes so we've got the motorcycle brake lever yes what's next so let's uh let's talk this piece here so huge by the way is this one print this is absolutely one print done at the show uh overnight i actually think it was done overnight oh um so while everybody was dancing and drinking yes the machine was working absolutely so it was it was uh creating about 12 hours on our new flagship printer the fx20 12 hours may i absolutely it is beautiful uh service finish and really high speeds the machine is also capable of doing high temp materials for example ultim 9085 but this is our onyx material which is okay the chopped carbon fiber nylon that you're right kind of we were talking about earlier right so it gives it it gives it rigidity but if but but with the nylon so cf and nylon it's an interesting combination because if you do chop carbon fiber in nylon you still have that rigid or that strength of the nylon but that cf gives you that rigidity without sacrificing too much of that strength dimensional accuracy surface finish the nice matte color service finish meaning meaning what it the the outer surface after printing without finishing right yes yes okay because it's gorgeous yes these parts are not uh post-processed in any way um so you pulled this from the machine yes and it was done yes it looks gorgeous our friends at haddington dynamics they use mark ford's machine they do to make the skins of the robot and the pieces look otherworldly someone from toyota just chimed in and said they use it and they use it at toyota too yeah it's that the it's a a staple in all manufacturing facilities fx20 new machine yes tell me about it so it's bigger faster stronger hotter it was the buzzwords you just went all that punk on me there yeah get a good beat on there so um right it is our next generation composite machine it can do the onyx and continuous fiber like our current customers are familiar with it's that same experience but it's bringing it to high temperature materials yeah so that's something that's not being sized yes they're talking uh 500 by 400 by 400 millimeters so that's a pretty good size yes um what's the biggest high temp part you've printed you i have not printed one myself unfortunately i don't have the luxury of having this is a thousand pound machine i don't have one at my house i'm a remote employee um but i do have uh uh an uh x7 and a mark ii okay which are um you know more home friendly yeah yeah well actually a mark ii might be at my studio which might be it might be yeah so um this card is gorgeous nate yeah honestly yeah and this is you know keeping up with the um you know the the brand of mark forge is if people expect the best surface finish and we like to uh the best surface finish and dimensional accuracy right right because it's it's pretty well part of getting the best finish is going to be precise extrusion yes and it's it's so good dude so it's so so good look at this look at this we've got a great highlight video on on youtube where we've got a part in a you know really nice bright white light getting the you know nice reflection going across oh yeah you can see the the real perfection of it i would imagine okay so mark forge has a youtube channel yes okay yeah i think it's about behind the scenes uh perhaps i'll have to go i'll have to go find that okay so the fx20 amazing thousand pound machine is at your booth yes i'm gonna have to see that yeah obviously when i do some booth visits or or just look around i just want to go up to it like sometimes i just want to look at it man i want some time with it right okay that's cool can we move on to other parts let's do that okay so we've talked a lot about our composites um the strong uh and beautiful surface edge dimensional accuracy we got some we have some metal parts on here now so let's talk about some pure copper oh boy that is wait pure copper pure copper 100 this is copper yes and that is done on an extrusion-based printer so this is not a powder base or anything like that um it is done on a out of a spool of copper filament so i've i've printed with a copper pla whereas just uh the pla is impregnated with copper bits or and other metal bits that i've done it with but but copper okay copper filament isn't that just wire so it looks just like your your your abs your pla your nylon right we've spooled it up so we've taken that copper powder in the metal powder in general and combined with a binding agent a wax and a polymer so now we've got a that must look insane on a spool it it looks pretty neat yeah and you don't expect to pick up the spool and copper is very dense so you pick up right and it's very heavy oh so it's not a one kilogram spool of filament anymore this is not no um and it's extrusion so it's very simple to uh to use um if you're familiar with extrusion based printing fff i'm pretty familiar with that yeah so that's my that's my jam yeah it's it's easy to transition to um safe to handle easy to swap between different materials really so you get all the benefits of standard fff stuff where you're doing extrusion-based materials it's the same knowledge kind of platform so there's no new technology to really learn freaking copper yeah so does that mean other metals you can do this with absolutely so with that same kind of binding agent you can turn in uh inconel 625 okay uh a couple tools which is a super nickel alloy that's correct we had a guest earlier uh told us about got educated on it yeah all right very good um yeah uh stainless steel three different tool steels pure copper and an but inconel yes all from the same machine no no changing of hardware required so what's the extrusion temperature for something like this low temperature so we're not melting the metal we're only melting the binding agent so on the printer itself you still have to bake the part yes correct oh okay okay so you are you're making a green part right through extrusion yes oh okay so it's it's a low-ish temp yes yeah right we're not live centering um say the ice tail people were melting the the binding agent and the powder just kind of along for the ride as you create the geometry so then uh i'm sorry did i catch off nope well i had it so then if you're doing that to create the green part are there certain um things you have to take into consideration before printing like bridging or support material or all of that sort of thing yes so uh it's the same concept as the plastic printing with supports right there's there is support material needed for for overhangs so what we do is use that base material so if you're printing a copper part your supports are copper of course but we have a release layer of ceramic so that allows for you know ceramic yes so ceramic is very high temperature material so the sintering temperatures of these metals is much lower than ceramic so that metal that metal powder that's getting centered there's a ceramic powder in the separate second spool so that is not being centered and that creates a separation layer release layer so you don't have to machine away support i was just going to say uh typically on a metal part you'd have to like wire edm or cut or grind or whatever material off you're just it's not even attached at that point right so it's very easy the the part is that's so cool i know living this every day talking every day i guess i don't fully you know appreciate that do you have non-mark forge printers at home i do yes what do you have i've uh prusa mark ii okay and uh persevere okay so you printed in plastics yes pla and abs and yeah asa and petchey and whatever and you printed with supports i would imagine yes so you know the pain of not properly tuned supports and having to pick it off or cut it off or or accidentally getting a pla splinter those really suck so you know this yes i don't have any any any current scuffs on my fingers so yeah look i always look for the scars um but so then you know how amazing it is to have supports that just fall away okay so you're amazed i mean you talk about this every day yeah i would imagine and it could get kind of lost but if you step back and you're like oh yeah that's a huge differentiator for our technology that is really cool that is i would imagine when making end-use parts not having to take the time to uh mechanically remove the supports i would imagine saves hours yes or even days at this point right yeah so there's no additional hardware for even removing the part from the printer so you can get a part from print wash center with no additional machining or tooling and the parts can be ready to use right out of the furnace is this another one of them this is a pretty fun one so you probably uh it's a putter yeah i could tell yep now that's shiny and now does that shine just what you get on the build platform or is that polished that has been polished okay nice polish yes but look at that this is 100 percent 3d printed and there was support there right correct yep so that's the surface finish you can expect for a supported surface but that's not bad at all so you could actually smooth that out if you wanted to yes mechanically relatively easy all things considered yeah yeah i mean and once the part comes out of the furnace you can treat it like a it is a metal part but the surface finish on the rest of it is just glorious it's it's very similar to the service finish you see on plastic parts do golf i do not okay i don't either but i was just gonna ask have you used a 3d printed putter uh i have not but i'm sure someone has i think this is one of our application engineers who designed this and uh i'm sure took it out for uh for a good test run okay good and with additive you can play around with the internal structures and get weight where you want it and oh yeah especially putters seem very personal so the weight distribution of the putter across certain lines is important and people you know you have people at the golf store for hours trying them out so you can customize a putter customize a putter see that i love that idea right because we're talking about being able to use additive to make lighter better faster stronger parts for industries and and and uh and disciplines that just can already use it right like like we're not we're not redefining anything using additive to make a new putter right we're just utilizing what additive brings us to make a better putter exactly that's cool that's really cool um is that a bottle opener this is a bottle opener did you bring a bottle i did not oh it's true i was hoping you brought the beers all right what's with this these these are available at our booth they're a great uh small kind of example of what our metal print can do okay oh so this is a non this is the build plate yeah finish which is actually a build sheet so it's kind of a sheet yeah it's kind of i'm not exactly sure what it's made out of but okay when you say a like a baking sheet yeah yeah think of it like put it on a piece of parchment paper um but for metal yes okay so the uh the metallic printer has a heated bed and has a uh a vacuum table on it which holds the print sheet in place oh okay so that's important right there when you're done printing the vacuum turns up and the part peels off the the sheet with you know with minimal effort that's like cheating man okay so then i'm not familiar with metal printing as much as you obviously uh when printing a metal part are there are there any considerations that have to be made for warping so there is uh i guess you call shrinking so i guess shrinking because it's a powder as as the part gets washed and binded there's pores in there right that need to get close up so that centering process will shrink the part but fortunately our platform our slicing software compensates for that so your part is actually scaled up when it's printed so don't be alarmed when you print something like oh it seems a little big that's accounted for so when it comes out of the furnace it's as you intended and that's part of what makes it really uh usable like like production ready is that you don't you using it don't have to do the calculations for a part exactly in order for shrinkage you just say i need a part that's x and then and the software knows i need to make it x plus this in order for it to be x when it's done exactly so we're accurate we've figured all that out so a general statement to say is plus or minus one percent um so as the part gets larger um you lose a bit of accuracy um but that's continuously improving over time with software updates um our aggro platform includes printer management as well as all the slicer settings you need um so there's no additional tuning right the the printers just work um everything's dialed in for you um so yeah that's cool oh man i am nate this is the kind of stuff that blows my mind honestly right first time i was uh introduced to it same mind-blown really what what what's capable on on our 3d printers is amazing when i uh so printing pet g on a on a p a smooth pi sheet it's going to adhere to it really well sometimes you got to lick your hand and rub it on the build plate or use baby powder or hairspray or glue stick or whatever right and then you're still having to get it off and you're like no with this metal part you just you just peel it off it's that simple yeah oh man what's fun the machines are fine-tuned to print our materials yeah oh yeah purpose-built purpose bill well yeah and that's what you want right when you go towards a professional workflow you want to utilize an ecosystem right because you've got eiger you've got the machine and you've got the materials and so you can control the ecosystem and produce at that point the best quality part i know so in the consumer land a lot of people talk about open software open hardware open source like it makes a lot of sense but also in the professional world when you can control the ecosystem you you can make the best quality part and that's i mean that's what mark forge is doing right yes yeah so we can provide a guaranteed experience that way oh there we go there we go so i mean could i shove other material in the machine so maybe shove is the right word but you know what i mean if i wanted to utilize other material to do the mark for like the like the mark ii sure does it utilize so we've just uh so getting getting feedback from our customers we initially started out with carbon fiber nylon right really nice material great engineering grade material but that was the only thing that it could do um and we've released uh the ability to do pla for like low-cost prototyping um we're continuing to evaluate new materials for the line that's cool okay it's going to still bring that and and experience of it's been proven here's here's the pla that that we're providing to run through the machine and that makes a lot of sense yeah um but yeah i'm a huge fan of the open open open source uh community i think there's a uh a great place for that too and many at home right yeah and it's just different tools for different uh makes sense yeah okay well here one last question one last question okay one last question all right um if someone watching out there was interested and they have some experience um with you know ender threes or consumer level machines uh is is is that helpful towards getting a job it's a place like mark forged absolutely yes so um i'm an application engineer um and i had experience with 3d printers in industry and manufacturing and that was a great transition because right now i'm going around visiting customers and prospects and i get to see what they're making it's kind of like living how it's made which is really really cool so going to manufacturing facilities federal customers you know marines and navy shipyards and working with them to adopt additive in general um and also our technology in particular that's cool man well hey i hope everybody out there enjoyed it um go visit mark forge online and the youtube channel right behind the scenes stuff nate super good to meet you man yeah thank you very much nice to meet you all these amazing parts yeah good eye candy it's i mean that was pretty sick right there all right well oh thank you well have a good rest of rapid all right um i will uh i'm gonna stop by the booth all right well a little bit later you can you can use that later in your own personal free time well this means this means uh a bottle of something tasty is a business expense now because i have to try it out there you go that's the best way to do it i think all right hey take care nate have a good rest of rapping man well that was fun oh man how's everybody doing oh yeah i pet you uncapped on yeah everybody says pet giant captain i've been doing some uh printing at the farm in pet g i just did a 1200 part order for someone in pet g and i used hairspray as a release agent on smooth pei just because i had prusa build plates and so i didn't really have the option i had the smooth ones i didn't have the powder-coated pei um so i uh i utilized a lot of hairspray i utilized uh some some glue stick and so yeah everybody's telling me pet giant capped on tape i got i got to make that happen aerospace research meyerton stay hydrated so much talking i know all right everybody watching we are halfway through our stream at rapid tct i do have a bottle of water here but i'm inviting you to take a moment and grab whatever's next to you whether it's uh whether it's some water whether it's some coffee some tea whether it's an adult beverage heck whether it's kool-aid stay hydrated my friends hold rhythm mike wait we've also had joe prussia crash the stage we've had chuck hellebuck crash the stage hey colton okay here we go next up it's my good friend colton from stratasys joel nice to meet you hey nice to meet you sweet banana yo i brought two of me because i didn't really know like what this included if it's gonna be a high stress situation i figure two of me is better than one it's super high stress you can tell so there's a a 3d scanning truck called the scan truck in los angeles appropriately of course i start my interview by not talking about stratasys uh there's this truck in los angeles that is uh you don't don't touch my banana i i won't i won't touch your baby there's a truck of los angeles it has 200 dslr cameras one of those guys one of those kind of scan trucks yeah okay and at the same time it scans a person so it's a great way to show off what we can do with polygen printing at stratasys oh yeah because you're printing the negative space in the pockets right because of all those camera angles it really takes space in the pockets yeah i'm showing you throwing camera there you see his you see the pockets it's pretty good look at that yeah you're that looks a little chunky yeah well that's taking like my arm hair so if i like whacked it down any better right okay so triangulating based on my arm hair but then it's like a blender so that could use some work they said that if i was a celebrity they would you know spend a couple hours they spend a couple hours touching it out i would imagine so we just did it for fun so that's exactly that's awesome that is nice yeah like i have a i have a print of me but it's not i don't it's not polychromos i'll start making more of me so yeah if you ever make your way to la and go visit the scan truck i will print you really yeah david did you hear that okay we got to go to la to the scan truck yeah and hold up all right so we're in l.a they're right uh so we're in minneapolis but the scan truck for the scanning is right next to the airport in los angeles yeah i mean i'm in studio city so hey i fly back i'll stop by the track so their main thing and i'll print you joel will be jealous their main thing is actually driving the truck to uh film student film areas and then scanning actors as well that makes a lot of sense that makes a lot of sense so that shows figurines or we can do with color right let's go i i am going to lay you down just because i don't want you to fall over and it would be bad we can also do semi-transparent colors so this is showing industrial design process designers so when you're designing a product if you can look at something that's just an fdm single color print or you can show your stakeholders this it looks like you're ahead of the game even more than you actually are ai yes oh this is okay liquid inside is printed too well this is cool so so the the outer shell of this cup is transparent yes so then so then you get you're seeing the inside color through the material which really gives you a better real world experience if you're prototyping something and you can like you said if you were to print the red in here or if you put the red in here and it's transparent this is this is much more indicative of what the end product is going to look like yes we could do some that are empty as well and pour liquid inside yeah the top here uh it comes out low matte so i put some epoxy on the top just kind of move it around let it sit overnight and then as clear as glass this is cool like the colors are vibrant yes it's not usually in in um in the consumer level 3d printing if you're doing fff or filament-based stuff you know you'll sand it you'll get it smooth you might hit it with a gloss coat and then it looks glossy shiny pretty very sparkly whatever you want to use but this is already there right it's nice so this was sand and polish on the outside okay yeah but still we could but we're not adding any color right we could print it with this side gloss coming out of the printer so the top can be glossed the bottom is always matte so what i like to do is print this cup like this so this is gloss put epoxy on the top which is like five minutes of post-processing and you're done oh that's so cool it gives you a high value model really cool like just being able to reproduce it looks like photographic color yes and we can go right from keystone so so keyshot is a rendering program used by industrial designers keyshot or keyshot okay use my industrial designers we now have a workflow you can go from your render where you already did all this work of color and then export and print on our printers and it'll come out with all that color and material data so in keyshot i would imagine they're using a known color values for things and so you can take that data wraps on the outside yeah apply it oh it's it is a it is a design tool yes okay so you can take the software package they're using and print from that rather than having to export to an intermediate file format so instead of uh applying so nice render and then a different process for apply colors prints it is one process yeah yeah so our colors are getting a little bit better and this one's fun because i'll hand it to people at stratasys and they know we can print bananas so they're very unimpressed i'm like oh look i printed this banana did you print it oh it's like and then they say something like that like like it feels different like it feels like a banana it does it's soft i had something a banana banana someone yesterday in the booth was looking at all the rigid parts he picked that up he's like oh that's actually a banana he put it back down and then he looked at the other ones it's it was the best this is like i do this and it it's like it remembers the this is weird colton this is okay what's happening here this is agile's color so we've had agilis a soft uh apologetic material for a while but it's only been in black white clear so now we have cyan magenta yellow so just like we print this out we can print out the whole model but wait a minute he's real like his ears flex you can pick his nose and try it yeah it'll go back and forth but oh man this material is crazy yeah it's neat toy design really yeah so the the support material for polyjet is jello like in consistency okay so we're doing with this is we print the short 30a material on the outside for a certain thickness so we can specify that thickness different on this print than this print whatever we want okay and then the jello like material inside and that'll make it a little softer so that's why there's actually two different shore hardnesses here like there is a flash and an internal sometime i will print uh a banana flesh nested inside of the banana peel and then i can peel it open right when we get that's just showing i'll do stuff like that yeah yeah what is this so this is the same thing this is actually a file we got from turbosquid uh his name is mike we've renamed him ageless andy because that's the name that makes sense yeah yeah yeah uh so he is soft there's uh three millimeters evangelist supports and then a rigid skeleton on the inside so he doesn't just fall over or these 3d printers they are i have uh a bunch of glasses at the booth so people can take selfies with them and wear the same glasses he is but yeah actually needs something that's really neat yeah i need some new senses let's see if they here while we're here that's not you're doing great let's uh take this out and i'm going to take this photo i can swap this around and uh you're just going to you're going to go right here with me perfect i've always wanted to get a what this is cool this is cool he's in film industry right thinking why would imagine yes well anytime you can make animatronics you can make like film industry or entertainment industry anything if you make props that aren't just hard as a brick right you have some give to them it's safer for the actors it's safer for the crew and so you get now you get accurate color great detail and safe and we could even so these ones look like they should be soft we could even print out parts that have a gray skill on them it's like a chrome reflective kind of baked onto it so it looks like it's hardware to soft so that what you mentioned is a cool application for printing things that should not be soft but are for safety reasons when we when we talk about like space guns right in and sci-fi yeah those have to be made with um either eva foam usually or or something where there's there's there's craft work going into making these and then putting on a shiny coat just making sure they're safe artistry like you could they could and sometimes you have to make hundreds or thousands of them and it takes a lot of time so you've now sped up that process you've made it safe and you're giving accurate color chrome finish great detail it reminds me of a story from leica like as a film producer they made cooper on the two strings missing yeah they're based out of uh portland portland oregon they print on our printers with origin actually with rigid and soft materials and they do replacement animation really cool stuff so this every frame of that oh that's right with like different mouths and eyes yeah yeah so the conversation early on was with this character coraline she has some freckles well how many freckles can we put on coraline's face every extra freckle is one more time an artist needs to put a freckle on right so that makes scalability really hard yeah but now when you can print with color she can have whatever whatever freckles the designers need that's cool right so that's that scalability factor right yeah and repeatability so that one's neat the uh the one that i'm always excited about is actually printing on fabric we can take the same technology we can put a piece of fabric into the printer and then we can jet that liquid resin onto the fabric yeah i'm going to put that over there because i want it that thing is going to disappear because david's all over it he's talked about it like three or four times now yeah you know you know when you walk by the booth you look at something he does this he does and then it's gone well not yet but you know if the show's over thursday night and you guys don't have it in your trailer i don't know anything no i don't i want to ask you now printing on fabric we can put fabric into the printer and then adjust the liquid resin just like our normal process it has enough time as a liquid to wrap around the fibers and then it cures into a solid using the uv lights okay so this is huge in the fashion industry it started in europe because they've had access to it for a little longer so there are some runway dresses that are totally 3d printed on fabric so colton i know there's a guy by the name of david shorey who sort of pioneered 3d printing on fabric with fff plastics and he would he made he would do he would get a piece of fabric and do dragon scales so that they could rest you see that okay cool but this is the next level with color with color and just the detail here is extraordinary so the resolution on a printer like this is 300 by 600 dpi right so you can make you measure it like like a laserjet sort of dpia we're using similar technology as printing on on paper right or jetting out liquid you look good thanks so here's another one that's uh a lenticular effect oh you want to here let's show that that lenticular effect has two colors on the base and then as you move it uh a clear dome on the top is going to magnify one side or the other that's why it's different colors right okay so but that's just one so i've heard the term lenticular before it's the same thing used in children's bookmarks you get for 25 cents right right but this is down to the coolest level this is when like i understand what that means now when someone says lenticular clothing i'm like okay and you can see if you hold this up like there you can see the two colors on the base yeah and then the clear dome that's yeah so that's how that's why it's changing color so on a model dress this is a section of a dress right you know the whole dress is changing color as she walks by you it's very cool exactly doesn't need to be lenticular you can design whatever you want and there doesn't even need to be round shapes so this one's kind of fun because it it changes did you just appearance in a different way it looks like you built you printed a like a squoosh ball onto fabric right oh and it's rigid material it is oh but it feels soft because we're printing on a flex style uh flexible something wait a minute wait a minute wait wait wait wait wait and it's pretty durable wait but it's like a topographical map it is like there's there's there's a height map here it's another great application so again starting in the fashion industry but i see this going into costume design for movies animatronics uh automotive looking at designing for sportswear or you know sporting goods um shoes uppers print on shoe uppers for limited edition kind of partnering with a celebrity type thing oh absolutely you could make some incredible custom things yes uh but but the lenticular side of stuff that blows my mind like being able to and we can do that with rigid models too there are some researchers that i believe it was mit they wrote a white paper on how to print lenticular with polyjet based on a refractive index and they have some rigid parts uh that aren't you see the colors there too that's so this is cold this is really cool man like i said for show and tell show me cool stuff and tell me about cool stuff like you've done it no way what i thought that would be oh wait look so i asked david i said hey send me some logos we can do something cool what did you do i mean i know how you did this but how did you do this usually you'll make this in procedural programming languages so adobe substance you can do um grasshopper in rhino okay houdini um 3ds max oh that okay that kind of stuff yeah this one specifically i wrote a program in c sharp that just takes in an image and then i can tell it i want my things to be this big and this spacing and and this height and then it changes the height based on brightness whatever so that's a program i'm working on deploying out for our customers to use okay there's other programs you can do a lot more with but this is so this is grasshopper that was a few seconds after i have the program in hand that's it yeah jeez it's fun but this is this is game changing for 3d printing on clothing type of stuff because because this sort of finish here like it doesn't even have to be that tall you can make these half the height you can do whatever but to have like like think about it you have those um those those uh jackets or jerseys with sports logos that are raised or names that are raised or like i imagine popular theme parks that had different outfits for their workers or the the cast members as you will like it's done in a way that you could not traditionally manufacture it right either based on the shape or the change in color or you could have uh clear elements and then color inside of it so it'd look kind of like a gem effect to it would be cool so then a stratasys gonna be my next merch provider is that what's happening that'd be a cool deal oh man do i get to keep this yeah that's for you i have uh i've been printed on the sheer fabric as well as one of those so that is a spandex material okay this is jersey it's been a while since i've worn spandex but i recognize that i remember it most most fabrics work just fine um vinyl and leather are kind of tough because there's not much for it to hold on to but about everything else works great this feels like um you know people here i'll show the mesh um you know the people that make custom rugs people get the rug guns and and they do the things and they have to shave it and stuff this looks like a highly detailed version of of like someone who makes a custom rug yes but but with different heights yep that's crazy yep it'd be tough to do that because with the rug gun you're gonna trim it off afterwards and you're all going the same height yeah very height based on it so the machine that does this is a is called what so this is printed with polyjet technology okay you can print it on a fabrics uh printer or a textile printer textile i love the name i think it's uh just genius name so text style tech as a technology style as in you know text style and then textile is like fabric yeah absolutely so putting all that together the textile printer is one that can make this okay it's based on the j850 which should print seven different model materials at a time and polyjet means it's it's jetting the material out real fast real small yes fast uh so we have over 1500 nozzles i like to say that fff or fdm printers have two nozzles apologetic printers at 1500 nozzles uh but yeah so it's bringing seven different model materials end of support material uh each one each material has 192 nozzles oh i see so you can be as precise with what you need to lay down yeah okay yep so do you inject the material just where it needs it and then uv light will cure everything into a solid oh okay so then what are there certain considerations you have to take in when doing something like this because so is it considered a green part before curing uh so there's no post process this is exactly how it comes out of the machine it does not need extra uv light we do put an oven afterwards uh and here it doesn't go yes i see okay okay i just want to make sure i understood that it brings layers down to about 14 microns usually you do 27 it's a good bounce stream speed and different quality but yes it's going to cure each layer uh as it prints so my my usual printing in fff land of okay thank you not measured in my crumbs well it's 0.2 millimeters so that's 200 200 micron okay and usually when i want to do super high detailed on a resin printer i might like 50 micron so then half again half again yeah you can get down to what this printer can do you have fun with this don't you it's a blast what are you doing okay what do you have at home do you have printers at home i do not have printers at home zero non-zilch no okay so growing up i was in a robotics program so actually first robotics yes oh okay uh i was at the world championship a couple weeks ago had a blast there we actually had a we had a stratus booth at the the um at the first robotics championship in houston okay and my favorite part is all these full color parts and someone will say is this printed yes is that printed yeah that's not printed yeah it is it was it was a blast what does stratasys do for first robotics so if i think of stratasys i think of i mean i like the type of things you've shown me so when i think of robotics i think a very purpose-built like 90 degree angle sort of so because we have five technologies now we have uh fdm polyjet staff uh p3 and stereothorography those such a lot of robotics needs most of the parts i print for robot teams are out of fdm principles okay so i work specifically with polyjet i have a background fdm right that's how we sponsor teams this year we donated 50 printers two robotics teams uh the first robot teams so that's how we got our sponsorship for this year uh previously for the last uh eight nine years we have been sponsoring first tech challenge in minnesota just with a partnership there so first robotics is actually made of four or five competitions first year box optician is for high school kids uh refrigerator size robots right first tech challenge is middle school high school smaller robots 18 inch cubes it's much more scalable higher team smaller cost but they can still use 3d printed parts and then you have first lego league which is elementary middle school that's where i started uh mass building robots of lego mindstorms so down to third grade and then before so still well simple machines mindstorms is crazy yeah obviously you said majority but yeah but so then that's where you started yeah what did you do with mindstorm uh my first introduction to it was actually with the rcx which is a yellow brick and that was with the first box competition so in there for that competition you have a four foot by eight foot table and there's missions on the table you need to program a robot to start in the corner of the table and go out and it's either delivering things manipulating things or bringing things back oh and the robot has to be autonomous right and it has two and a half minutes you can send it out it can come back you can reconfigure do it again right but you have two and a half minutes to do all your your missions that you've been programming for the last few months oh so oh i see so so so what i know we're not off the topic of stratus is here but but that that's really interesting so then for the the first tech challenge or the first the first lego league or whatever the legal league right first tech challenge is one that we print a lot of parts for that's right so then the first robotics teams we donated printers to and then the what where you started was lego league yeah elementary school so for mindstorms then which i know a lot of people 3d print lego compatible bricks i would imagine you could do some crazy lego like lego compatible bricks doing anyway with power graphics on them but you said programming for months and so it's so you are essentially building a robot and just writing the software yes wow so you're given the missions and you you set up in your basement right as a team make sense for the school and then start designing your robot okay what are you going to use for manipulators for this and then program it test it try it again oh it's just over you're just i mean you're essentially it's a workflow it's a life cycle yeah like we're teaching students how to use engineering cycle of you know figure out what went wrong and go back tweak something this was cool man i'm i'm shocked i'm honestly shocked like this you know you you have i have this here show and telling i tell people to bring cool stuff and show it to me and tell me about it but like this is kind of mind-blowing it is it's neat it's the lenticular stuff i just like i want this on my car that would be amazing automotive is interested in i would imagine adopting that technology luxury automobiles joel thank you nice to meet you it's so good to meet you i'll leave those with you i appreciate it i'm taking me with me yeah you should you should probably take you uh but but you've left gifts do you want a banana you keep bananas you really yeah okay that one's fun for a different reason it's just weird it's it's feel that oh no feel it like bend it it has a memory to it oh okay well keep it though apparently we have a banana now thank you jill thank you cold good to meet you man well that's right an actual 3d printed banana for scale hey everybody banana is a weapon of choice that is true karen that is very very true oh aaron the uh the um the stratasys truck is in portland right now so you can there's the stratasys experience it's a truck that travels around if you're in the portland oregon area right now you can actually go to it i believe brian vines nobody mentioned that david still has that disembodied head it's prison mike uh that was amazing cool banana bananas what i can answer your cut-ins from guess what that was super cool tool yes that was that was amazing i knew that good to meet you colton i knew that uh stratasys was going to bring amazing things and i knew that i was told lenticular clothing and when i was told that term it was like sure i know what the word lenticular means and i know what the word clothing means but i i had no idea of what it meant when you put those two words together and obviously you got to see that was insane like that looked insane it was tiny tiny little lenses showcasing colors from different angles this is slate okay so next up next up next up is slade added what additive metal additive big metal additive big metal attitude that's that's saying a lot and we also just won the award for innovation they're which are sharp edges on it very sharp edges and it's super heavy the sme is okay so what's coming up next is industrialization sharp heavy and metal okay and this is also the winner of the and the sme industrial achievement award oh no did i get that right sweet well come on slade this is heavy yeah it looks well and you're wearing the gloves to keep you from getting oh my gosh what'd you do i don't i want to help but i also want to keep my limbs good choice is it in the way no it can't fall off because it's a hundred and twelve pounds and it'll hurt your foot sure foot leg stage floor like take your pick man okay so what is it nicely good to meet you so i would imagine it's big and it's metallic and it looks to be 3d printed yes and it's like i would imagine this is something that can hold pressure or a vacuum it can hold both okay it is meant to keep things dry at the bottom of the ocean it's a pressure vessel for a uuv unmanned underwater vehicle oh oh oh oh okay so obviously bottom of the ocean uh lots of pressure lots lots of like how many atmospheres this thing has been tested to 1040 psi which is i don't know how many atmospheres well i don't know i i pump my body to 35 psi yeah yeah that's insane a thousand psi a thousand a thousand thousand psi now you said it's to keep the unmanned underwater vehicles dry well you put all your heart all your electronics inside this pressure vessel and so you keep your computer and your batteries oh okay and then you float this uv uh you swim it through the ocean so how does that okay here's a good question then if this is a pressure vessel yeah and you have components inside how do you get out okay if a battery's in here and a motor is out here how does that work it's not a dumb car it's not a dumb question okay and we're all new to uuvs we know additive manufacturing but we learned we went up this learning curve on uuvs so they have if you're a uuv expert you have super standard ways of getting cables in and out oh so that's a solved problem it's a solved problem okay cool but the the problem that we were solving is right now to get a pressure vessel this is 12.75 inches in diameter it's huge there are standard sizes i did not bring any of our 21 inch diameter because i'm not that strong probably break the table at this point or you or me yeah so the problem we were solving is it takes six months to get one of these made typically typically why so long because it either comes from a forging oh okay or you machine it from a billet i mean the walls on these things are an inch thick an inch thick of metal and it takes a long time just to get it's a supply chain problem it's this supply chain problem that has been creeping up on us now it's kicking us in the face right yeah oh i understand so forgings billets even castings are long lead time items we can make it in two weeks so do you want it in six months or do you want it in two weeks and are there any trade-offs for the speed at which you can make it with additive there are trade-offs it depends what diameter you're talking about because there's standard billet sizes that you can buy and so a standard billet uh is going to be more cost competitive so basically if you make this out of billet we can get it to you 93 faster but we're seven hundred dollars more seven hundred dollars at that point that is a that's that's that's pennies it's a push okay it's a push so but that's the trade that's the kind of trade that you're going to make so now sme innovation award is that right industrial achievement industrial achievement i knew i'd get some of the words right i hope you don't hate me right i don't i i'm just thrilled to get the award and why why was this what about this made it award-winning well the award was for uh career achievement so i've been involved in additive manufacturing my whole career i've had impacts in a lot of additive uh materials and processes applications and developments i'm glad you're here i'm glad to be here uh so the award was really the selection committee used a wide variety of criteria to select the winner and it included impact on the industry it included the outreach the educational impact the involvement with the community and the sme community and so all of those things were contributing factors um the technical achievement was probably one of the larger components of that and so okay i've had impact on bringing metal additive manufacturing into spacecraft when i was at lockheed martin i produced the first additive manufactured titanium propellant tank you're kind of seeing a theme here i've been working in pressure vessels and tanks yeah i see a lot well it just means you get really good at it we are getting good at it i mean to get to a thousand psi hydrostatic pressure and pass not only does that be structurally sound but you can't have one single pinhole in this whole thing now that's a challenge and walk around the building and ask someone to make a vessel they can go to 1000 psi with no pin holes and they might not sign up to the challenge so no pin holes meaning no no no no no no passageway okay no passageway at all not even micron size and so you this is once this is sealed it is a homogeneous container it is perfectly sealed and that is a huge challenge people don't realize how big that challenge is until you try it well if you know sometimes if i want to save leftovers i put it in the little seal a meal and i get what i believe to be a perfect seal at the time and you know i put in the fridge and the next day it it's still fine but again my sandwich isn't spending time at the bottom of the ocean right which is where i would probably would probably spoil but if i put it here it'd be fine it'd be fine a thousand a that's a lot of atmospheres so then technology like this what you're able to do without a pinhole without any any way in i would imagine is important for the future of space travel oh yeah absolutely because the other thing that i didn't bring i wanted to bring this but the thing that i didn't bring is a cryogenic tank we're making a cryo tank for nasa okay cryo meaning holding uh liquid nitrogen liquid oxygen oxygen it holds liquid oxygen so it's a tank but we built all of these cooling passages right in the wall oh so you can pass the cryogenic fluid all around the outside of the tank you can keep the oxygen as a liquid that cryofluid that's circulating around because it's completely sealed completely sealed so you you don't lose any of that cryofluid you don't lose any of it and so this the one we're the one we're working on right now is designed for a lunar mission so it's going to be on the moon okay and it's going to keep oxygen in a liquid state until we're ready to use it so that's going to enable human habitation right in space and on the moon uh but we're building this tank this tank is awesome it's got thin walls how thin three millimeters oh thin that's that's really thin it's machined inside and outside okay and we're machining inside the passageways of all oh wait wait wait the passageways for the cryofluid is within that three millimeter wall well the wall kind of wraps around the passageways it's such a killer design it's that's cool crazy and so it comes off the table fully finished you don't even know it was an additive part because we've touched every single surface with uh a ball mill wait what with a with a ball mill oh a ball okay yeah yeah so we haven't even talked about big metal additive and what we do but no you have it but this has been fun so far well i'll tell you about the ball mill if you want to hear about the ball i do want to hear about the ball mill okay our process is metal additive but it's hybrid okay big metal additives big metal additive okay but it's a hybrid process it is so big metal added to being the company your company yes sir okay and this this process you have for doing additive metal is a hybrid process yes okay i'm following i'm with you our work table is six foot by 12 foot [Laughter] so if you want to make a sports car chassis we can build yes you can in one piece uh and we have multi-axis metal deposition fully articulated and oh multi-axis cnc machining fully articulated with a tool changer so i can grab an end mill or a ball mill or a chamfer mill on the same work table on the same work table so you can can you can you can do an added process and a subtractive process at the same time or essentially with i mean just like that right just like that that so what i've learned because i've done uh i've showcased a machine that had a much smaller build plate but it had the tool changer and it could do additive and subtractive yeah and one of the benefits of that was material savings because the additive could just over print a little bit and then the subtractive process finishes it to a cnc sort of spec is that am i on the same but you're doing it at six foot by twelve we're doing it six foot by twelve foot and we've got one more benefit okay every layer of metal that we deposit comes down as a big bead of metal right and you are melting we're melting wire okay a wire feed edm uh wire fed arc arc okay so we're putting metal down big fat big fat big fat beads of metal with a very well accepted manufacturing process of arc deposition and then after the layer has been deposited we get the end mill and we just barely clean up the surface we graze the top of that bead think of that rounded bead we cut that rounded top off we are always putting metal down on a clean flat surface right always and because you're you're you're milling it away you know precisely exactly where that flat surface is oh yeah so that's how you could that's how you could make it perfect that's how we make it perfect now that's that's great it's perfect in three ways three ways three ways it's perfect because the metal diffusion if you talk to a welder and say what's the best substrate for metal deposition they'll say a freshly machined surface okay so it's perfect for mechanical properties it's perfect for dimensional properties because we're constantly trimming the part constantly okay we're removing all the excess all the over build all the starts and stops all the anytime a nc machine changes direction there's a rapid deceleration and acceleration that people don't kill for a little bit a little bit and it changes the height ever so slightly but we trim our material so we're the only additive manufacturing process that i know of where we actually know what our layer height is because we cut it there yeah because it's precisely that layer height that gives us dimensional tolerance we don't get stack up of over build or under build that's really interesting so when the part okay so when when you've built on your 6x8 or 6x12 table your metal part it's done i mean it's it's it's done it's done it's done it's done now this part we re-fixture on the table twice but we do all those operations we do all the machining we do all the milling we have o-ring grooves in this surface and in this mating surface we do all of our own o-ring machining on the part on the machine it comes off like that so it's red i mean it's just ready it's it's ready to rock that's really cool the third hidden benefit of that machining operation we get isotropic material performance everyone's worried about anisotropy in additive parts well that's the the stresses on the material material not being a regular conformity right not not being the same in all directions everyone says oh there's layers here so the tensile strength is going to be the worse in this direction doesn't happen for us because we have a freshly machined surface we remove all the oxide all the scale all the debris all the non-conformance and it's gone so we have that every layer every layer okay now i have to ask why don't other people do this let's go ask them i don't know i don't know i've been so busy doing this i don't know why i mean the audience is freaking out i'm sure i'm sure they're freaking out so so part of this like when we talk about the um on the on the consumer ff side just bear with me for a second here when we talk about the the deposition of the material it's coming out of a round orifice the nozzle so anytime you need to make a corner it's not really a corner or if you're making layers they're having to squish down on top of another and it's relying on the previous layer to be perfect or to squish down i mean you can make some really nice looking parts but they're not perfect and i and i get that and like that process is amazing and especially if you're doing the subtractive part the milling part as you're doing the additive process you can have parts of the model that you're building enclosed oh yeah but milled inside yeah yeah now here's another thing you just giggle at night every once in a while oh i no because i don't go home i just stay at work i like to be around the machines i mean do they make a nice hum that's just comforting they do well i guess when they're milling they make a knife sometimes a part like this it's like a really nice baritone sound it's just like being home i mean i love what we do i think everyone at work loves what we do and imagine it seems next generation it's fun we're just trying to solve manufacturing problems we want manufacturing back in the u.s we want it to be cool we want people to want to do it we want to offer freedom and flexibility creativity but really we want to solve problems of lead time of cost of design complexity and we want our customers to understand how to harness this kind of capability to solve problems makes sense for this it's a lead time problem we just got finished making a satellite demonstration for the air force and this thing is so cool so you had me at satellite demonstration well i worked at lockheed martin space yeah i get it i get it i know a thing or two about satellites and how complicated they are and sort of what the hidden problems are the hip problem of satellite assembly is the fact that you have to put this thing together and take it apart so many times every time it goes in a thermal vacuum chamber for test they identify some problem with signal or latency communications power something something okay they have to disassemble the satellite dig down find the box open the box find the board find the transistor whatever it is adjust the whatever put it back together this is people in bunny suits in clean rooms it's long time consuming labor intensive so here's what we did we said okay let's take a satellite let's take all the components of a satellite let's configure them in 3d free space floating exactly where we want them to be let's get the cable lengths exactly where we want them let's make it so we can touch every fastener on every box clear line of sight then let's use topology optimization to grow the chassis around all that stuff no so i can we've got two of these satellites in our shop i can walk up the satellite you can tell me which box to pull off i can do it without disturbing anything else now what does that do to assembly time well that's that greatly reduces the time for everything because you're you're it's you've essentially made it modular but but topology optimized modular that's what's so cool is we use topology optimization to solve another problem right assembly that's so cool it's fun we have fun all right you dude okay i got i got to say thank you for stopping by thank you for having me well first of all it's really good to meet you and congratulations again thank you uh but but like the level of insane that this is isn't quite comprehensible on paper right it requires you and your smile and your words to come here and assault me with it metaphorically speaking yeah yeah it didn't fall on either one of our toes not yet day's not over yeah i'm gonna get the gloves back on just because there's still some machined edges so while you're doing that i'm gonna see if anybody's got something to say oh yeah i'm being i'm being careful desktop what desktop okay so let's see valerie said elon should buy your stuff instead of twitter there you go it's coming down uh a guy by the name of robert robert reagan my buddy that works for spacex and now as a project manager for starlink really opened my eyes about how much of a challenge cooling in space is so i guess you're solving that we might this table has history sorry about that oh it's fine someone by the name of keith once he said liquid oxygen i knew he was a super cool guy [Laughter] you're going to hear some grunting as slade takes that back to the duffel it's essentially a duffel bag there's a a pressure vessel that can hold a thousand psi and it's just in a gym bag that you you take and put your dirty gym socks in that's amazing that's literally amazing time to hydrate aerospace research scars of honor that's right this table has honor right here oh how's everybody doing we still have more than a half hour left of incredible stuff from the floor here at rapid tct and i'm excited to bring it to you uh oh there's a buffet table next to me but no food dang it oh lift with your legs not your backs laid [Laughter] oh imagination what company was he with again big big slight big metal additive big metal additive that was slayed from big metal additive stickers oh these are cool stickers man there we go big metal additive [Laughter] hey slade there are a few things more badass than carrying a 1000 psi capable pressure vessel in your duffel bag that is that is amazing are we oh we are good this oh my gosh what's everybody's name what jonah right ethan got it next up my best friend in the world ethan coming up from desktop metal come on up man joel make sure you're hydrated you good i've been hydrating all day how are you doing man thanks for having me good to meet you thanks for everything you do for the industry just let me just uh in general clear the table for you oh glad you man thanks for coming on it's really exciting because well i mean you're at a booth you kind of understand what goes on in the booth but to really get the word out and to really inspire people yeah show them cool stuff and you tell them all about it it's the funnest thing to do it really is i first got to present you with we are in detroit here so i gotta present you with a 313 detroit ring got the sky the skyline is in there yeah absolutely been wearing these all week so now you can wear one with me we can ring cheers just like that just like that there we go perfect all right i love that i am um i just don't want to swell up and then have it so i have to you have to cut it off so maybe i might be figuring you know maybe make a necklace i have a couple kids okay three of them in fact and uh maybe one of them shows their kids their friends at school fair enough i love it so this is mine it's your super mine it's yours to do whatever you please you're a kind sir i do my best what else you got all right we got lots first we got some elastomers so large motor mount okay printed in top down dlp top down okay like dlp like dlp but you know projectors are above got it okay that is actually you know the plate is actually moving down into the vat of material what advantages does that offer well much larger build size we're actually able to array projectors because with dlp right the bigger your build volume gets often you're sacrificing resolution right you only have so many pixels with top down we actually are arranging multiple projectors on top of the build so we can have these very large builds while maintaining a small pixel size oh so we can do these kind of builds do please do what's so cool about this is this is a new uh era of materials so good yeah it's called dara chain dura dura chain is this new dura chain brand of materials we have it's photopolymerization induced phase separation i've been practicing that all day i was gonna imagine okay photo photopolymer induced phase separation what is phase photopolymer means it cures via uv phase separation is what is so cool about this material is that when it's illuminated with light at a nano level the material actually splits into two different materials like vinegar and oil like vinegar and water separates like really separate at a nano level that allows those materials to polymerize differently into hard nodes and soft bridges between those hard nodes which is a you know when desktop metal first acquired envision tech i had this stigma of resonance as being brittle you know you drop it it shatters kind of kind of sure well lots of people have that yes it's come a long way this is incredibly tough durable materials now well when you said motor mount it's like you have to you get a really good idea yeah just the stresses that this part would have so that's what's so exciting about the you know the that polymerization world and the dlp world is just these advances in materials that's really unlocking the nano level it's just a bunch of little it's almost like a net like i was just going to say it's a big solution but at a microscopic level between hard nodes and soft nodes so you get that toughness that rigidness but you're also getting you know what the hell it's tough i was hitting a table no i can do it because it's uh it's dirt changing so this is what it's made for chain is going to have a lot of applications that we're really excited about already is foam so this is the new free foam from foam foam foam foam so same dura chain technology photo pips but now we put a foaming agent hips total pips okay i heard a couple glasses at the end and i i thought that was an interesting one oh yeah okay we can do a bunch of separations like yeah pips so photo pips with this we add a foaming agent we print it to the dura chain to the dura chain okay we print it at this scale this gets fed into an oven 2 to 7x expansion this expands into this that foaming this becomes that yes that foaming agent is it has gas in it it expands like a piece of popcorn and pops into this so you still you still get the the mechanical properties of so they're fundamentally different relatively different materials but very tough foams yeah i mean this is a true foam oh what's so exciting about this too is that you know we can you know with traditional foams you have to actually change material right to change properties here we can have architecture materials where we can change lattice structures and dramatically change the performance of the part right right utilizing the the mechanical property property the mechanical properties of the material you can now change like the structural bits yeah to take advantage we're staying in a digital world that is where you can imagine you when you're buying your car seat you can pick from soft to very soft to very really you can pick the sections that you once saw absolutely so this is the digital foam it is digital foam uh it's going to have a wide variety of applications it's just comfortable it is i've been sitting on it all day you know talking a lot of people in the booth on my feet all day sometimes i got to pull this down and sit on it like i would imagine you could have a 3d printed chair absolutely and this would be cushions helmets shoes padding oh yeah there's a lot of applications for this so now because you understand the rate of expansion you probably have that dialed in it's very it's very repeatable it's very accurate so helmets though it's not just making a better foam case for a helmet it's it's actually pinpointing the places where more coverage is needed or a denser foam it's really interesting right because on the metal side of things we center and things shrink right we go from bigger to smaller in the final part state here we're going from smaller to bigger so we're actually utilizing more of the printable area of the printer because we print things that are smaller but then expand to our final product it's crazy well and especially because it is a determined expansion absolutely sustainable determinant so then you've just increased your your volume print volume by 7x yep so it's really cool you see it happen with the shoes where it looks like a babydoll shoe and all of a sudden it's a men's 10 and a half that's funny it's you know it's like a conveyor belt system with the heating like you would do a pizza it's a very very cool very very quick process but this feels good it feels great and it's it's tough it is a tough material i do see a rip over here something might have happened maybe someone came through ripped it but it's tough material show floors are tough show floors are tough but this is tough but this feels gonna be launching commercially uh next year so really so we'll actually see this in product on shelves yes absolutely i'll be able to buy my 3d printed we'll keep going oh okay moving over to metal i had to bring you a dragon oh that is guy beer's dragon printed all together biter jet we're here let's take these actually i'm gonna move that so over 40 pieces all printed together which is too cool not to show you so macgyver his name is uh he's a friend of mine and he designed this yeah and this is amazing very very cool amazing it i'm sure you've seen many polymer versions as have i but etsy shop i sell a lot of polymer versus really just feels you know and of course oh my god what's incredible about this is we actually printed it all coiled up and then on its center plate and then centered it all together right because you know they're a sintering process and came out all together and of course you know this is well it's you know this is a dragon there are industrial applications for this as well we're looking at with customers where this ability to print in place assemblies is really beneficial for you know a variety of reasons right anytime you can you can create the metal parts that are already assembled like you've said absolutely energy assembly everything logistics so how long does it take to do this dragon souls this is put it on the shop's printer you could print the what wait the what runner the decimal shot printer with the shop okay so it's binder jet technology so the actual jetting process you know if you would you put many of them into a build you could probably put 10 or 15 or 20 of these in a build that would run in eight hours you then would d-powder and sinter in 24 hours and you'd have you know eight or ten of these but of course while you're centering you're printing more so you could print a couple hundred of these a week that's part of why the shop system exists for that continuous you're producing hundreds of parts a day so high volume this is crazy yeah like i yeah like i um the reason i opened my etsy shop and i started my print farm is because i was i have the commercial license to sell a lot of these different models that are articulated sure this is the only metal dragon i've ever seen look at that ever history people all right this has been a fun one oh yeah this is this is amazing yeah i would i was gonna say the problem is but it's not really a problem it's so weighty yeah it's so weight it's 100 metal right yeah it's steel this is 174 ph stainless steel so also this dragon won't rust yeah no and there's value in heavy people you know they say they put makeup containers they put fake metal in them because people value heavier objects and more so heavy can be okay but on that note this is actually a perfect segue let's talk about not heavy so you know obviously the ability to lightweight you know uh desktop metal acquired this company idro yes in italy specialize in valves and hydraulics components mostly with dmos with dms but they have incredible knowledge of design for additive and generative as well as assembly consolidation and lightweighting as you're seeing what's been so cool about working with hydro is they looked through all their projects that they did with dmos that ended because the park cost was too high and they couldn't meet the volumes and a four number of those are now being converted over to binder jetting because the cost is lower the volume is much higher like we can do a couple hundred of these on a shop system in a bill so now you said uh that doesn't weigh as much now is so this is a 60 reduction in weight and how do they do that just simply by changing geometry oh this is this this is this this is the oh oh okay yep so simply just by changing the geometry this is a great example of a really nice size part for binder jet as well as just the ability to post machine uh to retrieve criticals you know to be able to just have to touch up a couple dimensions really quickly on maybe a two and a half axis you can you could produce a whole bunch of these real quick on that shop and that's what they're doing especially with the supply chain where it is today yeah we're seeing a ton of interest in in bringing manufacturing back on shore with binder jet i would imagine that is an essential technology to to help alleviate supply chain issues on this side yep and i think that what i do is doing with design for additive is incredibly important uh educating people on how to take full advantage of the process is so important especially as we're moving to higher volumes where it's not just that i'm printing one of these i'm printing hundreds or thousands tens of thousands i want to make sure i'm optimizing my part for the process and for the application so that requires then a skilled workforce or at least a well-trained one i think that's something you walk around here you see the softwares that are coming out and it's something that's happening it's getting more accessible it's getting easier uh to really make sure you're taking full advantage of the process i would imagine this because the shop system has been around for a few years yeah i think i saw it a couple of years ago next germany when we launched that machine yeah and i i would imagine it's gone through some uh maturation right it's definitely a lot of process material development uh really just it's become a really bulletproof system it's really exciting this is a really good showcase of the the savings that this sort of technology can offer especially because these perform the same function but this weighs less costly less absolutely looks cooler and i can rant about binder jetting all day i'm sure it sounds like what i love about binder jetting is when we're talking with customers or people in the booth it's not even so much that we're competing with you know all of our friends here at the show we're competing with traditional yeah i'm trying to convince you to buy a printer instead of investing in a tool or going to asia to cast where it's actually economically in the right applications for the right parts it makes sense to actually print these parts which is what's so exciting about what's happening in the industry is that we're competing more with traditional now than we are with each other and the whole industry is kind of moving towards let's let's take traditional into additive instead of just you know right bickering between each other anytime we talk about taking uh taking on traditional here on in the u.s there's there was always that caveat of having to spend more but to make it here in the u.s yeah and so what you're proving now is that isn't necessarily always the case because the technologies additive technologies advance and now we can do manufacturing in the u.s absolutely without having to pay that that that fee to do absolutely essentially which is that is really exciting that's really cool that's a real that's really right so that's really exciting so continuing to talk about binder jetting well you do you do love it i love binder jetting sorry one one thing that's really been happening with binder jetting is material advancement okay uh like pick this up and i want to see your reaction well this doesn't weigh anything it's aluminum aluminum has always been incredibly challenged for minor jetting because of sintering challenges right isn't it liquid phase entering potentially it's it's uh it's hard to center so yeah phase change wait meaning meaning it pulls up yeah yeah yeah it oxidizes and creates a low and that oxidizes meaning oxygen it it turns into aluminum oxide there we go yeah and it surrounds the molecules that actually shouldn't get too material sciencey here you can say something that i anyways it creates a lot of difficulties in centering because you end up melting the part on the outside while you're centering the part on the inside well essentially from the polymer world it would be like printing pla at 300 c you know there's no conformity to it sure yeah yeah so obviously those challenges are beginning to become overcome same with copper which has always been challenging yeah look at these though these it's not just overcome i mean this look good yeah yeah the parts look incredible crisp details of course there's still time to you know we gotta make it bulletproof before it's released but yeah it's really really exciting because you know aluminum we get asked for a lot so it's really exciting to be able to put that in someone's hand especially when you compare it to a steel part and they're like oh my goodness well yeah but if the aluminum material can withstand the the needs of the part yeah and you can make it this is 6061 so it's it's a it's a high value aluminum but you're gonna make a lot of these yeah that looks cool this is a eat-in pump component so it's a straight-up copper straight up pure copper and i'm sure you can think of you know that's just a lot of sample but you can imagine the applications that i'll have for heat exchangers right that's just it anytime you can maximize the surface area you can maximize the surface area that's just it you your design for additive now takes into account maximizing the surface area for dissipation especially with battery applications we're seeing more and more of really you see a lot of this yeah why is that just because the heat you want to dissipate the heat to ensure your battery can be as efficient as possible that makes sense yep so continuing one continuing one more take all your time joel oh it's all right one more binder jet application but with our forest our wood your binder jetting wood upcycled sawdust held together with a binder going to give a shout out to our customer here rp speakers who designed this beautiful speaker for us here that it is allowing us to show it there is something about introducing the organics to the digital yeah so this is sawdust held together with an organic binder like like salt like sawdust like i just swept it up the floor sawdust yep what oh okay yep uh sawdust swept it up off the floor put it into this prints on the shop system as well jenning an organic binder onto that to hold that together afterwards you brush it and it actually just soaks up that binder all the strengths coming from that binder epoxy material but you get that wood aesthetic and this has been so interesting because you go to a furniture maker who i didn't realize that sawdust is a huge issue you created from a number of people yeah it can be relatively dangerous to handle you don't want to be inhaling it it can be flammable and you have to dispose of this so you tell them that they can have a printer that they can turn that sawdust that's a waste into more parts and they are static so and i i mean imagine having to pay to dispose of something that you can now instead utilize and make money from like absolutely absolutely and obviously right now we're seeing a lot of these art projects really organic shapes all that grain here is just printed in as a dye oh really industrial inkjet print technology is what we're using right so it has multiple channels so we can just add those dies to the process if anything that was a harder software challenge to prompt to solve how do we map those screen structures to the three-dimensional shape then cut it into 2d slices but the ability to print those dyes and you can do really really cool patterns organic super cool all sorts of different uh stains and grains but you can now customize the look of the wood that you want to use so you can see i mean these are meant to be you know the grain of the wood yeah but you could you could technically customize the grain to be a logo it could be a logo that could be like a light at that point that's cool yeah it's it's really really incredible uh one thing that's really exciting about this too is we're actually seeing a lot of applications for parts that would have been made in plastic but wood has traditionally not been something that you can easily mass produce no no no it's always been uh a craft thing right it's been handy so the ability to print you know like we talked about something of this size and wood and i can print a hundred of them in a couple of hours we're seeing actually a lot of applications that they would have used plastic but now they're switching to wood it's more sustainable they like the appeal better and they actually are happy they're not having of course to invest in a tool to mold or something like that which is really really exciting that you know today a lot of the applications we're seeing are art and you know lamps and things like this in the future we're going to see even some industrial applications where it's just made more sense to make it in wood than it would in the plastic well what you're going to find is a lot of people who now have tons and tons of sawdust absolutely with all these parts that can be made from it it's like well there's no reason that has to be plastic and we already have and the material is essential is almost free you know it's it's really really really cool they pay people to take it now so absolutely it's even more than free and like once something is that low cost you start to find a ton of applications i don't know if you've been over and seen all the stuff we're doing with sand on the x1 side of things no but sand is also incredibly inexpensive to print like just same sands for casting applications mostly but also tooling applications right because it's rigid it's structural and it's really inexpensive to print so these big thermoforming tools wash out tooling uh sand with a binding agent and yes and then they can infiltrate it they can polish it whatever you come come by i'll show it to you later uh just because when you drop the cost of the raw materials you start to find a ton of applications which is really exciting sounds like it yeah this is empty well this has been a lot of fun oh my gosh i mean dragon was cool obviously the weight savings here and being able to print the copper the wood stuff is neat i i don't know why well and the ring was cool and we had the foam the foam is gone the phone was cool but for some reason my brain just took to this because it is a it is a solid part but it has a just that enough of enough give to the surface it makes it so dramatically different than what a lot of people think about resins and it's right look at this and i don't think rez and it's like justin like yeah plus you get all the other benefits of dlp of course but it's it's just incredible i love this part thank you so much thank you for having us and thank you everything yeah i appreciate it this was fun i'll i will come by the booth please do it yeah i want to see the sand stuff all right let me pack up all my goodies you did bring a lot of goodies and they were awesome absolutely i challenged everybody i said it's show and tell show cool stuff tell me about it i you answered the call all right thank you i get to keep it plus your heart all right see you soon i got a ring oh hand me my uh ipad there okay this has been an insane journey through the cool stuff in additive manufacturing i am so thankful to be here and to be able to show you this uh i i mean you know at the end of the day it's my job uh and i and i love being able to do this i love that this is my job but um it's it's a joy to do it's i i feel like uh i'm not just showing you really cool stuff but i'm inspiring some to take this on or maybe to to go on a different path or one time someone wrote me a 12 year old wrote me a piece of fan mail and in that piece of fan mail they said it's because of you and your content that i want to be an engineer and it's just you know it's just it just makes you tear up a little bit because it's like oh you've helped borne an engineer into this world world needs more engineers check for your needs wear the ring okay i just don't want it to if i swell up and it's on my finger for good then i got to cut it off who's also a huge fan of it digital what is the digital manufacturing challenge winner digital manufacturing challenge winner okay this is our last guest his name is ben ben all right and ben is a digital manufacturing challenge winner is that right yes it is hey ben pleasure to meet you good to meet you now hang on give him a background hey ben what do you do so we were the winners of the digital manufacturing challenge it's a student competition for solving supply chain issues through additive manufacturing oh it seems like a a pretty cool sort of competition yeah it's it's really it was really a great opportunity for us and you won yes we did and is this a showcase of what you use to win yes this is so this part is um let me let me give you some background okay yeah yeah let's do it so we're a boeing sponsor team they came to us with a fleet sustainment problem they've got a lot of planes a lot of older planes that need replacement parts like one off replacement parts that can't be manufactured using traditional means or at least would take a lot of time and money for a one part i see what you're saying okay yeah for example this part was uh an aileron cam it goes in the wing and it helps the wing flap up and down i see oh and looking out the plane window when i see the wing they've got the those are the ailerons there that helps direct the wind okay so i'm following the original part which was on a 50 year old plane it was cast magnesium which is yeah so magnesium is really light and it was casted so that you can get the weird shape okay geometry um the problem with that is magnesium is really dangerous to manufacture and it's got a flash point right right it'll it'll it ignites it ignites okay and the precision casting molds that they need to make would cost boeing half a million dollars for a single part so boeing was looking towards this manufacturing method um to produce parts that are a lot cheaper and a lot faster so the type of technology we specifically used was hum it's hybrid wire arc additive manufacturing okay so i understand wire arc out of a m that's it's a wire feed with an electrical arc to transfer right but hybrid yes hybrid hybrid okay what does that mean so hybrid is both additive and subtractive what it is our hybrid machine is like a three axis cnc mill but it also incorporates the you know added part the mig welder at the front okay as a tool offset so what happens is when you're depositing a shape like this you deposit a layer of material but to deposit the next layer it needs a you need a consistent flat surface so it goes and switches to the cnc mill mills that surface flat like what you see here and that allows for a really really consistent layer height and really consistent deposition yeah that that sounds like well that is a great way to do things and i would imagine you need to be able to produce a part especially for aerospace that can withstand certain stresses right they want they want to uh what isotropic part right in order to to qualify because it's you have to qualify the parts for the aerospace industry yep and so by doing that you create an isotropic part right not necessarily okay so part of the project um we need to our project was more about having a process deliverable as opposed to a product so we were in charge of saying hey using hwam can is it feasible to create a part like this or other replacement parts and have it work for like spare tire applications like you need a plane just get from wherever it is right now to an actual fulfillment system uh facility i say an actual replacement part okay so can i touch it yes i was about ready to just like fling it around what happens is we needed to do all the material characterization to make sure that we can take this model run it through topology optimization and through topology optimization we can lightweight it since this is aluminum the original part was magnesium oh so you still get lightweight benefits of aluminum yes so once so that those material characteristic steps we printed like thin walls that we cut dog bones out of in both uh vertically printed and i guess horizontally printed and we use astm standard e8 uh tensile testing to get our material properties okay we did find that the material was anisotropic where it took less force to pull it apart vertically so what we did was we created a custom material profile to go through the topology optimization so this entire part is simulated and designed around isotropic properties but those isotropic properties are the minimum viable strengths that we can get out of this oh you can put in the isotropic properties of the material yes and then it'll it will design the part in a way to take advantage of those properties is that right kind of fusion am i close yes okay so the minimum so the way topology optimization works is we're given a part and we're given a load case okay so for example you've got a main pivot here this is an entire bearing surface and then there's two other main pivots okay well and just to be clear so uh in fusion 360 i've done a little bit of topology optimization because i made um frames to hold filament on the wall and so i had a flat surface and i had you know a point where two things attach and i said what is the minimum to make in order to make it look good um okay but you just took it to the extreme because now you're taking the material properties and adding it to this process yeah so i see what we have to do is we have to create that custom material profile and then once we have the mesh that the topology optimization generates for us we can't just print the mesh the problem is this specific technology like for example you can't use support material because you can't remove that after the fact i guess oh right it's not easily removed yeah that makes sense and you also can't bridge because you can't weld on nothing you're depositing liquid metal on that's right but there's nowhere to support then yeah you can okay that makes sense and there's also the you know normal you can only print out like a 40 degree overhang stuff like that yeah that makes sense i understand that part okay so we generate the mesh using our custom material profile and our load case and we use that mesh to inform a final topology optimized design which is pretty much taking this part and redesigning it using the uh the mesh as kind of an influence so then if i'm hearing you right then that mesh helps influence the topology optimization in that it knows the load or the load or the abilities of the material and so it can pad certain directions okay that's really cool that's really cool so like these these thin features here this is where the stress actually travels when you apply a force down here and you have your bearing surface here this is where the stress travels through which means hey we don't need all of this material on the inside so we can just not print here so this is printed as a hollow cavity that we don't have to do the post processing steps to hollow out later right so weight savings time savings exactly all that cost savings but the problem is we do have to print these walls solid because we can't print bridges we can't print overhangs like that i understand okay that makes sense so after we get it from the deposition model which is like the kind of the raw structure you can see here right i can see that yeah yeah yeah so we take it from the deposition model then we do a lot of fixturing on the same machine since it's a cnc mill anyway we position this sideways and we do all our other operations to get like precision mating surfaces like oh ice precision holes and especially this big this big pressure load here i see so and this has not been machined yet right wait this has here this has not this has not yet okay i figured but this has i can see the actual tool so this is possible specifically for weight saving since we're going from magnesium which is a lot lighter than aluminum to aluminum we have to get the part as close as possible to the weight of the original part which was still taking advantage of the material properties exactly in the correct shape thanks to the topology apology that gets a little complex it was it was a very long project and we had a lot of different phases you know we had to do material characterization we had to do topology optimization but on top of that there's no set software tools like off-the-shelf software tools that allow you to go from like a like a model to hybrid like there's stuff for additive you can add stuff yeah you subtract stuff but there's not a lot of them between like putting those together so we have to come up with our own like we have a we have a github with python scripts that we use to oh man put those two together so that we can eventually get to a part how difficult was that process so i've done very little python oh we have a question from the audience so they want to know about the we because a student you just graduated from virginia tech yes do we know who this we is is it just you or there are more people yeah we actually have five other guys standing off to the side here um we were we were a team of six people six of you yeah okay so this was our um like capstone project our final mechanical engineering design project i see yeah before you graduate yep i see so this is this was a two semester thing so we did all of this work in eight months and it was a it was a lot of work it's a lot it sounds like a lot of work let's go back to i want to go back to the python because you created essentially the the missing software you needed to complete this operation so the python it wasn't so i was i'm the one who pitched and did the initial prototyping of the software that we used um pretty much what we needed to do is we needed to add decking passes between each layer like i said you would deposit a layer and then you needed to add the deposition so what we did was we used python to read the script as it's coming through if it sees a line that doesn't work with the machine because we're using we're using this prototype uh hybrid machine that that doesn't have off-the-shelf software so if it included a piece of g-code a line of g-code that it physically couldn't process we needed to get rid of that automatically i see yeah i see so the python was massaging the script to make it work with your hybrid machine it also added in those decking layers so we could say hey from this layer onwards add this line of script between each layer i see thank you uh that's really cool so part of what makes it really special too is that when you're doing it layer by layer you're ensuring the part has the proper characteristics at the very end like you're not you're not having to go through and and and do it at the end and there might be pockets that you can't get like doing it layer by layer and especially with the decking process is going to ensure your final part is exactly what you need yeah the main the main advantage i'd say of this kind of technology is that the quote-unquote buy-to-fly ratio is really low to fly yes buy-to-fly ratio is how much material you start with in terms of your billet size for like solid like a solid chunk of aluminum right so how much material you have to start versus how much you're getting rid of and how much ends up in your final part okay well being this is that if you're you're saving a ton of material exactly so you go like a ton of material 74.6 so we go from a butterfly ratio of 10 for a part like this to 2.56 which is huge because we're only adding material exactly where we need to and then just and just essentially a little finishing pass exactly each layer which isn't taking off that much but enough to ensure the part is exactly what you need yep and then additional the final fixturing where you put the parts sideways and [Music] you do all your you do all your pockets right that makes sense wow so you said this was with boeing correct yes this was uh sponsored by boeing sponsored by boeing uh what were their thoughts on it they really appreciated it i mean like i said before if they were supposed to do this like in their labs it would take half a million dollars to create the tooling and the molding to come up with the same part right right we were able to take the part cost down since we're using off-the-shelf welding wire and argon gas we could take those parts parts cost down to less than 500 that's that's insane anytime you can talk about cost savings and still giving them a part that they want they're going to jump at that and i mean yep i do that's awesome ideally what boeing wants to do with this technology is have fulfillment centers located all across the world so if you have a you if you have a plane that's grounded you go to the nearest site that has one of these machines you print the print the part get it on the plane and you're good well i would imagine too if fulfillment centers like this we could actually not even have to bring the part to the center if certain parts could be made and sent the closest center to the plane yeah that's down could actually send the part and whether it's 100 or 200 miles away it's still a massive savings in cost and time and effort yeah well i want to thank you for coming on the show because this is incredible thank you so congratulations to you and the team man thank you this was a pleasure this was a lot of fun you know what if people hear about this that camera right there the front camera right there if they want to know more about this tell them how they can find out that's a great question well if you're interested in being part of the organization that helped us go through this definitely go to the dreams lab website so the dreams lab is the additive manufacturing research lab at virginia tech and they'll probably have an article about what we're doing here there we go well thanks again hey man thank you enjoy the rest of the show you too don't hurt yourself with that that's really heavy yeah you want to can you [Music] freaking killed it yeah we did it and just like that show-and-telling so now we have to have seven people right yes where'd it go i got to get my gotta get my chat there we go i will take that from you patrick prince nine p.m here i'm almost eyes closed i understand ah that this was a lot of fun um i'm i'm i'm really thankful i was able to bring you along with me on this journey for three hours at rapid tct 2022 we had an amazing time we had an amazing backdrop hey there's food yes if you made it this far you are awesome be prepared for some amazing content from rapid tct 2022 i look forward to bringing it to you print all the things and as always high five
