WEBVTT 00:00:00.000 --> 00:00:11.480 Boy! My mechanical room is a mess! I've never been more proud. A year ago, I bought my kids 00:00:11.480 --> 00:00:16.440 a 3D printer for Christmas, and it was one of my most devious parenting maneuvers yet. 00:00:16.440 --> 00:00:22.000 See, they thought I was giving them the means to make toys and fidget gadgets, but what 00:00:22.000 --> 00:00:27.560 I was actually giving them was some motivation to learn a little bit about 3D printing and 00:00:27.560 --> 00:00:32.200 3D modeling, which I hoped would serve as a catalyst to getting them a little bit more 00:00:32.200 --> 00:00:38.240 curious about the technology around them and how it actually works. But it has gone so 00:00:38.240 --> 00:00:43.240 far beyond that. I've been selling 3D printed fidgets to classmates. I went to the Entrepreneur 00:00:43.240 --> 00:00:49.520 Fair last week at school and made 200 bucks, which puts my total at 500 now. Even the teachers 00:00:49.520 --> 00:00:55.520 are apparently getting in on the action. These are apparently super popular with the adults. 00:00:55.520 --> 00:00:59.520 This is your number one seller right now, right? Easily number one seller. 00:00:59.520 --> 00:01:04.000 Naturally, when I learned that the storm that hit our mechanical room was an entrepreneurial 00:01:04.000 --> 00:01:08.880 hurricane, the first thing I did was bring home some idle 3D printers and the PrusaCore 00:01:08.880 --> 00:01:11.880 one that Joseph, I call him Joseph. 00:01:11.880 --> 00:01:15.560 Hmm, are we actually Matt? 00:01:15.560 --> 00:01:21.960 Sent over for evaluation. Unfortunately, the second thing I didn't do is organize our 00:01:21.960 --> 00:01:28.640 newly planted print farm. And we have learned extremely quickly that scaling up takes more 00:01:28.640 --> 00:01:35.200 than just printers. We have got to fix this. And there's no time to lose, because next 00:01:35.200 --> 00:01:40.680 week is round two of the Entrepreneur Fair, and Randy here sold almost all of the inventory 00:01:40.680 --> 00:01:46.320 that he prepared for the first one, just like Colton's team sold this segue to our sponsor. 00:01:46.320 --> 00:01:53.640 Dad, we're out of red filament again. Okay, we could talk about filament later, because first, there are a lot of things to 00:01:53.640 --> 00:01:58.600 address here. Some of them are obvious at the surface, like the total lack of organization 00:01:58.600 --> 00:02:05.000 of our workspace, but some of them are a little deeper, like the destroyed printhead on our 00:02:05.000 --> 00:02:08.280 OG machine, this bamboo P1S. 00:02:08.280 --> 00:02:15.520 That wasn't my fault. That was my sister's. Well, let's start by fixing that. As something of a 3D printing novice, hot ends are something 00:02:15.520 --> 00:02:20.040 I don't really know a ton about, and it's a surprisingly deep topic. We might need a 00:02:20.040 --> 00:02:25.920 bit of help. You laid out your requirements, and I chose BQ's Panda Revo hotend with a mix of brass 00:02:25.920 --> 00:02:30.280 and obsidian nozzles and in a variety of nozzle sizes. These are going to help you change your 00:02:30.280 --> 00:02:35.560 nozzles really fast, and obsidian is great for abrasive materials. Your Core 1 doesn't 00:02:35.560 --> 00:02:39.680 really need this, because it's got a pretty good system already. You just kind of loosen two screws. 00:02:39.680 --> 00:02:43.200 This sounds amazing. Just one question. Who the heck are you? 00:02:43.880 --> 00:02:48.560 I'm Sean. I worked for a couple 3D printer manufacturers. My last job was as an editor 00:02:48.560 --> 00:02:52.680 at a 3D printing publication, and I work here now. You know me. You drilled me on Star Wars 00:02:52.680 --> 00:02:56.920 a couple of days ago. Cool. This has been out of commission for almost two weeks. What did you guys do to 00:02:56.920 --> 00:03:00.760 it? Like you got a whole bunch of filament on it, and then when you were trying to remove 00:03:00.760 --> 00:03:06.280 it with a torch, you like killed it? Yeah, somehow. We melted the temperature probe by accident. 00:03:06.280 --> 00:03:10.080 Okay. Let's go ahead and throw the new one on. Theoretically, this is as simple as just 00:03:11.080 --> 00:03:14.960 propping it on there, and then we're good to go. Oh, wow. Is it really that easy? Are 00:03:14.960 --> 00:03:18.320 you sure you don't want to put the fan on first? Yeah, we should probably do that. 00:03:18.320 --> 00:03:22.680 Okay. And we should probably call out the precision screwdriver from LTTstore.com. Great 00:03:22.680 --> 00:03:26.760 for these types of jobs. I don't know how he managed to drop the screw, because it's 00:03:26.760 --> 00:03:31.480 magnetic, but like father, like son, I guess. Also, we've got new sizes now. So we've got 00:03:31.480 --> 00:03:39.280 the obsidians in .4 and .6, and we got a brass nozzle, not just in .4, but also .25. So if 00:03:39.280 --> 00:03:43.680 you wanted to print finer stuff on this one, then you could. It'll take longer, but if 00:03:43.680 --> 00:03:47.840 people are willing to pay a little bit more for a finer print, then hey. 00:03:47.840 --> 00:03:57.360 Who cares? Yeah, exactly. Can I see? Yeah, just needs man strength, or rather just needs being willing 00:03:57.360 --> 00:04:00.800 to force things a little bit. It's good. I don't want to break the new nozzle. 00:04:00.800 --> 00:04:05.440 Yeah, I don't want to break the new nozzle either. These are way more expensive than 00:04:05.440 --> 00:04:09.360 our old ones. The obsidians are like twice the price of a brass nozzle. 00:04:09.360 --> 00:04:13.360 How much are they? Around $75. $75 per nozzle? 00:04:13.360 --> 00:04:18.920 Wow. So the deal we have with him, and the girls for that matter, is we have no problem encouraging 00:04:18.920 --> 00:04:23.720 their entrepreneurship. We're willing to provide the equipment, but consumables, they need 00:04:23.720 --> 00:04:29.480 to reimburse us for. And I haven't figured out where hot ends figure into this. 00:04:29.480 --> 00:04:33.120 I'm on the side of equipment. Yeah, you would be. 00:04:33.120 --> 00:04:37.080 Oh, now's a good time to mention that we got some new desiccant that you can put in your AMS. 00:04:37.080 --> 00:04:42.440 Finally got better desiccants. These are the silica gel desiccant packs from Wise Dry, and they are rechargeable, 00:04:42.440 --> 00:04:45.880 which means that they'll change color when they're too wet, and then you can put them 00:04:45.880 --> 00:04:51.280 in a microwave, a stove, or just your filament dryer to recharge them and put them back in. 00:04:51.280 --> 00:04:57.960 That's great. I hate low quality desiccants. You're going to want to take these out, and you're going to want to open that and take 00:04:57.960 --> 00:04:59.960 out the desiccant that's already in there. 00:05:01.480 --> 00:05:05.360 Great. And that's probably old. It feels moist. Yeah. 00:05:05.360 --> 00:05:12.440 Oh, wild. This is way more than I need. Yes, but it's great that you can put these packs in your vacuum sealed bags, and that's 00:05:12.440 --> 00:05:19.040 going to help keep the filament dry while you're storing it. What the Sam heck happened here? You left it loaded with red, but you took the red spool 00:05:19.040 --> 00:05:22.240 out. Yeah, because I needed the red. 00:05:22.240 --> 00:05:26.760 I noticed, by the way, that you only caught me for the weight of your finished prints. 00:05:26.760 --> 00:05:29.760 Yeah. What happens to all of this? I don't know. 00:05:29.960 --> 00:05:34.760 Want to go ahead and fire up a test print? Sure. Just don't forget we have a 0.6 millimeter nozzle in there now. 00:05:34.760 --> 00:05:39.800 Other than that, the obsidians, obsidians, however you pronounce them, they're drop-in 00:05:39.800 --> 00:05:43.040 replacements. There's not going to be a preset for obsidian nozzles. 00:05:43.040 --> 00:05:46.520 I would stick with E3D's high flow profiles. 00:05:46.520 --> 00:05:51.000 The thing to keep in mind is when you're using a bigger nozzle, you may need more heat to 00:05:51.000 --> 00:05:56.760 make sure that it gets through the entire thing, but there's a pretty good melt zone 00:05:56.880 --> 00:06:00.000 on these nozzles, so you should be fine for 0.6. 00:06:00.000 --> 00:06:04.120 Now let's go ahead and print a Benchy. Oh, after calibrating. 00:06:04.120 --> 00:06:08.320 Oh. 26 minutes. You know what? 00:06:08.320 --> 00:06:14.880 That's a perfect time for us to do something about the state of this room. Oh, you thought it was just all fun and games upgrading your 3D printers today? 00:06:14.880 --> 00:06:18.480 Yeah. So making space for the PrusaCore 1? 00:06:18.480 --> 00:06:23.080 That was no biggie. I just shoved this guy over and then plonked it on there. 00:06:23.560 --> 00:06:27.960 When logistics offered up these three bamboo X1C's that we retired from our print farm 00:06:27.960 --> 00:06:33.680 at the office in favor of more Prusas, there was no plan. 00:06:33.680 --> 00:06:37.480 Okay. Wait, why am I doing this? 00:06:37.480 --> 00:06:41.560 Kids! Guess who got a special assignment? 00:06:41.560 --> 00:06:45.440 Me. Both of you, you're both right. Time to clean this place up. 00:06:45.440 --> 00:06:49.800 I want all of the garbage dealt with and anything that isn't garbage I would like organized 00:06:49.800 --> 00:06:54.600 in a nice tidy little pile. Why don't we put it in this toolbox that Randy made? 00:06:54.600 --> 00:07:04.400 Okay. Chop chop. While the kids are working on that, Sean and I have a few things to deal with too. 00:07:04.400 --> 00:07:08.920 We've got to build this shelf and I've got to get all of my camping stuff out of this 00:07:08.920 --> 00:07:21.440 story term. If you're going to take the printers out, then what are you going to put in here? 00:07:22.440 --> 00:07:29.080 I'm going to put a big battery that keeps our house powered in power outages. 00:07:29.080 --> 00:07:32.080 Our test print failed. It doesn't know what filament to use. 00:07:32.080 --> 00:07:38.160 Oh, you know what? Honestly, that's probably fine. Why don't we just move this out first and then we'll do the test print out there? 00:07:38.160 --> 00:07:44.320 Oh, this is cool. Thanks to the power of our magnetic cable management, it's just one cord. 00:07:44.320 --> 00:07:50.320 See? Using our power bar holders like that, using our arches like that. 00:07:50.320 --> 00:07:54.200 Good stuff. LTTstore.com. All right. 00:07:54.200 --> 00:07:57.200 Let's go, boy. Oh, hold on. We're not clearing the door. 00:07:57.200 --> 00:08:00.560 We're like a BC trucker. A little bit of local humor for you. 00:08:00.560 --> 00:08:03.640 This space is not as big as I thought. 00:08:03.640 --> 00:08:07.800 Well, you're going to use the space. What do you think we should do? 00:08:07.800 --> 00:08:10.880 Have just two racks, one here, one there, or whatever. 00:08:10.880 --> 00:08:15.560 We'll make our best effort to line up all the printers on this rack and then along this 00:08:15.560 --> 00:08:24.640 wall right here. And then this shelf, I want you to organize all the filament, tools, desiccant, consumables 00:08:24.640 --> 00:08:30.840 as best you can. Now, before we put any printers on to here, there is something that I wanted to do first 00:08:30.840 --> 00:08:34.200 and that is put some of this MDF on here. 00:08:37.200 --> 00:08:41.560 All right, shelves are in place. Time to find out if we can get all three of the X1Cs on here. 00:08:41.560 --> 00:08:49.360 I kind of doubt it. For each 15 and a half inches in this shelf is like 46, so it might be hanging off, but 00:08:49.360 --> 00:08:52.680 it's okay. How do you want to handle the AMSs? 00:08:52.680 --> 00:08:57.120 Would you rather have one printer that can do many colors or more printers that can 00:08:57.120 --> 00:09:01.440 do a handful of colors? More printers that can do a handful. Oh man, I was afraid you were going to say that. 00:09:01.440 --> 00:09:06.440 Now let's just make sure they all fit on the shelf and a one and a two. 00:09:06.440 --> 00:09:09.800 We're not going to get a third on there, but not with that attitude. 00:09:09.800 --> 00:09:13.600 Oh, did we talk about fumes at all? No, not yet. 00:09:13.600 --> 00:09:18.880 Oh, okay. Do you want to do that? Well, we took this out of your mechanical room, which is a separate environment from 00:09:18.880 --> 00:09:22.280 the rest of your house, right? Yes. Okay. 00:09:22.280 --> 00:09:26.360 And in here, you're not. So we're going to want to put an air purifier in there. It's not a perfect solution. 00:09:26.360 --> 00:09:31.880 You shouldn't use engineering grade materials or ABS, things that have styrene in them. 00:09:31.880 --> 00:09:35.880 PLA, PETG. They're generally considered to be safe. 00:09:35.880 --> 00:09:39.040 Okay. And shout out HouseFresh, who we collaborated with a little while ago. 00:09:39.040 --> 00:09:41.880 I'm going to go to them and I'm going to find an air purifier. 00:09:42.480 --> 00:09:44.480 See? Called it. 00:09:45.480 --> 00:09:49.280 It's definitely going to fit. You know what? You're right. 00:09:49.280 --> 00:09:53.720 That's a good call. They are like practically touching each other. 00:09:53.720 --> 00:09:57.040 Look at this edge. It's like just hanging over it. It's perfect. 00:09:57.040 --> 00:10:00.200 Uh, let's move the AMS's down to the bottom. 00:10:00.200 --> 00:10:05.280 One of the major challenges for me organizing the space was that it has to be children accessible. 00:10:05.280 --> 00:10:10.880 And he's pretty big now, but she's not. So we can't have her changing spools up here. 00:10:10.880 --> 00:10:17.000 Yeah. Okay. Hey, that could work. 00:10:17.000 --> 00:10:20.000 Now everything reaches. 00:10:20.000 --> 00:10:23.520 It's much more organized than before. Actually, that's that. This is way better. 00:10:23.520 --> 00:10:26.520 So then. Oh, dude. No, no. 00:10:26.520 --> 00:10:30.520 Hold on. What was I thinking before? What was I thinking before? 00:10:30.520 --> 00:10:33.520 But. Hello. A boom. 00:10:33.520 --> 00:10:36.520 Oh, yeah. 00:10:36.520 --> 00:10:39.800 Got right there. 00:10:39.800 --> 00:10:44.460 That's the 3D printing space money shot. I'm going to start the test print again. 00:10:44.460 --> 00:10:48.720 Go for it. Something I noticed, you've been printing with your doors closed, right? 00:10:48.720 --> 00:10:54.480 Yeah. Okay. With the bamboo lab machines, bamboo lab recommends that you have the door open and also the top 00:10:54.480 --> 00:10:58.960 if you're doing best practices, but I would at least prop the door open when you're printing 00:10:58.960 --> 00:11:02.880 with PLA. Otherwise it might get too hot inside for that kind of material and you won't get the 00:11:02.880 --> 00:11:08.640 best prints you can. Now's a good time to talk about one of the other challenges that we've had lately too. 00:11:08.640 --> 00:11:12.400 Even on the core one, which has been our most reliable for bed adhesion, we've had 00:11:12.400 --> 00:11:15.840 some pretty spectacular print failures. 00:11:15.840 --> 00:11:21.280 Now print beds are a consumable, but that doesn't mean that the ones that we have are 00:11:21.280 --> 00:11:24.680 bad or broken or anything. They should last a very long time. 00:11:24.680 --> 00:11:28.320 So to avoid this in the future, couple things. 00:11:28.320 --> 00:11:33.520 Make sure you've calibrated your printer recently. These bamboos level themselves with pressure sensors in the bed. 00:11:33.520 --> 00:11:38.800 Next, we need to make sure we're cleaning properly in between prints. Remember how I told you that you could clean them with isopropyl alcohol? 00:11:38.800 --> 00:11:44.240 Yeah. Okay. Turns out that for the textured beds, that's actually not correct. 00:11:44.240 --> 00:11:49.440 Okay. Instead, we want to use a mild detergent and water because that'll help us really get into 00:11:49.440 --> 00:11:53.640 the grooves and make sure that we get any oils or any contaminants off them. 00:11:53.640 --> 00:11:57.680 For smooth beds, we just got a bamboo smooth plate so you can try this out if you want 00:11:57.680 --> 00:12:01.160 a different texture on the bottom of your prints or if you're having adhesion issues. 00:12:01.160 --> 00:12:06.160 Isopropyl, totally fine, but you never want to use it for these. 00:12:06.320 --> 00:12:12.720 These are super tack cool plates. These are super cool and tack. 00:12:12.720 --> 00:12:17.880 The point is neither frayed nor I have tried them before, but in theory, they actually 00:12:17.880 --> 00:12:22.360 allow you to print cooler, which can save you heating time and cooling time, which is 00:12:22.360 --> 00:12:26.840 pretty key because another thing that I don't think you knew is that pulling parts off of 00:12:26.840 --> 00:12:30.920 a hot bed can actually cause the part to warp. 00:12:30.920 --> 00:12:38.480 So we don't want to do that. So now we've got a bunch of extra plates. So what you can do is you can do your print, pull your plate off, print and all, throw a 00:12:38.480 --> 00:12:41.600 clean plate on and start your next print and wait for it to cool down. 00:12:41.600 --> 00:12:46.200 I didn't know you had to let it cool down. I've been taking it off hot in the past either. 00:12:46.200 --> 00:12:50.240 But hey, I mean, we're new to this is how we learn. There are other ways you can improve bed adhesion. 00:12:50.240 --> 00:12:55.600 You can try running five to 10 degrees hotter for your first layers or you could try making 00:12:55.600 --> 00:13:01.120 sure your auxiliary fan is off. Finally, there's good old fashioned glue. 00:13:01.120 --> 00:13:04.680 Another PVP glue acts as a bonding agent for first layers. 00:13:04.680 --> 00:13:09.240 You can use like regular Elmer's glue you get from any store, but I like the 3D printing 00:13:09.240 --> 00:13:13.160 specialized liquid stuff because it makes consistent application easy. 00:13:13.160 --> 00:13:16.800 Glue also makes it easier to take your prints off of a build plate because though it's an 00:13:16.800 --> 00:13:21.720 extra bonding layer, it's also a separate layer from that stiffer surface of the print 00:13:21.720 --> 00:13:28.920 bed. It won't stop severe warping, but it will help those tricky small first layers and tiny 00:13:28.920 --> 00:13:33.320 features. Cool. You don't need to clean after every print. 00:13:33.320 --> 00:13:39.200 I would say clean and reapply every 10 prints or so or just see how a new application works 00:13:39.200 --> 00:13:44.840 if you're having trouble. Perfect. Now it's time to talk about something that bothers me a lot more than it bothers my kids. 00:13:44.840 --> 00:13:49.520 These multi-filament AMS systems, they're super cool for multicolored printing, but 00:13:49.520 --> 00:13:52.640 they waste so much filament. 00:13:52.640 --> 00:13:58.000 The last time that I tested X1C printing with an AMS on its default settings, I printed 00:13:58.000 --> 00:14:04.560 a 125 gram model with three different filaments and it wasted over 500 grams between the tower 00:14:04.560 --> 00:14:08.360 and the purge. Yeah. Now, fortunately, this is tunable. 00:14:08.360 --> 00:14:11.800 The first thing we need to do is turn on long retraction. 00:14:11.800 --> 00:14:17.240 This reduces the amount of the previous filament that gets left in the hot end during a change. 00:14:17.240 --> 00:14:22.280 This is as simple as ticking this checkbox after enabling developer mode in the preferences. 00:14:22.280 --> 00:14:26.520 But wait, there's more. Teaching Tech has a really good guide on reducing purge. 00:14:26.640 --> 00:14:32.200 We're going to have that link down below. But in a nutshell, we're going to be enabling purge into infill, which is exactly what it 00:14:32.200 --> 00:14:36.120 sounds like. And we're also going to be reducing our flushing multiplier. 00:14:36.120 --> 00:14:42.320 This is the big one. See, you might care about the absolute purity of your colors. 00:14:42.320 --> 00:14:47.400 I don't. I'd be fine with, you know, red-ish. 00:14:47.400 --> 00:14:52.240 So what we're going to do is instead of purging this much flipping filament every time we 00:14:52.240 --> 00:14:57.280 change a color, we're going to set it to 0.5. That'll cut our waste more or less than half. 00:14:57.280 --> 00:15:00.640 So you're going to remember how to do all that stuff, right? Yeah. 00:15:00.640 --> 00:15:05.800 Okay, cool. Because if you minimize your waste, you minimize how much you pay me for filament. 00:15:05.800 --> 00:15:14.280 With that out of the way, I think we're pretty well optimized. The mechanical room is clean, and this is a way more comfortable workspace, especially 00:15:14.280 --> 00:15:21.200 if you need access to all the printers. To be clear, there is a lot more that we could do in the future. 00:15:21.200 --> 00:15:24.640 I could maybe move my badmints and stuff, and we could have like a queuing system for 00:15:24.640 --> 00:15:31.240 a filament that's pending drying. We could maybe get some containers instead of using those inconvenient vacuum bags and 00:15:31.240 --> 00:15:35.120 automating print removal. That would be incredible. Do you know you can do that? 00:15:35.120 --> 00:15:40.400 I didn't know that. You can automatically have the print get pulled off the bed, and then you can have it start 00:15:40.400 --> 00:15:44.080 another one for like mass production. Super cool. 00:15:44.080 --> 00:15:49.880 There's various options for that. AutoFarm 3D is an effective one, but is a subscription service. 00:15:49.880 --> 00:15:57.320 Octoprint's continuous printing plug-in is a great alternative. Work with Bamboo Lab, which is part of the reason that we stopped using these at the 00:15:57.320 --> 00:16:02.040 office. Once you figure out like which hotends you like, we could potentially explore getting 00:16:02.040 --> 00:16:10.960 some different hotends for the carbons as well. So like higher flow, or harder nozzles to enable more materials, all that kind of stuff. 00:16:10.960 --> 00:16:17.000 That's cool. Yeah, don't sound too grateful. 00:16:17.000 --> 00:16:21.040 Just like I'm not going to sound too grateful to our sponsor. 00:16:21.040 --> 00:16:25.080 If you guys enjoyed this video, why not check out the one where I showed off my 3D printing 00:16:25.080 --> 00:16:30.080 setup? Mine kind of sucked, but we collaborated with some other really incredible creators who 00:16:30.080 --> 00:16:31.720 showed off their setups that are a lot better.
