1 00:00:00,000 --> 00:00:06,400 Ultimate Steam Deck. Here's the problem we have. You know this isn't a Steam Deck 2 00:00:06,400 --> 00:00:10,400 but same basic thing. You chuck it in your backpack and then the stick gets all 3 00:00:10,400 --> 00:00:15,560 smashed around but we have a solution. Jacob here from Creator Warehouse has 4 00:00:15,560 --> 00:00:20,640 designed a condom that goes over this. Now we don't have full production yet so 5 00:00:20,640 --> 00:00:28,720 instead we're getting a little tutorial in plastic casting. Alright. Shall I take 6 00:00:28,720 --> 00:00:35,080 it away? I don't think you really need to. Okay. What exactly do we do? Alright so 7 00:00:35,080 --> 00:00:41,080 we're going to, I'd start with putting down a covering. So I've got some wax 8 00:00:41,080 --> 00:00:44,480 paper right here that we just put in our work area. Mostly so that's easier to 9 00:00:44,480 --> 00:00:52,240 clean up afterward. Isn't this like a cooking show? And the idea in general is 10 00:00:52,240 --> 00:00:58,680 we've got these molds. Now in production a mold would be made out of aluminum or 11 00:00:58,680 --> 00:01:03,120 steel or something but these little 3D printed molds work okay for small 12 00:01:03,120 --> 00:01:06,440 quantities and prototyping. What we're going to do is we're going to screw the 13 00:01:06,440 --> 00:01:11,320 molds together so that they don't come apart and then we're going to fill them 14 00:01:11,320 --> 00:01:15,600 with the silicone resin and the resin we're going to be using is this mold 15 00:01:15,600 --> 00:01:22,520 max 40 stuff. There's a lot of different options. I like mold max. It's the 40 16 00:01:22,520 --> 00:01:27,240 stands for the hardness of it so the lower numbers tend to be a softer 17 00:01:27,240 --> 00:01:32,280 shore hardness and they're more like bubble gum or gummy bears whereas the 18 00:01:32,280 --> 00:01:37,680 harder ones are more like car rubber. So this stuff 40. It's a nice mix. I like it 19 00:01:37,680 --> 00:01:45,800 a lot. Let's take some bolts and put them through these holes and then we can screw nuts on the bottom base and torque it down so that we have a nice fit 20 00:01:45,800 --> 00:01:50,680 because if these, if the lids aren't tight then as we're injecting the resin 21 00:01:50,680 --> 00:01:54,400 the top is going to rise and we're going to get a bunch of flash around the 22 00:01:54,400 --> 00:02:01,880 edges. Oh yeah exactly. So got some nuts. I'll grab some sockets so that we can 23 00:02:01,880 --> 00:02:05,400 torque them down so we don't have to do it by hand and we've got five molds 24 00:02:05,400 --> 00:02:11,960 there. We prepared five for 3D printing. So you can get five of these guys. Cool. 25 00:02:11,960 --> 00:02:17,760 Yeah and it'll take about 24 hours for the resin to cure. This one doesn't want to go in. 26 00:02:17,760 --> 00:02:22,840 It's a bit of a stiff fit. I admit I designed that for m6 bolts which are 27 00:02:22,880 --> 00:02:30,480 six millimeters. Those are quarter inch bolts which are 6.35. So they're a 28 00:02:30,480 --> 00:02:34,040 little bit too big. So what's the torque rating on these? I'm guessing it's, you 29 00:02:34,040 --> 00:02:42,040 know, very specific. Low enough that we don't crush the plastic. Hmm. These are 30 00:02:42,040 --> 00:02:50,560 3D printed. They're not steel. So torque to yield. Quarter turn, 94 pounds. Torque 31 00:02:50,600 --> 00:02:55,800 to I yield, you mean? Let's see here. I'm kind of curious now. What the torque is? 32 00:02:55,800 --> 00:03:04,640 If I had to guess, 10, 20. Yeah. Shall we run a destructive test and have four molds? 33 00:03:04,640 --> 00:03:09,520 Let's see how 10 feels. Okay. 34 00:03:09,520 --> 00:03:27,120 Need a wrench. What is this? 11? You could borrow. I like how we're using a torque wrench. When 35 00:03:27,120 --> 00:03:32,600 in doubt, use the biggest tool you have. So realistically what this means is if we only 36 00:03:32,720 --> 00:03:38,720 can apply five foot pounds of torque, we're not getting the full recommended, whatever 37 00:03:38,720 --> 00:03:42,920 it is, five or 10 tons of clamping force that you should on injection molding. But we're 38 00:03:42,920 --> 00:03:48,920 not getting that anyways because it's a plastic mold. Let's see. Five foot pounds. Oh, I 39 00:03:51,920 --> 00:03:58,640 think that's too much. Wow, that's very low torque. It's not much. I sometimes just hand 40 00:03:58,680 --> 00:04:03,240 tighten it. I brought it as a joke, but now I'm actually surprised how little it takes. 41 00:04:03,240 --> 00:04:14,360 It's not much. Now, if we 3D printed these solid or out of polycarbonate, maybe this is just 42 00:04:14,360 --> 00:04:25,600 PLA. Remember when I said these were fast? Three foot pounds. This wrench probably doesn't even do 43 00:04:25,640 --> 00:04:33,800 three foot pounds. Oh, there we go. Equipped. Three foot pound feels pretty good. That's what 44 00:04:33,800 --> 00:04:40,000 we're doing. All right. I'll make a note. Three foot foot pounds is the recommended torque. Yep. 45 00:04:40,000 --> 00:04:45,320 We'll write that up in the owner's manual. Now, this is a process you could use for injection 46 00:04:45,320 --> 00:04:50,920 molding or prototyping lots of stuff. 3D printed mold, put the silicone in whatever shape you 47 00:04:50,920 --> 00:04:58,160 want. It doesn't have to be our design. It could be something else. Okay, I'm going to put away 48 00:04:58,160 --> 00:05:04,640 this thing. You having too much fun? Well, I accomplished one in the time that you did four. 49 00:05:04,640 --> 00:05:11,480 So that's okay. Apparently sizes into everything. All right. This is probably when we should be 50 00:05:11,480 --> 00:05:18,280 putting on gloves because we're going to make a bit of a mess, I think. And what we're going to be 51 00:05:18,280 --> 00:05:26,680 doing is this silicone resin comes in two parts. There's the, I guess, part A it is. And then there's 52 00:05:26,680 --> 00:05:33,160 the small hardener, part B. And it's mixed at a 10 to 1 weight by weight ratio. So if you put in 53 00:05:33,160 --> 00:05:40,600 30 grams of this stuff, you'll want to put in 3 grams of the hardener. Okay. We've got the scale 54 00:05:40,600 --> 00:05:47,600 here. And I've got some nice little disposable cups that we can use for this. And I'll go grab one 55 00:05:47,600 --> 00:05:53,760 of our stirring rods to mix it all up afterward. These are stir rods and not skewers that might 56 00:05:53,760 --> 00:06:00,360 have been picked up at a grocery store. I have like a thousand dowel pins. You serious? Wooden 57 00:06:00,360 --> 00:06:06,360 dowel pins. Yeah, wooden dowels. Oh, nice. Are they stiff? Well, I bought them for exactly this. 58 00:06:06,360 --> 00:06:16,800 There it is. So that's not a thousand, but those are great. Let's use those. All right. Yeah, 59 00:06:16,800 --> 00:06:21,440 the resin is quite thick, or the silicone is quite thick. So having a stiffer stir rod is way nicer. 60 00:06:21,440 --> 00:06:29,920 Okay. All right. So I'd say that this syringe, so what we're going to do after we mix it is we're 61 00:06:29,920 --> 00:06:33,920 going to put it in the syringe and then put it in the vacuum chamber, suck all the bubbles out, 62 00:06:33,920 --> 00:06:40,000 essentially, and then immediately put the silicone into the molds. Now you don't want to fill this 63 00:06:40,000 --> 00:06:46,040 all the way to the top because as the bubbles are being released and you're degassing the silicone, 64 00:06:46,280 --> 00:06:50,600 it's going to froth and it's going to expand. And if it's all the way to the top, it's going to 65 00:06:50,600 --> 00:06:57,320 immediately expand out into our vacuum chamber, make a huge mess. So I'd say we should probably put 66 00:06:57,320 --> 00:07:03,720 in 15, maybe 20 milliliters and then hope that that's not going to expand all the way to the top. 67 00:07:03,720 --> 00:07:10,920 It's a bit of a guessing game. We might overshoot. How about we do, it's 10 to 1. So what if we do 68 00:07:10,920 --> 00:07:17,000 20 grams of this and then 2 grams of the hardener and then that's 10 to 1, I think. 69 00:07:18,520 --> 00:07:29,000 Yeah. So you'll want to mix this beforehand because sometimes some of the things can settle 70 00:07:29,000 --> 00:07:34,120 and it's good to have it nice and mixed. Wait, do we not have to use mold release in this? 71 00:07:34,600 --> 00:07:41,560 Yes, we should. So far it's been okay. All right. That's not actually always true. It's not always 72 00:07:41,560 --> 00:07:48,920 been okay. But I think we can risk it. All right. Yes, you should use mold release. You can use, 73 00:07:48,920 --> 00:07:52,680 they've got these wax sprays that you could put on, but we'll have to remove all the bolts, 74 00:07:52,680 --> 00:07:58,680 or you can use talcum powder is also good as well. For larger molds or for a resin that sticks really 75 00:07:58,680 --> 00:08:03,000 well, like fiberglass resin or a lot of other two-part epoxies, that's way more important. 76 00:08:03,560 --> 00:08:09,240 This is silicone, which while it adheres relatively well to itself as it's curing, 77 00:08:09,240 --> 00:08:13,240 silicone doesn't tend to adhere to other materials as easily. So you can peel it out 78 00:08:13,240 --> 00:08:20,600 pretty easily. It's sort of like if you're casting something soft, it's often a good 79 00:08:20,600 --> 00:08:24,680 idea to have a hard mold because it keeps it rigid. Whereas if you're casting something hard, 80 00:08:25,320 --> 00:08:29,800 then it's a good idea to have a soft mold. So that's why if you wanted to cast a hard plastic 81 00:08:30,360 --> 00:08:34,520 resin, you might use a silicone mold. Whereas right now we're doing the reverse. 82 00:08:35,800 --> 00:08:39,240 It makes it quite easy to remove things and then you can maintain good 83 00:08:40,600 --> 00:08:45,080 dimensional tolerances and it's great. All right. Will we have any shrink when it's in here? 84 00:08:47,960 --> 00:08:52,920 This stuff's pretty good. It doesn't shrink very much, but that hasn't really been much of an issue. 85 00:08:53,160 --> 00:08:59,960 Okay. Yeah, I guess the dimensional tolerances of a joystick condom is not like a thousandth of an 86 00:08:59,960 --> 00:09:05,960 inch. Yeah, they've got to accommodate different sizes. Things shrink sometimes. 87 00:09:07,560 --> 00:09:15,880 We'll have to make the magnum for like... Oh no. Yeah, big thrust master. That's definitely 88 00:09:15,880 --> 00:09:21,240 what it's going to be called. Your whole racing sim just encased in silicone. 89 00:09:23,880 --> 00:09:28,680 All right. So this kind of flows like honey. So I can kind of just... Weird. I know. It is weird. 90 00:09:30,840 --> 00:09:36,760 This scale only measures down to a gram. However, while this has a density that is very different 91 00:09:36,760 --> 00:09:43,560 from water, the hardener has a density that's very close to water. What that means is you can pretend 92 00:09:43,560 --> 00:09:52,120 that two milliliters is two grams. So I'm going to... Again, I'm cheating. It said you're supposed 93 00:09:52,200 --> 00:09:59,000 to measure weight by weight. We're going to do weight by volume mix. It's easier given the tools. 94 00:09:59,560 --> 00:10:04,840 Should we just buy a better scale? Yes. I've requested one. Okay. It hasn't come in yet. 95 00:10:05,880 --> 00:10:13,400 In fact, I've requested it twice. And then this syringe does... That's a one milliliter syringe. 96 00:10:13,400 --> 00:10:17,800 So we can just fill it twice. And now that the hardener has been added to the silicone, 97 00:10:18,440 --> 00:10:24,120 we're on a time limit. We could always just go back before this, but you're not going to get 98 00:10:24,120 --> 00:10:28,760 that out. And that silicone is going to harden in 12 hours. Oh, okay. So at this point, we need to 99 00:10:30,760 --> 00:10:36,920 mix it, which is why the mixing stick is nice. Yeah, you can use that one. I found that mixing 100 00:10:36,920 --> 00:10:41,560 it gently at first and then more aggressively once it's a little bit mixed makes it easier than 101 00:10:41,560 --> 00:10:49,000 you don't splash the part two as much. You can't go wrong. Just mix it like crazy. Once the color 102 00:10:49,000 --> 00:10:53,640 is all pretty well blended, that should be good. However, since it's thicker, you're going to find 103 00:10:53,640 --> 00:10:59,880 that as you're mixing it, if you don't scrape the silicone right off the edges, the bottom and the... 104 00:11:00,840 --> 00:11:04,840 Can I call them walls of the cup? Then you're going to get silicone around the edge that is not 105 00:11:04,840 --> 00:11:12,120 mixed. Okay. If you have a clear cup, which we don't, then you can really see that well. And it 106 00:11:12,120 --> 00:11:21,720 looks a little bit like cosmopolitan ice cream. Oh, this is probably good. I'd say so. Yeah, 107 00:11:21,720 --> 00:11:29,320 and then we can pour that in here. I'm letting you do it because I don't know how to do this well either. 108 00:11:35,320 --> 00:11:37,080 Mmm, delicious. 109 00:11:40,920 --> 00:11:42,440 The forbidden mint ice cream. 110 00:11:44,760 --> 00:11:52,360 I wouldn't eat this, but okay. Is this food safe silicone or silicone? 111 00:11:55,560 --> 00:12:02,200 I'm pretty sure this stuff is tin cure, which is not. So it's fine to touch and handle once it's 112 00:12:02,280 --> 00:12:09,320 cured. There is other types of silicone that are platinum cured, and those tend to be a little bit 113 00:12:09,320 --> 00:12:15,240 safer if you're going to have them in contact with skin. I would need to check if they're food safe, 114 00:12:15,240 --> 00:12:23,000 though. Okay. But this one is not. And even if it's food safe, you still shouldn't eat it. 115 00:12:25,080 --> 00:12:29,240 Do we get a lot of it? There's only so much we're going to get. We might have to do this in 116 00:12:29,320 --> 00:12:35,080 multiple runs. No, we're doing it all at once. Let's do it. So the reason that we don't have just 117 00:12:35,080 --> 00:12:39,720 like a large plastic cup to do all of this at once and then put it in the syringe after? 118 00:12:41,000 --> 00:12:47,480 I found that the process of pouring it into the syringe adds a lot of bubbles to the silicone. 119 00:12:48,440 --> 00:12:53,320 So you put it straight into here, you degas it in here, and then it immediately goes in there. 120 00:12:53,320 --> 00:12:56,440 That makes sense. And then you don't have to have a transfer step. 121 00:12:59,240 --> 00:13:00,920 There we go. And you can get a view from the top. 122 00:13:09,480 --> 00:13:12,520 So hopefully we didn't overfill this because it's going to start to froth, 123 00:13:13,080 --> 00:13:17,960 and the silicone is going to expand upward. And if we left enough space, 124 00:13:17,960 --> 00:13:24,840 it will not expand out of the tube. If we didn't, then I've got more cleanup to do afterward. 125 00:13:25,800 --> 00:13:33,640 Oh, perfect. Oh, yeah. Okay, cool. We're at a near vacuum. So I'm just going to hold that there 126 00:13:33,640 --> 00:13:39,960 and turn off the pump. A lot of these pumps can continuously drop vacuum, but this one, 127 00:13:39,960 --> 00:13:47,080 it doesn't like to run for too long. All right. Okay, let's just let a bit of air out. 128 00:13:49,800 --> 00:13:54,120 All right, collapse foam, and then we'll pull another vacuum. So when you collapse it, 129 00:13:54,120 --> 00:13:59,640 the bubbles can just pop. All right. So what I just did is I just drew a vacuum. 130 00:14:00,360 --> 00:14:06,040 Okay. Don't say so. That's illegal in this company. I'm sorry. So anyways. 131 00:14:09,560 --> 00:14:14,280 Shoot, now I don't know how to start my second. What we just did was we drew a full vacuum, 132 00:14:14,280 --> 00:14:21,640 then we released some of it, and that causes the bubbles to pop and disperse, and then they come out 133 00:14:21,640 --> 00:14:26,280 of the silicone, and then you can draw another vacuum just to get the rest of them. And usually, 134 00:14:26,280 --> 00:14:29,960 I'll do that a couple of times just to make sure all the bubbles are gone. 135 00:14:33,160 --> 00:14:39,560 Tasty. Now, this particular silicone cures pretty slowly, so we can do this fast. There are others 136 00:14:39,560 --> 00:14:43,720 where you can't take this much time, and you have to go quick. Is that condensation coming out of 137 00:14:43,880 --> 00:14:52,520 this? What is that? Is it smoking? I think it's smoking. You know what? I think this is degassed 138 00:14:52,520 --> 00:15:04,680 enough. Okay. So remember when I said I don't like to leave this pump running for too long? 139 00:15:05,480 --> 00:15:11,880 That's why. Yeah. So now we can just inject this into the molds. So what we've got 140 00:15:12,520 --> 00:15:18,280 is we've got, goodness, I've forgotten the name of all of them, injection gate. That's the big one 141 00:15:18,280 --> 00:15:23,800 in the middle, and then we have smaller gates for releasing air out the sides. Wait, wait, wait, wait. 142 00:15:23,800 --> 00:15:27,000 Can you take it out and put it back on? Okay. Well, it's covered in silicone now, but... 143 00:15:29,400 --> 00:15:35,240 It's all right. I'm going to keep applying pressure until I see silicone come out the vent holes, 144 00:15:35,240 --> 00:15:39,960 and then I know the whole mold is full. Okay. There it is. Okay. It's come out of four of them, 145 00:15:39,960 --> 00:15:44,840 but it hasn't come out of the middle ones yet. Okay. Now it's come out of all of them. 146 00:15:45,960 --> 00:15:50,040 Excellent. Now I can remove that and move to the next one, 147 00:15:52,200 --> 00:15:57,560 and then apply pressure. Oh, okay. Apply pressure again, and it's going to come out. You've got to 148 00:15:57,560 --> 00:16:02,040 wait until the silicone comes out of all of the vent holes, because if it only comes out of some of 149 00:16:02,040 --> 00:16:08,680 them, there's still a bubble underneath the others. Okay. Yeah. So all right. There we go. It's coming 150 00:16:08,680 --> 00:16:18,280 out of all four. Move over, and I think we've run out. Mix up more. Let's mix up more. Here we go. 151 00:16:21,080 --> 00:16:26,280 I wish I had a funnel. It was like Linus' personal pump. Oh, is that where it came from? Oh, so it 152 00:16:26,280 --> 00:16:31,640 wasn't new. Yeah. It was probably very much abused by him. Yes. We managed to catch it before all 153 00:16:31,640 --> 00:16:39,320 the silicone came out. I'm going to prop that up with something. How about a one, two, three block? 154 00:16:39,320 --> 00:16:43,000 Sure. There we go. Now it's not going to fall over. 155 00:16:48,920 --> 00:16:53,000 I suppose we could have put a bit more in, because it only went up to about 30. 156 00:16:57,400 --> 00:16:58,760 Okay. Let's do this quickly. 157 00:17:02,360 --> 00:17:08,200 It's probably fine. It's fairly easy. Okay. 158 00:17:14,280 --> 00:17:20,600 That's probably good. There we go. Next one. So I, oh, okay. Let's just start. 159 00:17:21,000 --> 00:17:31,400 So for this one, I'm hoping that because we had a break between, we're not going to have a bubble 160 00:17:31,400 --> 00:17:37,720 between two layers of silicone. So I might push a little bit extra through to see if there was a 161 00:17:37,720 --> 00:17:44,120 bubble in there. That's probably fine. Probably. It's really hard to tell. Wait, four holes? 162 00:17:44,120 --> 00:17:52,120 Wait, four holes? And eight holes. Okay. A bubble probably would have come out by now. 163 00:17:55,720 --> 00:18:02,920 What's up? Hi. Hi. So some of the SLA's you can print with clear resin, which is really cool. 164 00:18:02,920 --> 00:18:08,200 Oh, you'd be able to see it. Yeah. We should have done that. Oh, that would have been really cool. 165 00:18:08,920 --> 00:18:16,040 I don't know if we have a crystal clear resin for the SLA. Is it? Okay. I think it's probably done. 166 00:18:18,520 --> 00:18:20,760 Oh, just a little bit left. Hopefully we don't run out. 167 00:18:25,640 --> 00:18:29,560 No, I think we're out. Oh, well. 168 00:18:29,800 --> 00:18:41,320 Okay. Well, that's four. Should we do it one more time? Yeah. Okay. There we go. So now we just 169 00:18:41,320 --> 00:18:47,640 leave these out of the way for 24 hours. Yep. Or 12 is probably okay. 170 00:18:50,440 --> 00:18:56,120 Thank you for watching this flow plane exclusive. Now we get to see Jamie.
