360 LIVE: 3D Printing Tips with Fusion 360

hello everyone and welcome to another episode of our fusion 360 tech Tuesday my name is Brad talus from Autodesk and today's topic we're going to talk about some tips on 3d printing from fusion and this is actually a real-world example my son is in high school and they're teaching fusion 360 at his school and they were tasked with designing a couple gears as you can see here you know and you rotate them and they mesh together etc and they basically sit on these posts so he wanted to 3d print them and take them in and show how they worked and so he sent them to the printer but when he went to assemble them so here's here's the base and here's the gear right he went to assemble them and it doesn't fit so he wasn't able to show how they worked and he was like well why is that and so that's what we're gonna talk about in today's livestream is creating 3d printed parts you have to take into consideration some tolerances and I'm just gonna show a couple tips on what I usually do on creating some of the stuff that I print and you can see from the back here I like 3d printing we're going to talk about printing you know large objects like the stormtrooper helmet etc so let's dive right in so one of the things I'm going to talk about is dealing with the tolerances in fact you can actually see this one is now fixed and you can see that slight gap between the post and the gear and this is what's allowing that to rotate and every 3d printer is different some might have tighter tolerances than others and so what I do is I create what I would call almost like gauge blocks for testing out shafts and holes so you can see here I just created a really basic part and if we were to inspect this surface here we can see that that's a half inch diameter post and then I print this and I say okay that's supposed to be a half inch and let me go ahead and show you here so here's here's that part you can kind of see it here I'll take my tool let me switch two inches really quick and I just measure across that and I can't see what it looks like it's exactly half an inch so this makes me happy my printer is pretty darn perfect for printing that post now you'll notice over here I have a bunch of rings basically and I've thrown some text on there and what I do is basically create a gauge block of different sizes okay and when we print that it ends up looking something like this and so what this allows me to do is I can now come in here and I know the very first one is half an inch so I can see that that actually does not fit there's there's no tolerance there whatsoever and hopefully I don't know how well this is going to share but then what I could do is I've gone up you know about five thousands on each of these so I can see that one still doesn't fit that one starts to fit but doesn't go down the post very well so that's still too tight and I can just keep working along until so here for example that one slides on fairly easily and then this one here again slides on fairly easily so that's the point five two and the point five two five so if we switch back here it was this one right here this point five two and there's point five two five okay so then what I do is I know that that's fairly close oops to drag so then I created another one where I went up you know point five to five point five to six point five to seven and printed that out to just you know basically tie in that tolerance even more to figure out what is the best one now you don't have to do this you know it depends on how much slop you want or how tight you want that to fit but this basically allows me to kind of dial in and figure out which is the the best one so let me switch back here so this is the second one that I printed this is the first one you know where I went from point five one two point five two five I'll do the exact same thing here so I'll I'll kind of test fit you know and it allows me to just basically get where I feel the best fit is I don't know if you can hear you know the scraping or whatever going on but actually right about here is the one that I really liked the best of the last one just a little bit too loose for me so the point five to nine is the one that I really like and I'm now I'm basically I know that if I have a point five inch post I want to make the hole or whatever that fits over that to be point five to nine okay so I'm gonna show you how I did this infusion so basically what I did I'm gonna show how I created these and then I'm gonna show you how do you add this you know point five to nine to your designs so a couple little tips and tricks here I'm gonna switch in this case I'm gonna switch into inch since that's what I've been talking about so far I'll create a sketch and actually the very first tip I should show you in regards to 3d printing is right up here you'll notice that my Z Direction is pointing up okay if I go into my preferences you'll see default modeling orientation and sometimes it could be y up or it could be Z up and if you're doing a lot of 3d printing or kam for example I would definitely recommend switching that to Z because a lot of the the slicers out there say that Z is in the up and down direction so we want to kind of match that if it was Y up my when I go to 3d print my parts will be 90 degrees from the bad which isn't a big deal but it's just one more step that you need to deal with so the very first thing I want to do is make sure that my Z is up okay then I'm going to come in and create a sketch and let's just draw it on this kind of this top plane and I'm just going to create a circle and in this case let's just do maybe let's just do one inch okay then I'm going to create another circle inside of that and we know that we want to start at about 0.5 so I'm going to say 0.5 so I just created two circles which basically you know creates this kind of this washer shape now I'm gonna pattern this I'm gonna do a rectangular pattern just draw a box around everything and start to drag now I could leave the spacing like this but then it's gonna print out a whole bunch of individual blocks engage blocks if you want to call them that which you know is I think harder to manage and deal with or whatever so I actually overlap them just a little bit something like this for example and let's do maybe four in one direction and I'll come down and do I'm going to do the same thing I'm going to overlap them a little bit like so and let's just do two in this direction now because it's a pattern all of these are the exact same size so I can't come in and change this it's basically creating a copy of this original and patterning it however if i zoom up you can see this kind of this little square icon I just clicked on right there that's actually the pattern constraint and if I double click on it it actually allows me to come in and edit my pattern so if you ever need to come back and change your pattern you just click on that icon but what I'm going to do instead I'm gonna select it and then say delete so we used the pattern to kind of create or shape but now they're no longer linked so for example I could come in and throw a dimension on this guy and say you know point 505 and it's gonna be kind of hard to see but you'll see that these circles are changing now so then I can say you know point 5 1 and you see that got a little bit bigger and so all I have to do is just you know quickly come in here and say point 5 1 5 and continue going through this ok so this is how I created the my gauge blocks so the tip here to take away is the fact that you can use the pattern to kind of create your shape and then delete that pattern constraint and then come in and tweak with this so let's just say point five three and then finally point five three five or something and again you can make these dimensions whatever you want so I'm going you know in a fairly large step first of all - you know so for example let's go ahead and create a circle another circle over here and let's make that point five three five so we're actually taking a look at hole diameters between these two lines so hopefully my printer is is you know good enough to be able to print pretty high quality between these two and so I'm able to then really kind of narrow down the exact size that I want for clearance so I'll stop my sketch and then you just basically have to select your profiles now you're noticing I'm gonna have to come in here and select a whole bunch of these little faces and a lot kind of stuff which would take quite some time so instead let's just do a press pull I'll draw a box around the whole thing and then I can come in and clear out the big regions the the circles so I think that's much faster than trying to have to select all of these little tiny ellipses that you see so another tip just you know kind of simplify your process there now if I wanted to I could you know take these sections out if I want to which is kind of how I did it in mine and then I'm gonna go a specific distance let's go in this case point one two five now why would I want to do that well we're using this as a gauge block to see what size circles they are but I can also use it to check my thicknesses so if I say print point one two five I could then measure that with my micrometer here I could say okay let's measure that distance and see what the what the distance is of course my counter turned off and in this case it's point one which is probably when I made it in my original print instead of point one two five I probably just did point one but that way I can verify what I'm sorry about the reflection what thickness this is okay so another way to kind of help use this one tool in multiple different ways now it what I did was I actually created some text and also I'm gonna do one of those but I'm gonna click on this face right mouse click create a sketch okay then I'll go into my text command kind of put the text where I want it to be and let's just say 0.5 0 now you'll notice I can do a vertical flip a horizontal flip I can change the size let's just make that point 1 2 5 that's a little small so let's try point two that looks a little bit better and maybe I'll make it bold okay and then I'll position that where I want I just grab that little round ball with the crosshairs and I can kind of move that where I want that text to be I could come in and change the font if I want to I'm just going to go ahead and say okay now this is still text now I could copy this so I'm going to control C control V so just like you would copy text or a photograph or something like that I did a control C and then I did a control V for paste and I'm able to drag that across okay so now let's pretend I did all of my text what I need to do is to select it right mouse click and say explode text I get this question quite often it's like okay I can create the text but I can't do anything with it as soon as I say explode text you'll notice that it turns it into a profile okay so I'll do the same thing over here I'm going to edit this text first of all let's say 505 maybe drag that a little bit to the left maybe look at it from the top again I move that in place where I want it and then I could come in here and say explode text and now that's its own little profile then I could come in and extrude this so I'll go ahead and select my profiles now you'll notice that this is taking some time and think about how many circles I have and if I'm doing two or three of these gauge blocks or whatever this could take some time to do so now I'm going to extrude this up and let's just say point zero five or something like that I'll say okay and you can see that it actually extruded that text as part of our gauge block now like I mentioned that could take some time so another trick that I do so I'm going to undo back another trick that I do is I create a reference so instead of using text I might come in here and just put a notch let's just do something like on this guy here and I'll extrude that through the part so I'm just gonna click on that face there and I just create a notch like this now now I'm not having to do any text but I can go ahead and turn on my sketch and here's another tip for you if you right mouse click on your sketch and say show dimension I'm gonna go ahead and click on show dimension and I'm still in 3d I'm not in my sketch environment or anything like that I'm actually able to see my dimensions in 3d so now you can kind of see what that looks like and when I print this I could just come back and look at my screen and say okay I know that this is the point five one and this is the one that I liked okay that's point five three so instead of taking all that time to you know create the tacks and extrude it and type it in etc etc I'm just gonna use this kind of as a reference so another time-saver I looked over at the chat window really quick and I saw somebody asked why do you have to explode the text and that's a real good question basically you to turn it into a profile so let me show you again I'm gonna click on this guy we'll just say create a sketch and I'll do my text so I really appreciate these questions I know Aaron's helping me out here answering some of these questions for me so I'm gonna rotate that around make it bold change the size I think we said point to was good okay right now it's just regular text if I say okay I can edit this text so you'll notice I can say edit I can you know add stuff to it so text to for example I could change the size the angle etc but if I say stop sketch you'll notice I can't really do anything with it I can edit it but I can't extrude or anything so if I try clicking on this you'll notice I don't get the option for example to extrude okay however if I click on it and say explode text you'll notice it's now it looks like a profile it's no longer blue on the inside and there's actual profiles here the drawback with this is if I right mouse click there's no edit text right we basically said take that text and turn it into a profile so you want to make sure that you've got your text the way you want it to look before you explode it okay so it's a great question there okay let me undo back to here so I saw somebody said you can click on the text and say press pull and you'll notice that does work okay so I think it was Chris that said that's so yes very good point you can use the press pull command which is basically offsetting faces or extruding faces or doing a fill it depending on you've selected so yes you can do the press poll great job good observation there okay so again it depends on what you want to do you can do a reference like so or you could add the text if you want to so okay yeah thanks for pointing that out Chris I appreciate that okay so what I did here is I've created my my gauge blocks basically and I'm ready to print I want to test print this actually the other thing I should probably do is create my piece that this is gonna fit on top of so let's just do the exact same thing I'll start with a circle let's make this an inch and a half in diameter just for fun and then I'll do point five so let's just say point five I'll stop my sketch I have my sketches turned off so I'll turn those back on I'll say extrude and again I might go a very specific distance let's say point 1 to 5 in this case okay then I'm gonna turn that sketch back on and I want to select this other profile and I've shown this tip before but it's kind of buried it's actually underneath that's right here but instead of having to rotate I can actually just click and hold and it allows it to kind of probe through the part and you can see it's gonna first find the face then the profile and then the bottom face so I can go ahead and select the profile and extrude this up now again I could be very specific this is coming from the bottom so maybe I want to see how accurate my printer is so I might say I want my post to be one inch tall but because it's going through my part it wants to cut so we're gonna change that from cut to join and it's actually going to join those parts together and then finally I'll come in here and typically put a small chamfer on the edge so let's just say like 0.02 or something like that maybe even a little bit larger 0.04 let's do that and say okay that way it kind of helps guide the gauge blocks on to the post so okay so now I'm ready to print so there's a couple options here again I'm using the new user interface and I don't know if you saw the video that was just released about the update there's a lot of really cool enhancements and one of them is talking about the new user interface so I'm gonna come over here into tools and here is my 3d print make icon so under the make pulldown we can do 3d print you can get a quote from proto labs you can do you know 100k garages etc but we're going to say 3d print now you'll notice it says selection and so if I pick on this guy it's only gonna select this particular part if I try and add in this one over here you'll notice it unselect that and it's only gonna print this particular part okay so by saying 3d print it pretty much limits you to one body now I'm gonna show you a really cool workaround to get past that okay so let's go ahead and pick on this one here first and I'm going to talk about this 3d print menu so I'm going to zoom up a little bit here so the first thing it says preview matched if I don't have that turned on you don't really see anything but I like to have that turned on and I can kind of see the the accuracy if you want to call it that of this 3d print it's basically the refinement so you'll notice here it says there's gonna be about 850 triangles to make up this curved body right now it's set to medium if we change it to high you can see went from 850 to 1720 and a lot more triangles okay so again depending on what you're trying to print and how accurate you want that to be you might want to increase your refinement I can say low and you'll notice you know 400 or you can say custom and what that allows you to do is to actually come in and kind of tweak with your surface deviation your normal deviation and this minimum edge length I use quite often and you'll notice it's set fairly high and if I look at it kind of from the top it's kind of hard to see cuz of all the triangles but basically there's a look really large triangles going back and forth to create these curved surfaces but if I bring this edge distance down you're going to notice the parts gonna start to change what it looks like so I'm gonna kinda keep cranking this down a little bit so instead of big long triangles it's now kind of broken down almost into like quads like these little squares of triangles and you can get nicer looking results too again depending on what you're trying to print by changing some of this deviation now 99% of the time I just use these but if I was doing something with really complex surfaces I might want to come in and specify my surface deviations and my minimum edge lengths and even my you can change your aspect ratio of how strong those are so you can kind of see how basically more more edges are being created for this vertical post here so that is your refinement options okay and then we have this output and you have the option to send it to a 3d print utility okay now you'll notice mind says cura and that's because I actually have cura installed on my machine by default you'll probably see like meshmixer Print Studio and preformed and custom but let's say you're using simply 3d or you know cura or slicer or whatever some of the other ones are out there if you don't see that in here all you have to do is click on custom and then you'll notice this little folder icon and that's gonna allow you to go out and point to where your slicer is at so for example mine is in Program Files under ultima Corcyra and all i have to do is point to the cura application and then that will show up in my pulldown list so that's how you add in your own slicer into this list so I'm gonna say cura and I'm gonna say ok now what this is going to do is it's gonna start up cura on my machine unfortunately it takes a little while to look up Kirra but it's gonna only bring in this particular part but we'll notice a couple key things here it you know shows me what that's gonna look like I have all my settings it has my printer in here etc but the important thing is notice the orientation of it and again this is because we did the z-direction pointing up ok if I didn't have that pointing up it would be rotated and what I mean by that is it would come in bring it back Kirra hopefully oops may I move this over so you can kind of see it my part might come in looking something like in fact I've seen it before where it's basically at 90 degrees to the table so it would it would come in looking something like this ok if I didn't have that z-direction up now you know that's ok all I have to do is come in and say you know rotate and rotate that 90 degrees but I don't want to have to do that every single time so again make sure you say Z up okay my next tip here is what if I wanted to print all of this at the same time and when I clicked on this make it only let me pick on one of these at a time even though I'm holding down control or whatever okay or shift it doesn't matter it's not letting me print both so to get around that all you have to do is the right mouse click at your top level in your browser and say save as STL so I'm going to go ahead and click on this and notice this time it's giving my preview for all of the parts and this looks pretty similar there's some slight changes but the key thing is notice it still is gonna allow me to send to my 3d print utility to cura okay so I find myself actually saving as STL more often than clicking on the 3d print icon because I typically kind of position the parts the way I want in fusion and then all say print okay the only difference you'll notice now is you'll see this format binary or ASCII and then you'll see the structure one file or one file per body so if I were to say one file per body it's only going to output you know basically two files here okay I'm gonna leave it one file I'll leave my refinement medium in this case and if I do not have this turned on and I say okay it's gonna allow me to save this locally onto my machine as an STL file I could email this to somebody I could put it on a flash drive whatever you know stake it out to my machine or whatever okay or I'll do that again save as STL this time I want to send it to a 3d print utility Kyra I'll say okay it's gonna bring up my slicer whichever one that you have selected hopefully I'm looking at some of the chat window I can see people are saying oh that's great about the Z up and I hated it when my prints were rotated 90 degrees so hopefully you're learning how to resolve those but notice what happened this time in Curacao you'll see it actually brought in all of my parts and I'm ready to slice okay so I'll go ahead and slice this really quick it's I clicked it twice as as unable but now it goes there it goes so it's gonna take two hours with the settings that I have I'm actually printing something else right now with really high info so that's why it would take so long I wouldn't have that much in fill layer view we can kind of slice through and the thing I love about designing parts in Fusion is they are always watertight unless I do something majorly wrong you know it's I design something in fusion I send it to my printer boom it's done it's that easy so okay so with that hopefully that the main tip there was to create some gauge blocks to try out the tolerances on your machine okay so we determined basically point zero to nine is the difference between this shaft and that hole so how would I do that in my designs so what I would recommend doing let me switch back to solid here is I would create a parameter okay so I'm going to say change parameters and we're gonna create a user parameter and I could just I could call it whatever I wanted let's just call it tall for tolerance or something like that and what's the expression I'm gonna say point zero to nine I'll say okay I now have a user parameter called tall so as I'm creating my my new part here let's just go ahead and design a block or something like that and I put a hole in here that I want to have I'm gonna say that's point five plus whatever my tolerance is so I just start typing in like tol and it's going to become point five to nine okay let me edit that again what did it do it took I wanted the hole to be 0.5 so I don't have to remember okay everything is 0.5 now needs to be 0.5 to 9 blah blah blah all I have to remember is I want that to be a half-inch hole then I'm just adding in that tolerance and the reason I like doing this is because maybe I do a test print and it's not quite enough well I could come in here and say for example let's go into my parameter so I'm gonna just do a I did the S key hopefully you guys know this shortcut s brings up your shortcuts and you can search so I'm just gonna search for parameters and I'm actually showing this from a because of a live stream earlier on when I was talking about parameters somebody said oh you can't edit your parameters when you're in the sketch mode and that's sort of correct yeah it's there's no menu that says change parameters but I'm able to find it through my my sketch search and I can come in here and say ok my parameter let me move my screen so you can see this so let's say instead of point 0 to 9 it's now point 0 5 watch what happens to my circle you saw how that got larger okay so I can come in here and change this all day long and it's gonna update all of my holes ok so that's how I go about doing this so let's do something else let's say 0.125 plus taul okay so now that's gonna be 0.15 for let me move this out so you can kind of see that better so again all I care about is that's a point one two five whole but then it's going to figure out what it needs to do to make the tolerance correct so okay hopefully that makes sense and if I were to print that the the post would fit down inside of that part okay I'm glancing over at the chat window making sure everybody is hearing me okay it sounds like people are learning Lots I love the S key that's really cool the next tip I'm gonna show you is a little bit different and this has to do with Oh actually before I do that let me back up a little bit I started out by showing these these gears right that didn't quite fit so all we did is we loaded up my son's 3d model he already he spent a lot of time designing this gear here and stuff like that you can kind of see what it looks like and we just went in and edited the sketch for the hole and and added that point zero to nine and now we can actually put these together I'm gonna try to assemble this is all at the same time live on camera right it's a pretty tight fit let me do the small one first but it actually does mesh together and and we can see how smooth and there's no like there's no slop or whatever in here it's a really nice fit in fact if anything it's a little bit of grinding going on but now we're able to show how these gears interact with each other so solve the problem using a little bit of tolerance the next tip I want to talk about is assembling lar parts together where for example my printer isn't the biggest printer out there it's only got about a hundred and twenty square millimeter bed and height so I can't print really large objects but on something like this for example this helmet here it's actually broken down into a lot of smaller pieces so it's kind of hard to see but these are a lot of smaller pieces and there's a trick with lining those parts up so for example I've got these two two blocks and I want to glue them together or line them up and I don't know if you can see here I've got these little pieces of filament sticking out of the block here and on this side there's little tiny holes okay and all I have to do is basically line those up and snap it together and you'll see how that's perfectly lined up I could glue this together and even help strengthen the thing if I were to glue this so I'll show you how I went about creating these little pins like this and all that is is extra filament so all I do is stick a little piece of filament in there and trim off just to leave a little bit of a post like so you can see right there everybody has filament laying around so what I did was create a basically a block of filament so I'm going to expand this open let me go into here and I'm just gonna load this guy up so you'll see I just called it filament and this is the exact diameter I need for my filament to fit in a hole so let me go ahead and tell you what I mean by that I'm gonna measure this guy and we can see that the diameter is point zero seven okay but if I were to actually measure my filament let me turn this guy on real quick it's point zero six nine when I measure it so I you know figured out what size hole I need to create in my parts for the filament to fit in nice and easily okay we're not going to force it in there so then I'm gonna use this little piece of filament so for example if I were to let's just create I'll keep it simple here let's just do a box and I'm gonna make this you know two inches by two inches let's just say by 0.75 let's just let's just do something like that okay what this is going to allow me to do is I can then come in and use this body so let's just go ahead and move it into place here I'm just gonna kind of get it where I want okay and I want to make sure it sticks out so this is half of an inch in length so I'm going to come in here and let's just move this guy I'm gonna start to drag and this is kind of a cool trick here you'll notice that it's referencing right there okay I can click this little down arrow and say re-anchor and what this is gonna do is you'll notice it's saying that it's moved from this back face 1.30 8 inches so it's it's measuring from that back face but let's say I want to measure from this front face so I'm going to say reinker and click on that front face and now you can see it's saying it's about 0.5 inches from face so if I start to drag backwards I can go minus 0.25 okay and we can see it sure enough it's basically halfway buried into the part so that reinker command is really really cool let me show you another example I'm gonna come in here and just say press pull as I start to drag it's saying I've pulled it about 0.4 1/8 inches from where it was well maybe I don't want to specify the total length not the little distance here so I'm going to say reinker grab that back face and now it's telling me the whole length and I want the whole length to be 2 point 1 2 3 4 5 or something like that and that's what it's going to do from this back face so I use that reinker command a lot so pretty cool command okay so now I'm gonna just basically you know copy this guy and paste it so let's just drag that over a little bit and honestly I could be very specific with the dimensions if I want to but in this case it really doesn't matter I'm just going to you know oops let me if I have to say create a copy so let me do that I'm gonna say move say create copy and then I'm gonna start to drag and it'll allow me to do that and I typically do three post kind of to register from you could get away with two if you wanted to then we'll come in and let me just go ahead and mirror this block so I'm going to say mirror this body here on that mirror plane I'll say okay so let's just call this block one and call this guy block - yeah - okay that way I kind of know which is which right so I'll turn that guy off so we can kind of see what's going on but then I just say come in here and combine so the target is gonna be that guy and the tool is gonna be these three pins basically okay now I'm gonna keep the tool because I want to use it again on the other side so I'm gonna say keep tools I'll say okay but if I turn these off you can see that it subtracted those out there these holes are exactly a quarter of an inch deep and then when I go to you know print this it it's the little holes in there for me again hopefully you can see that and I just stick the filament in I don't really care I don't measure to make sure they're exactly half an inch or whatever I just stick you know the filament in there I lost my my large piece of filament disappeared somewheres can't show that anymore by sticking in there and I just trim it off with a pair of snips or whatever and then that allows me to line these up okay so pull that guy off so we get something looks like this I usually put them all on the same side and then we can line them up and print I mean I really like about this is like you know I created this rectangle in the top to make sure you know those really do line up and it helps with strength so that's another tip that I use for creating some of the larger prints so hopefully you learned some tips and tricks on creating prints with a fusion 360 with creating those gauge blocks you know I showed so these guys I showed the the post I use this all the time and even when I like switch filaments sometimes some filament changes now I I use hatch box I really like it a lot I'm not affiliated with them in any way but if I were to switch to like amazonbasics or something like that I would probably do this again just to make sure that they print pretty pretty similar before I start you know wasting a lot of material and going to assemble them together and realizing that they don't work so with that I hopefully hope that you learned a lot we just released a new version please make sure you check out what's new I'm gonna be showing some of it what's new here in upcoming live streams the fact that we can now Bend sheet metal parts along an edge like along a sketch line I am absolutely ecstatic about and we did a lot more enhancements besides that but you can tell I've been waiting for that one for a while I'll be showing that I'm also going to be doing another cutting board I did one a while back on you know basically creating some blocks and kind of copying and pasting and somebody put in the comment about how you can use the pattern command where I was like oh you can't pattern because then you can't slice through the part I learned something and I can't wait to share that with all of you it saves a huge amount of time so I'm going to be showing how to fix that cutting board that I created earlier and I'm going to show you how to create another really cool cutting board so you'll see that in an upcoming livestream so with that I hope you have a wonderful rest of your day make sure you subscribe leave comments topics you want to see and I'll see what I can do to help all of you out so see you on a future livestream thank you you
