1. 1 Intro: 2. 2 Units and Grid Settings: let's take a minute to tweak a few settings so that we're both working on the same page. The first thing we'll do is make sure our units is set to millimeters. So if you look on the browser, you'll see units. And if you have her over this little pencil on paper, I can't will pop up, go ahead and click on it and go under unit type and you'll see this little drop down there of click on it and you can choose the units you want to work with. We're gonna select millimeters, So go ahead and click on it and click. OK, I'm already set to millimeters. So I'm just gonna click, cancel and you can always check just to make sure that it's the right units just by looking at it. So it says mm, so we're good. Next, we're gonna go ahead and change our grid and snap setting. So click on this little grid icon here and we're gonna go to grid settings. You'll get this dialog box and will make sure that fixed radio button is selected and go ahead and answer 10 for the major grid spacings and minor subdivisions. We're gonna set that toe one and then go ahead and click. OK, What that did is if I go into sketch creates sketch and I'm gonna choose this red green plane. If I zoom in, I can see that I have these these grids. So if I choose l four line and I started drawn alive, so each ah grid is gonna be 10 millimeters, so you can see I'm 10 20 30. And the reason I wanted you to do that is because when I start sketching, I'm probably gonna zoom in to a certain area where you know, it's gonna make sense for the scale that were drawing with that way. If if you see me draw something that's about you know, 2.5 grid spaces, you want to do something similar as opposed to being zoomed out, let's say this far out and drawing something here, we're now you're at about 80 where you should be about 25. Um, it will just make things flow a lot smoother if we're sort of working within the same scale . Okay, so I'm gonna go to stop sketch the next thing we're going to change. Um, and this is just preference. But here we'll go back again and to, uh, into our sketch. And then just to show you if I zoom in, um, I'm doing that by rolling the scroll wheel forward and a membrane and backwards are zooming out by scrolling backwards. But you can change that. Yours might be opposite, um, and this is just sort of what feels right to you. Um, but the way to change it is to go under. You'll have your name here. Whatever the name you gave the account, when you set it up and you can go down to preference and you'll have this little, um, part here that will say reverse zoom direction. So this should just be under general. He can choose different options here, but under general, you'll see reverses, um, direction. So if it's zooming in or out words, um, you know something that you're in a way, that's not what you're used to. You can just click on this to reverse it. Um, so this is the way I like it. So I'm going to keep it the reverse so that scrolling forward goes in and scrolling backwards zooms out. Okay, those were just the three things I didn't just wanted to, um you know, make sure that, um you have all set before we begin our model. 3. 3 Sketch Our Profile: Okay, now we're ready to begin working on our 1st 3 D principal design, which will be our handy tweezers. So open up Fusion 3 60 And as you can see, you'll start with a blank screen here, which will just have the title Untitled. And so we'll have to give it a name and save it. So we'll go ahead and click on the little Save icon and let's go ahead and call this tweezers So we'll go ahead and create a new project to put all our models and you can see here. It says, safe to a project in the cloud will click on a little drop down arrow because I don't want to save it to the current project it said to, and we're going to create a new project here by clicking the add Project bun. I'm gonna call this tutorial designs. You can give it any name you want, Um, so we'll just go ahead and click on save, and it's a good idea to begin saving or start your designs by saving them, because that way, effusion will then automatically start auto saving, and you don't have to worry about losing your designs so you can No, no, Here. That on the top it went from entitled to. Now it says tweezers, view one. So let's begin. We're gonna go ahead and click on sketch creates catch. Infusion 3 60 will prompt is to choose a plane. Where are in the three D modeling environment. So we always have to first choose the plane we want to work on. I'm going to choose the X Y plane, or you can see here. That's going to be the green red plane. I'm going to start modeling by creating a rectangle. So I'm gonna go to Rectangle. In this case, I'm gonna true sense of rectangle. I'm gonna click on the origin, click and release the mouse bond and move my mouth out. And I'm ready to enter the dimensions that I want this to be 15 millimeters in height. So I'm gonna hit 15 enter tab and then hits 80 or enter 80 for the with. Now I can anted enter twice and there's my rectangle. Next, I want to go ahead and sketch arc. On this end, I'm gonna choose the three point arc so we'll go to sketch arc and three point arc and I'm going to zoom in Now, get in the habit of zooming in. I always notice my students who begin modeling and they will sometimes be all the way. Zoom thou and they're trying to draw. And it just makes it very difficult to make sure you have really chosen, you know, the right point you're trying to draw on and, uh, leads to errors. So I always try to fill your screen if you can or ah, to the sketch that you're trying to draw. So in this case, I have selected the three point arc in the three point arc. Works by, uh, basically asking first to select the first point. So I'm gonna select this corner, and then it wants the second point, and the third point is going to be the bulge. So you can see I can just move my mouth's to select the bulge. Now, as I start bringing this out and increasing that bold, you're gonna notice that it's gonna snap into place and it'll snap once it reaches a perfect hemisphere. Yeah, I can continue to grow bigger and you can see you start to bulge even bigger. So let's go ahead and just start going until we get it to snap right into place and click. Okay, so now I'm gonna go ahead and get rid of this line here because I want this to be all one sort of continuous profile. Um, And notice if I can select of this and this independent from each other. So to trim this line, I'm gonna go to sketch trim. Noticed that there's a letter next to it which says, t. That's the keyboard shortcut for that particular option. Eso Any time an option has, ah, letter next to it. That's the keyboard charcoal. So we'll be slowly getting used to using these instead of actually choosing it from the menu. So I now would just select trim, and I can highlight Ah, the line I want to trim just by hovering over it. So let's go ahead and click on this line, and that line is gone. So if I hit escape now, when I select this, see how the whole thing will now select as one profile 4. 4 Sketching Continued: Okay. Next, we're gonna use the offset tools I'm gonna go to sketch. I'm gonna go down to offset most e o Choose Offset, and I'm gonna click. I can click on any one of these lines, and the whole thing will highlight. So let's click on it. And I get this red border around the entire profile. Not could drag this outwards or inwards, um, and notice if I go outwards, it turns into a negative number. And if I go in words now, it's positive. So I know I want an offside of two millimeters, so I'm just gonna hit two and enter. Okay, The next thing I want to do is I really want this lying to come all the way across and meet this line here. Now to do that, I can go ahead and choose line and just draw a line across. But there's actually an easier way I can go to sketch and shoes. Extent. Now, the way extend works is if I just hover over the line. I'm trying to extend. It will actually show me in red the preview of what that's going to look like. So that's exactly what I want something to click on that you know, I got my life to extend to the other life. So let's do the same thing with this line here. I'm going to click on it, and I got my extension. All right, I'm gonna hit t for trim and get rid of some unwanted lines. So I don't want this line here, and I don't want this line here now that left us with a pretty much top down view profile. What? I want the tweezer toe look like So that's looking good. Just a couple more things I want to do before we extrude this. And that's going to include putting a little tapered angle on the top and bottom here of the I guess what would be sort of that? The clamping fingers. Because when they come together and wanted to be able to meet each other in A in a way, that's going to be flat, and I'll show you what I mean. So we're going to start with I'm gonna hit our press l for line, and I'm going to draw a line from anywhere here on the top to the bottom, like notice. I get this little right angle constraint here showing me that that line is going to be perpendicular to the horizontal lines. I'm gonna click that and notices it stays there showing me that that's the perfectly vertical line. So that's what I want. So I'm gonna hit or go to sketch, go to sketch Dimension. I noticed a d I'm going to select it and I'm going to click on this line and this line here , and I'm gonna enter a sketch dimension of five millimeters and hit. Enter. Now I want to draw a line from this corner at an angle to here, so I'm gonna head out for line. I'm start right on this corner. Notice it turns into a little box once I get that corner. And I wanted to be sort of on the bottom half notice. If I go right to fire over on the midpoint, I get that triangle showing me. This is the mid point. So if I was looking to split this in half, it's easy to find that midpoint by just getting it to reference that triangle. So I'm not sure exactly where I want to be, but I know I want to be in the lower half of that. So I'm just gonna click anywhere down here and now I can actually enter a dimension for this angle. So I'm gonna hit the first sketch dimension and hit this line or click on this line and this angled life. And now, instead of, ah, the mention, I get the angle that pops up So it looks like I drew it at 5.7 degrees. So I'm going to click on it. And I want that to be exactly five degree. So I'm gonna hit five and enter. Okay. Now, while I have to do is hit trim to remove some of the unwanted line. So I'm gonna hit t for trim and remove this line this line and I'm also gonna move this reference line that I made here. Now, that looks good. I'm gonna do the same thing on this bottom part, so we'll start off with Al for line and I'm gonna draw a line. And this time I'm gonna purposely dry, um, cricket, just to show you guys how to easily fix that. So let's say you drew that line, and it's you meant for it to be vertical um you don't have to undo in re dry. This is a great, um, way to start using constraints. And so if you look here at your sketch pallet under constraints, there's a whole bunch of constraints that you can use, and I'll be introducing them more and more as we go through the models. So the 1st 1 we're going to use is actually the vertical or the horizontal slash vertical constraint. So I want this line to be perfectly vertical. So I'm just gonna click on this constraint and click on this lie and notice that it made it perfectly vertical. And it gives me the little icon there showing me that that constraint, um, you know hasn't been applied. The way that works is it actually will apply the closest constraint that that lie, um, is angled toward. So if it's that line was closer to being vertical, it's gonna make it vertical. If it was closer to being horizontal, it would make it horizontal. Okay, Now let's hit D for dimension, and we will again dimension this line to this line to be five millimeters and will now go ahead. Had l for lying to enter another line in this time, we're gonna go between this point and somewhere here, right on that line was women a little bit and had d again. And this time we're gonna answer the angle to mention. So we're hit this line in this line between that angle that we want click again and enter Dimension of Five. Okay. And I'm gonna t for trim and going to click on this this line in this line to trim those out and also click on this and this lying to remove those Can I consume out and that looks to be exactly what I want. So I'm done with this sketch for announce. I'm gonna go ahead and click on Stop sketch. 5. 5 Extrude: Now I have a profile that will be able to be extruded up. So what I'm going to do is go ahead and click on, create extrude, noticed the eat, and I'm going to click on this profile. It's gonna turn blue. I'm gonna orbit so I can start Conceive this arrow. I'm going to start dragging this up and notice I get this dialog box and there's a few options here right now. I'm just gonna go ahead and make sure that this box is 10. That's the same option as setting the distance over here. Um, the other options are the direction operation and extents. We're not going to change any of these, so just leave it as as and we're just going to click, OK? All right. So now I have an extrusion. Ah, and I have a three d shape now, and that's the approach we're gonna take throughout every model, um, that we're gonna design in this course. Basically, we're going to start with a sketch, and then we will extrude that sketch to be a three D shape. Okay, A few more things I want to do to this tweezer. Um, it'll actually you know, if I printed the way it is right now, it'll print sign. But let's let's just make it look a little bit nicer. So I'm gonna hit on the Q b here, um, to get it to a line. So I'm looking straight at the side, and what I want to do is I don't want this to be a complete, just sort of a perfect rectangle. I want this to have a little curve. Um, that's gonna go hit from this end to the bottom here. So to do that, I'm in a sketch on this side profile, so I'm gonna go to sketch, create sketch and instead of selecting one of the planes, So notice here, have these light bulbs next to my body so I can actually expand these and also the sketch. If I uncheck the bodies, lightbulb, the body will get out of the way. And I can see I have access to my three planes, so I'm gonna turn the body back on, and I'm actually gonna choose this surface of my model two sketches, that of one of the planes. So let's click on that. And now I have this plane selected and my body is still shown there. So I'm saying the playing on top of the body. But I can if I get rid of that. You know, I'm still sort of left with this outline of the plane. Now, what I want to do is reference these corners because I want to draw from here to here, so actually want a reference thes sides. Um, the way to do that is by using the project option which will project the model into my current plane. So notice if I'd get rid of my body. If I turn off this light bulb here, you know everything's going, um but if I turned on the body and then go to sketch, go down to project include and go to project, I can go ahead and now click on the lines that I want to project. So I'm gonna project this line, this line, this line and this life, and I'm gonna hit okay, over here on this dialog box, Okay? Now I can get rid of the body and I have these purple lying showing me the outline of that particular model. So the way I want to do this, I want to create a narc back. It's gonna go from here to here. And I wanted to stop about three millimeters up from this corner. So first thing I'm going to do is I'm gonna put in a point, so I'm gonna go to sketch and we'll choose point. And I'm just gonna set that somewhere here in this lower half and in it D for dimension. And click on these two points. This and this. Bring that out and interests catch dimension of three millimeters. Okay, now I'm gonna go ahead and select my three point arc, so I'm gonna go to sketch are three point arc again and start at this point, come out to this point and I can set that bulge. So in this case, I'm just going to give it a little bit of a bulge and notice again. I get that snapping feature that looks like a good place to Teoh set the bullets, so I'm just gonna click again, and there it is. So that's that's all I needed to today. So I'm gonna go ahead and click Stop sketch again and we'll turn the body back on. So now I want to be able to extrude this top part out to cut, um, to cut this top section and just leave you with this bottom part. So to do that, I'm gonna go to create extrude, and I'm going to select this stop profile and I get my arrow again. I can neither push this out to create some more jam a tree, or I can push it into the model to cut and notice over here how it goes from join when it's being pushed out to cut when it's going through the model. So I'm just gonna for this instance, I'm gonna go past what I need to cut and just head. Okay? Notice that the pink area is passed my cutting profile here, So I'm gonna click, OK? And that left me with this curved shape that I was looking for 6. 6 Fillets: Okay, now I want to extrude these out so these will be sort of the guy gripping pause. I guess you can call him. Um, so I want him to be extruded out a little bit, Something Hiti for extrude. When you click on this, start dragging it out. Actually, I only wanted to be one millimeters and, uh, and the extrusion length, so I'm gonna collect one and just head. Okay, I'm gonna do the same thing with this side. Now, if you want to, um, reference your last feature infusion, all you have to do is right. Click on the mouse and whatever you did previous exercise, it will have a repeat of that function. So in this case, it was extrude was the option that I used last. So if I right click, I get the option to repeat extrude. So I'm just going to click on that. You click on this side as well. Give it a extrusion of one millimetre and click. OK, that's starting to look good. Now I want o enter some fillets in here, so I'm gonna go ahead and go to modify fill it, and I'm going to start with a fill it right here on this corner and someone to click to select that. And I'm gonna do the same thing with this side. Notice that it's smart enough to know what I want to select. So if I I don't even have to hover to go around the other side, I can just sort of click over here or, you know, I believe it's you know where that option is and it gives me that lie. So I'm gonna go ahead and click on that to select both of these. And I'm just gonna start dragging this out. And I think two millimeters looks good for Philips. I'm gonna click, OK, And one more fill it will be between, um, this edge in that age. So gonna hit f for fill it, click here, click on this edge and I'm going to sort of do the same thing. Just kind of start dragging it until it kind of looks right in this case. Ah, fill it of about 10 millimeters. Looks good. So I'm going to click. Ok, All right. And that's our tweezer. That looks really good. So now this is ready to be three d printed. So there you go. Enjoy 7. 7 3D Print it: Now that we've finished making our 1st 3 D principal design, let's look at how we would send us to the three D printer. So with fusion 3 60 this is actually very simple. Long gone are the days where you have to install a separate plug in to export this as an STL and then open up your printing utility to bring it in. Um, all you have to do is take a look at this I can over here, which is three d print so or where it says make. Go ahead and click on it and you get this three D prints dialog box. So the first thing it's gonna do is have us make a selection. So what is it we want to print? What I can just go ahead and choose my model as faras refinement. I tend to leave mine at medium, and it was fine. Make sure under your output that sent to three D print utility is selected, and here's a beautiful part. If you have any of these three D printing software and sell, it will actually go ahead and list them right out of the dialogue box here. So you can choose which three d printing utility you want to send this to so I can go ahead and let's say I want to send it to my maker. But I'm just gonna click, OK, and basically takes care of the rest. It'll open up maker by and actually place my model right on the bill plate. Now, let's see how I would I'll just walk through how I would approach this as I'm printing, you may have experience with this particular software. You mean that? But basically, the first thing I would do is I would choose my device, so I'm gonna go to device select type of device. Uh, I have a few printers, but let's have one ascended to Replicator two. I'm gonna make sure that's the one I have selected. Next, I can position this simply by using the's manipulators on the left side. If I want a place, this may be more to the front. I can do that or move it to the sides on every three D printing utility will have this sort of options to allow you to position rotate your objects. Um, you know, in this case, it positioned it perfectly. that's exactly have won a printed. But let's say, for example, that it was positioned like this. Well, you obviously are not gonna print it, you know, in that orientation. So you would want to go ahead and position it the way that it's actually going to be able to print correctly. Um, so you can play around with those What I actually like to do, especially with the maker bus software, is I'm good at it and just choose Otto layout all. And that will end up usually doing a good job in selecting the best orientation to three D print specific item. So just make sure that, you know, remember how a three D printer works. It relies on the bottom layers to support the top. Um, you know, when we're talking about this type of technology, the fused filament fabrication. So just make sure you know that it's position in a way that it's gonna be able to print next. I'll briefly talk about my settings. I usually stick with 0.2 millimeters. You know, you can go down a 0.1 or maybe point to 5.3. I usually try to print without a raft um, infill. You know, I usually am about 20% and in this case, I'm using P l. A. And my extruded temperature with maker by usually due to 30 you know, it's sometimes it's just a good idea to start with your defaults, you know, and then work your way from that. So, you know, honestly, I tend to use most of the defaults. The only thing I will usually changes. I usually don't print with a raft unless I need to. And maybe out, you know, play around either 10 to 20%. Or if I'm printing something, that's how I'll leave this and fill at zero. Um, but as far as a guide to using the three D printing utility, I just wanted to do a brief overview. You know, this I can go into a whole lesson one on how to use these, but you can find some good material either on that specific printing software's YouTube page of their website on and exactly how toe um, use all the different features. So next thing I would just click OK, and then that would export this to my printer, and usually I would save it in an SD card. So you would select your SD card, give it a title, um, between users. And then I would click Save. Um, so that's basically it. Let's try this again, but we'll use a different software. Um, let's say, for example, I want to used a cura instead of my maker bots offer. Well, I'm just gonna go ahead and choose care. Um, click OK, and it does the same thing. It will go ahead, open up, care for me, and it'll latest right into the bed of the printer. In this case, I have a multi maker to plus and same thing. We see the similar settings here where we can change. Choose our nozzle diameter. Um, our density are infill, you know? Are all our settings air here? So similar situation. The main point I want to show is how easy it is to go from fusion 3 60 to your printing software to organize your model and send it right to the printer. Um, again, if you want to use Ah, the multi maker software, which is Kira. If you go on the ultimate your website again, they have some good videos. I'm showing you how to used their specific software. I'm gonna go through one more option, and that's let's say, if you just want to save this as an STL, let's say you're printer, for example doesn't show on this list here, or you just want to save the model as an STL toe, upload it to a website, or maybe send it to a friend to three d print for you. Well, in that case, you all you do is uncheck the sent to three D print utility and you want to choose your model and click OK, And what that will do is it will open up this dialogue box and you're gonna choose, you know, wherever you want to save it. So I'm just gonna throw it on my desktop. Um, give it a name. And no, it is that the file type is as, um STL. So I can just click save now. I haven't STL file so I can open up the printing utility separate and go ahead and import it to their or I can, you know, uploaded to a website or do whatever I want with it. So that's basically yet, and that's how you get your model ready for three D printing. Aziz, You can see very straight forward process with fusion 3 60 They built it right into the software.
