SUPER FAST 3D Printing at RAPID + TCT!

rapid tct 2022 is here and we're kicking things off at the mosaic booth you've seen a ray you've seen element and we're going to show you something really soon called stitch that's just going to blow your mind there's a lot of really cool stuff here to see as well and we're going to take you on that journey follow me [Music] it's not often at rapid that you're asked to shake a machine is that right logan that's right so pantheon design we've we've talked before an email sometimes it fell through we finally met up here at rapid and they are just north of me in british columbia yeah we're just above you in vancouver this though this is your amazing machine so what's what strikes me is the speed at which this thing is printing yes how is this possible at accuracy so the whole design philosophy was speed and reliability and to achieve that we put servo motors on we put ball screws on we did away with all the belts everything is machined there's no plastic parts taking any force on the machine and that's how we're able to achieve print speeds at 400 millimeters per second and travels at one meter per second one meter one meter per second meter per second for travel and 1g acceleration so we're almost always at top speed geez okay i'm looking inside and everything looks to be super custom yep hot and custom hot end custom hot end joint developed with slice engineering okay and we've got a force gauge in there so we do nozzle touch right off the bed meaning you can stick phenomenal you can change the whole printhead out and you just calibrate again and you're good to go it's moving so fast yes yes it's quite quick now like i said at the beginning though you said to shake the machine is that right yes shake the machine just don't pull it off the stand that it's on and we'll do it well as as long as we're rolling we shall have that it will probably still print to be honest right we'll have to immemorial rest in peace okay so give her yeah give her i mean give her a good shake like shaking is is it heavy it's not too bad yeah yeah as long as you're on the there we go i'm on the table yeah aced it didn't even skip a beat no not even not even like not even a hint of it no we have actually put a ups in the bottom of this stuffed it in a truck while printing and gone to a customer's place i printed while driving yes and i could tell that there were imperfections in the print from some of the more non-perfect roads in seattle that i went over absolutely we get away with no imperfections there because we're running a floating frame everything's mounted to this top plate so the bed holds plain with the printhead not the ground so the whole thing floats and that's how we get away with the vibration and maintain good wall that's cool yes sir wow and it's just the servos driving x and y how is z uh z is stepper motors and then servos x y and we've got our own board connecting to the servos from a duet 3d board so i would i would love to put this machine through its paces maybe borrow one for a little bit uh since you're so close to me maybe i drive up we we we uh we have a beer and then i bring one home for a bit oh perfect we could work that out we've got any good beer in vancouver i love hearing that and it'll print on the way home yeah yeah exactly we i don't know if we can send you home with enough battery power to get uh get all the way back but we'll try well now it's up to you everybody viewing this it looks like i'm gonna have a pantheon machine for a bit in the near future and i'd love to know what you want to see printed and how you want me to print it if you want me to print it shaking or upside down or on its side or while driving everything's up for grabs at this point logan thank you man thank you so much great to finally meet you know this it's a fidget cube and to print it via fdm you have to have incredible clearances and command of tolerances to make it so you can fidget with it once it's done but my friend cuba here is going to show us the qls 820 from nexa and how they printed 500 or more of these in 10 hours yes exactly we printed 10 hours 10 hours yeah it's unheard of for this volume and this amount of parts out of sls technology and uh what we did with this this build we packed the job with 65 packing density which is unheard of for sls technology of course this is not functional part it's just a fidget but it shows that is it possible now now 65 you mean the total build volume of the 820 yes 65 of that build volume was consumed by things that needed to be printed by parts yes and in sls terms the reason that that's unheard of is because typically when you have that laser sintering you can't have it sintering so close to other parts right yes uh there is a heat accumulation record of the core of the bill and uh this heat can leak to the other parts uh we try to control this process very diligently that we don't have this bleeding and overgrown into the parts and uh yeah that's why we were able to achieve that well now i want to hear more about the machine because we see this pack this cake of parts here and if i come over here you've got more parts you've got plenty of parts that were printed on this machine so what what makes you able to do then that sort of job how how come i can do 500 more of these 65 density in like 10 to 12 hours what makes that possible yeah it's a couple of components which uh which stack together first of all we we decouple the printing process from the cooling process because with sls for typically for every hour of printing you cool for about hour and a half and we decouple this process by designing this machine in two pieces so the top piece is a printer with four high power lasers working simultaneously right here they're delivered over here yeah and uh this is where we get the speed so four lasers working together give us speed yeah and once the print is done we can immediately take the build unit out imagine it's a cartridge for your 2d printer you run out of ink and you just swap new cartridge and you're good to go and this is exactly what it is and that's why it's got a handle because this just takes out and you wheel it off yes and the printer itself with the four lasers then is ready to receive another cartridge per se and you could just go right you can just go yeah we believe in concept what's called lights out factory and this is a very first step to do this it means like you can print 24 hours seven days a week uh without operator on site without the lights on a well yeah and the way that we do this is uh by putting this whole printing platform on agv which stands for autonomous gated vehicle okay yes this thing has motorized wheels and it can do uh it can change the build unit by itself so you don't have to have operator on second and third shift you can just schedule the build job and once the first build job is done and the building it goes out by itself from the machine and the next one in line go inside and start the production by itself see that's really cool because when if you imagine automated factory floors like if you think of an amazon warehouse they have all these robots exactly just going everywhere exactly so now you can borrow that concept because the printer is detached from the build platform and the cooling oh that's really cool so there it is so then of course with the lights out no one's home and the build that it just finishes a print and this just drives off to some area to cool properly yes and in the meantime you still get access to the printer because a new one comes in exactly wow that's really cool in the future we plan to have station where it will charge itself with new powder and go back again to the to the oh so the lights out factory we're talk this doesn't just go to a place and cool off where an operator has to then depowder and sandblast and stuff we're talking about the automation of that as well yes yes we have to we have to automate the whole workflow from beginning to the end of the stream of the workflow well the automation is great anytime you think of a future factory automation is key and that's kind of where we're heading it's really cool to hear about this because i could just imagine a camera off in some corner just catching robots essentially dancing and when they're done with their dance you have usable parts d-powdered blasted and ready to go exactly and in you can run those machines from your uh from your couch there is no uh human interface or like a panel on this thing uh we run those machines from our tablets and our phones because it's a web browser applications you can connect through the vpn to your production floor you can monitor it on fly you can see your statistics we have software which monitor key performance indicators like success rate uh errors if there any and you can schedule the jobs and you don't have to be on site this is this is future happening right now industrial additive in pajamas you call it yeah i'll borrow that yeah there you go the revo is great it allows you to change your nozzles easily and you've seen it before i really like it but these are new and allow extended functionality can you talk about it yeah so uh this is the obsidian version of the revo so the um brass nozzle is now a two part assembly so the outside is a copper which allows us to get lots of heat into the material and stuff like that and then the tip is a tool seal so we're just putting the abrasion resistance right where we need it and then over the top of all of that we've got a diamond like coating um which is basically nano diamonds so diamonds famously pretty hard so that adds even more is tiny nano is tiny which is good as well i think um so yeah that adds yet more abrasion resistance on top of the tool seal and then the the coating is also really non-stick as well so particularly in fill materials where you have all the fibers which can kind of like clump up and make little burgers that go into print having that non-stick property is really invaluable as well that's really interesting i like the property of non-stick because i don't like boogers when i'm printing either and it's really interesting that you actually have that insert so you have tool steel where it matters but you're keeping copper on the outside for its heat properties yeah so um i guess compared to a brass nozzle typically with uh conventional harness steel nozzles you'll have to like bump the temperatures five degrees something like that just a little bit but by having the clock around the outside now you can use the same print profile for both the obsidian and the brass nozzle so if you were printing with pla one day you wouldn't necessarily have to change out the nozzle just to treat the profiles to kind of compensate for the different material right oh that's really interesting yeah i've printed with hard nozzles before and a bump of five or 10c on the nozzle is usually something that i have to do in order to to print properly with it right just because of the the properties of the tool steel but because you have that two part you've got hardened steel insert you don't have to do that yeah just makes it's a small thing but it makes it bit friendly for the user right well that's what this is about friendly yeah uh friendly use cases right being able to hand tighten hand remove and now you don't even have to change out the nozzle or change your property the properties of your slicer profile in order to print properly it's a lot of keywords exactly with the obsidian being an insert and we talked about how it has the um the tool steel in the middle and the copper on the outside i just got word now that that is being applied in a different way and we're talking about a higher flow rate system so so the v6 e3d v6 with typical materials like a pla what sort of flow rate will that see yeah so your flow rate does depend on things like temperature and material you're using uh but a v6 is around the 20 mil cube a second kind of mark but now with with this new thing that i'm hearing about you're utilizing the inserts to create a high flow system yeah so we've taken the stuff we're doing with obsidian so insert based nozzles and we're making these crazy inserts that have like projections and cross holes and things like that all to increase surface area and mixing um which allows us to drastically increase the volumetric throughput but keep the same overall nozzle length so one day you'd be printing with a 0.4 and then change it out one of these high flow nozzles and it will be the same length but we'll be getting you know flow rates again depending on material all that stuff around the 35 mil cubed a second and that's what we've got so far it's not quite finished cooking so we reckon we can get a little bit more out of it than that but 35 mil cube per second is is a incredible speed yeah and you're saying that's not it like this is just so far but if the the cake's not done cooking basically yeah so 35 milligram is significantly more than a volcano for it for all the other things being you know other variables being the same and yeah we've only been having that in development for the last i don't know six months or so so yeah a few more months i think we can get that significantly higher still so in a few months e3d is going to announce this and people will get to learn all about it right yeah that's incredible hey rory thanks man nice phone the smallest mosquito ever well smallest mosquito so far so far so far so far i mean the little bugs that fly inside the blind they're a little smaller and more annoying what am i holding come on yeah it's so tiny it is tiny so this is called the mosquito conduct it's our latest version of the mosquito conduct conduct yes because it conducts heat away from the hot end as opposed to using convection where you would need a fan so no fan on this hot end okay it's designed to be mounted in a heated chamber in an industrial application and it mounts to a metal plate that has enough surface area to pull all the heat away uh i see so it sinks away that heat and and it doesn't necessarily need to have a fan even on that it just needs to have enough surface area to sort of balance the equation once it reaches thermodynamic equilibrium which is kind of fun you don't have to get all the heat away just enough just about that spot where it likes it exactly the goldilocks zone precisely so what application would this serve like what problem does this solve so what we invented this because we were working with a customer that was printing peak a lot but then they also had custom their customers were needing to switch from peak and other high temperature materials to lower temperature materials like pla and petg the normal stuff and what happens if you're trying to do that is if when you pull the hot end down to go then switch to a different material the peak or other pi tent material crystallizes inside of the hot end and then if you want to switch to like a pla you have to heat it up to the point where it starts melting and what it can happen is it can clog up the heat break if you're trying to put pla in it so that's no good not good at all so you get this massive massive clog very expensive material really sucks i would imagine this helps enable more functionality within people that are doing high temp and low temp you know materials doing you know high temp one day low temp the other day because i would imagine plugging issues are a a bane to these people's huge bane especially when you're using something like peak right very expensive so that reminds me of a story uh we are working with this gentleman named eric lamarre who 3d prints prosthetics in guatemala which is pretty cool yeah so he's helping people out for free and he contacted us because he has a raised 3d machine that he was having to watch all day because it's really hot in guatemala and so they were experiencing heat creep issues so how did you solve that so we solved that with a fun copperhead upgrade for the race 3d that we sent to him and uh he's now able to print 50 faster and doesn't have to watch his machine all night long so eric in guatemala eric guatemala he's a pirate lives on a boat eric the pirate in guatemala yeah he's a good fighter he's printing on a boat yeah prosthetics yeah to help people for free yeah wow it's pretty awesome that's actually really hot that's really incredible yeah that's awesome he does not have an eye patch and no parrot either but maybe a monkey someday maybe yeah i mean we can hope we can hope hey man thanks for letting me come by and see this i'm at the impossible objects booth and that means i'm here with my own personal god of thunder thor hey thanks for having me what's going on man oh we're live we're doing it live we're doing it live that's right so we recently did an episode where i featured some connectors printed with impossible objects technology that held the full joule but one of the connectors or two of the connectors i'm trying to remember when they were printed it was a different model so this piece right here wasn't as thick right correct yeah proper model carbon fiber peak going to be super strong it's going to hold them well in the episode there were comments where people said it was only half the joel because i i had the the uh the strap connected to two pieces and so right it splits the weight load and so now what i need to do is connect both of them up to this and step in yes well actually i might make it uh i'll i'll put it on my truck on the tow hitch and maybe we chose something we'll see what happens the new truck but this is awesome so i will i will pack this all up nice and safe i'll take it home and perhaps in the future the near future we'll do a part two excellent that should be fun okay so so i got this thank you thor oh you really appreciate it but what's the news what's the news you want to share the the cvam2 we're we're adding newest coolest stuff so we've uh been doing a lot of upgrades on the stacking so increasing your productivity and stacking meaning the amount of stuff in in a in a squish yes so stacking the sheets but also stacking for the squish yes oh okay okay so uh basically quick recap um we're using sheet lamination process where um we're impregnating uh impregnating these carbon fiber sheets with peak or nylon 12. that's right yes and then it's it's impregnated and then you have the pressure add heat at molten temperatures correct and then you get something like this end up with this we do a little bit of archaeology using a sandblaster and we remove all of the unbound fibers from that that carbon fiber block i remember at the time i asked how precise it was and yes i mean i've got super tiny little mini jewels that were made using that process so we know that detail can be achieved yes absolutely um in other news in other news other new stuff we are working on a camera system that's exciting it's so exciting it makes it so much better for our operators it's getting to the point where you know we can just do our normal startup procedures and then be a lot more hands-off um it's it's it's an ai based um uh camera system that's gonna be identifying issues before um the operator even has to which is awesome it's so much nicer for us oh so this is directly impacting your job yes immediately better yes it is so much better now it's awesome that and combined with the the new stacker it's been incredible plus there's been little tweaks and improvements all over the machine um to you know make it more efficient it's going to be um it's just all around better it's it's it's getting better here yes so do the cameras produce an image that you can save like are we going to see images from that camera pop up online showing us cool stuff soon very soon yeah so um uh not today not on this machine but in chicago we do already have a system in place to do exactly that which is so cool because i can sit at my desk and i can see what's happening on the printex that's so it's so cool i'm at the luma field booth and i'm here with my friend eduardo and why am i holding a rubik's cube you're holding a rubik's cube because we're about to look inside of it now normally to look inside of a rubik's cube i put a screwdriver in there and i take it apart destroy in a violent process that is a little bit kind but you could do this in a different way that's right yeah so at lumafield we build a non-destructive testing system called an industrial ct scanner it allows us to look inside of any object without taking it apart cutting it in half any of those sorts of problems well when some things about a ct scanner they think of hospitals medical facilities and looking inside the human body exactly but you're using a ct scanner to look inside manufactured objects that's right yeah well we were talking earlier and someone mentioned that this runs on household power so i could just plug this in that's right next to the coffee maker you could put this in a conference room or a hallway or a garage or wherever you feel like scanning things you said first design principles is that right what does that mean yeah first principles thinking is where you look at a problem and then you think about what am i allowed to do based on the laws of physics and you build up from there so instead of saying what are the components we have to buy off the shelf from vendors that have been making things for 30 years what could we do if we wanted to do this as cheaply as possible as excessively as possible as easily as possible without being constrained by the way an industry might work traditionally oh i see so when okay typical ct if we're talking about that they have the constraint of the human body and the conditions that we can that's right as humans yeah withstand but when we're talking about objects obviously the the design goes around the constraints there and because you i believe someone mentioned it's higher powered is that right it's higher power than a traditional medical scanner but it's not any higher power than a traditional industrial ct scanner they've been industrial ct scanners for a long time that makes sense they've just been really expensive so we wanted to bring the cost down substantially and make it much more accessible in the same way that you know 3d printing in say 2002 was really so expensive that very few engineers had ever used it now we're here 20 years later and it's something that so many people have access to we want to do the same thing with ct scanning that other companies have done with 3d printing that's really cool it seems like ct scanning would be great because looking inside of something that's manufactured really gives you a better idea of yeah like how it can withstand certain stresses or how an object might be made better with certain parts added or removed i mean you've seen all sorts of cases yeah you can see interesting things like porosity you can see electronics we have these fun little flip cards yeah i remember these yeah you can kind of tilt them back and forth and here we can see all the insides of the speaker so you can see if the electronics are soldered correctly or if there's any potting in the wrong spot or the wires are in the wrong area inside of cast or injection molded parts you can see if there's any voids or bubbles that form during solidification with 3d printed parts maybe you care about having a lightweight lattice inside of a part for an aerospace application how do you know if the middle member of that lattice is solid or not you'd have to cut the part in half traditionally but with our technology you can just look at it and it's a break apart the rubik's cube that's right exactly it's really interesting though that you're talking about the price coming down because it means that because we've seen a lot of people who are able to do small batch manufacturing and so this sort of technology what you've done in reducing the price allows people who have maybe smaller factories or small run shops to be able to have that that quality control and the ability to look into what they make and to offer a better product yeah well you know what i have this thing in my hand i'd love to see let's look inside can we do this yeah it's super easy so just set the object here this is a bunch of foam i was going to say this is foam yeah this is just foam that's film that's our magic secret uh if you put your rubik's cube in the foam the reason we use foam yeah just set it right there do i have to mix it up at all no you're good uh you could if you want to but uh i don't know if we'll be able to solve it with a scam but we'll see what we can do the foam is used because it doesn't absorb as many x-rays as the solid object so whenever we're viewing it the phone basically fades away and then you just see the object so it becomes very clear and that makes it easier to do all the complex math that's needed to reconstruct the object in three dimensions but we'll just look at the 2dx right so come on over here okay so this is the machine here what's it called yeah so this is the neptune ct scanner that's a fun name we like it a lot yeah and i've got a rubik's cube on your magic foam you've got it in the phone so all you have to do is set it on that turntable right there okay here we go yeah great so the next step is to close the door that's it though that's it okay you're ready to rock whoo it's not hard not that hard at all so we latch it in place and then we get a signal right here it says x-rays are ready everything's safe key is on key is on okay we're in a good position we just hit this button our x-rays are turning on they're going to stabilize what does that mean it means the x-rays have to warm up so if you think about like an old-fashioned light bulb yeah an x-ray source is really just a light bulb there's uh it is an old technology yeah there's a coil that's heating up and then it's shooting electrons out and those are striking a surface and that surface emits x-rays so now whenever you turn on an x-ray source it has to heat up and uh you know once we have our preview that's updating here and in just a second we'll be able to see the rubik's cube so we just gotta wait a second there so x-rays are coming in there we go that's the inside of the rubik's cube you can see the those are so these are fasteners that's right those are the screws that are going into these springs and those hold the uh the things in position that's what allows you to feel the kind of detents when you're moving we just have to hit this one button here it's going to optimize all of the settings for the scanner it's going to run through a few different exposure settings gain settings x-ray power settings all the different things that make up a really high quality data set it'll optimize for this and then it's going to just start scanning it normally that process on an industrial machine that could take you hours and it might require someone who has multiple years of specialized training to be able to go in and get the best possible scan so we're scanning i just set up all the parameters and it's ready to go so the way this is set up right now there's some bars that we can move around this is estimated to end at 11 o'clock so it'll be you know 45 minutes 45 minutes gives you time to get a coffee right exactly when people want to know more where should they go to find out yeah just go to lumafield.com or you can google lumafield we're the first results and from there it's possible to go in you can examine a scan library we have dozens of objects that we've scanned you can create a free account and explore scans yourself you can look at like on the inside of things like uh airpods uh you can look at like toys pez dispensers natural objects all kinds of crazy stuff we have in there it's all pretty cool man that's really cool well thanks for thanks for letting us take a take a little look inside of something yeah thanks for coming by yeah appreciate it and we're back at the mosaic booth as you've seen we showed off the array i'm here with my friend the element and it's really exciting to be back here because lots of cool stuff to show you plus lots of cool stuff at this show right what was your favorite part let me know down in the comments below if you've made it this far you're awesome don't forget to hug each other more see the next rapid and as always high five
