1 00:00:00,000 --> 00:00:05,840 You know what? You need more head. How about five? The new Prusa XL. We've just got this in, 2 00:00:05,840 --> 00:00:11,200 and I've been really excited about this for a long time. So this is the semi-assembled, 3 00:00:11,200 --> 00:00:14,720 so I'm probably going to rip all the parts out and then disappear for a little while. 4 00:00:14,720 --> 00:00:20,400 And we've got a rip tab. Oh, she ripped good. 5 00:00:20,400 --> 00:00:32,000 Always looks bigger in person, doesn't it? First thing I notice immediately is the size 6 00:00:32,000 --> 00:00:37,440 of the gummy bear bag has increased a lot. The instructions tell you when to eat how many. 7 00:00:38,240 --> 00:00:44,880 It's actually great. Looks like we've got some filament already, which is nice. The galaxy black. 8 00:00:44,880 --> 00:00:48,560 Oh yeah, that's right. We get a little receipt for all the pre-flight checks that they've done for 9 00:00:49,120 --> 00:00:53,840 and has a full LCD control panel, just like the Mark IVs and all of the other ones. There's our 10 00:00:53,840 --> 00:00:59,280 multi-tool extruder. Let's have a look at that. Oh yeah. Oh yeah, this is exciting. So there's going 11 00:00:59,280 --> 00:01:07,520 to be five of these. So here is the next struder with the automatic tool changing system on it. 12 00:01:08,080 --> 00:01:12,640 Oh yeah. Oh yeah, that's going to be great. Now this model does come in a few different varieties 13 00:01:12,640 --> 00:01:17,840 from like one head to up to five. It's a really good way to do multi-material, especially if 14 00:01:17,840 --> 00:01:22,160 you're going to be changing colors. So you can do multiple colors or you can do multiple types 15 00:01:22,160 --> 00:01:26,160 of filament. Looks like they've also sent us a nice little care package. I don't think this is 16 00:01:26,160 --> 00:01:32,160 standard. We have a second heated bed. This is the XL PEI spring shield and the sheet, 17 00:01:33,120 --> 00:01:37,680 which is really nice. And then a whole bunch of filament. Oh my god. Yeah, we've got some prusa 18 00:01:37,680 --> 00:01:43,120 filament. Look at all of this. Okay, all right. Maybe we'll be doing multi-color prints today. 19 00:01:43,120 --> 00:01:47,280 Oh, it looks like they've sent us some spare nozzles. That's pretty cool. These are hardened, 20 00:01:47,280 --> 00:01:51,680 which means we can print things like carbon fiber impregnated nylon and stuff like that. 21 00:01:51,680 --> 00:01:56,160 And these are part of the next struder system, which means that changing these out is pretty 22 00:01:56,160 --> 00:02:02,400 simple. My understanding is that we can't mix nozzle diameters. So these are all 0.4 millimeter. 23 00:02:02,400 --> 00:02:07,440 This model comes with both Ethernet and Wi-Fi capabilities. It shares a lot of similarities 24 00:02:07,440 --> 00:02:13,520 between the Mark IV, but they have the new segmented bed. So the Mark IV has one giant bed, 25 00:02:13,520 --> 00:02:18,560 whereas this one has what looks like 16 individual segments. And each of these can heat up 26 00:02:19,360 --> 00:02:23,520 individually, which means that you're not heating up an entire bed if you're only going to be 27 00:02:23,520 --> 00:02:27,520 printing right on the front or right in the center, which is kind of cool. Of course, you know, 28 00:02:27,520 --> 00:02:34,880 giant build area. So this one is 14 inches by 14 inches by 14 inches, which is absolutely massive, 29 00:02:34,880 --> 00:02:40,400 which is really cool to see. And this is spring steel and magnetic. So it just kind of sits in 30 00:02:40,400 --> 00:02:45,360 with a couple of little locating pins at the back and then snaps down, which is great. Let's get 31 00:02:45,360 --> 00:02:53,200 this out. It looks like we have linear rails for each of the motion systems. Compared to something 32 00:02:53,200 --> 00:02:58,640 like the Mark IV, which has one motor that controls the x-axis, this has two which work in tandem to 33 00:02:58,640 --> 00:03:03,280 control both the x and the y. Just like the Mark IV, each of these extruder assemblies have a load 34 00:03:03,280 --> 00:03:08,480 cell built in, which means that we can home and calibrate and do everything that we need directly 35 00:03:08,560 --> 00:03:11,600 through the nozzle. All of these are direct drive extruders. So there's a little stepper 36 00:03:11,600 --> 00:03:15,040 motor in here, which will pull the filament through. We've got channels on the side here 37 00:03:15,040 --> 00:03:20,080 with filament runout. So this will pop into the carriage here. And then these two locking tabs 38 00:03:20,080 --> 00:03:25,120 head over and click in. And then that holds the whole extruder assembly. So we'll have five of 39 00:03:25,120 --> 00:03:31,360 them at the back here. And then the whole head assembly here will come there and then release 40 00:03:31,360 --> 00:03:37,440 them and undock them and then move away and pick up the next one. Really, really neat system. Very 41 00:03:37,440 --> 00:03:41,680 excited. Looks like we're going to have to install the LCD and control panel ourselves. That's going 42 00:03:41,680 --> 00:03:46,640 to go right about there. And it looks pretty much identical to the Mark IV. Both printers seem to 43 00:03:46,640 --> 00:03:50,320 share a lot of similarities, which is kind of nice. I believe this one does have chamber 44 00:03:50,320 --> 00:03:55,600 illumination, but I think that's mostly some of the differences. Looks like our X-Y plate here 45 00:03:55,600 --> 00:04:00,080 is a giant block of milled aluminum, which is awesome to see. And then of course, yeah, the 46 00:04:00,080 --> 00:04:05,840 linear rails are also great. Still got some traditional 3D printed parts like these top 47 00:04:05,840 --> 00:04:10,800 Z-axis supports and things like that. But most of it seems to be really quite high quality aluminum 48 00:04:10,800 --> 00:04:15,760 parts. Looks like they've given us a test print in here, which is cool to see. Turning it around to 49 00:04:15,760 --> 00:04:21,360 have a look at the back. I believe these have three separate power supplies. You're going to have 50 00:04:21,360 --> 00:04:24,880 five heaters plus the entire bed. You're going to need quite a bit of power. Looks like we've got 51 00:04:24,880 --> 00:04:29,120 our standard aluminum extrusion channels, which kind of make up most of the frame. And it's got some 52 00:04:29,120 --> 00:04:33,440 nice blanking plates in here, kind of like your original Creality or something like that. And 53 00:04:33,440 --> 00:04:39,360 here's one of the mounts for the extruders. They're going to sort of sit back here and that'll feed 54 00:04:39,360 --> 00:04:46,080 your power and your data and all of your filament through there. It's got these two locating pins 55 00:04:46,080 --> 00:04:52,400 on the back. So this slot's in here like that. And it looks like we've got some incredibly powerful 56 00:04:52,400 --> 00:04:58,400 magnets that kind of keep it located. It's really important that these are in the same position 57 00:04:58,400 --> 00:05:02,400 every single time. We have a single cable, which connects to the hot end, is probably just going 58 00:05:02,560 --> 00:05:06,000 to fall down here and plug into the control box, which looks like it's right here. 59 00:05:06,560 --> 00:05:11,040 On this side of the control box, we have our Ethernet jack and there's also a USB-C port, 60 00:05:11,040 --> 00:05:14,400 even though I'm not quite sure what that's for yet. I'm going to flip it on its back and 61 00:05:14,400 --> 00:05:19,840 well, let's have a look at what the bottom entails. We've got our Z-Drive motors here and then 62 00:05:20,720 --> 00:05:25,920 nice big metal sheet at the bottom. Oh, look at all of those. You can see the individual cables, 63 00:05:25,920 --> 00:05:31,200 which go to every single of the 16 heating zones. Okay, here's a spool holder. Let's have a look at 64 00:05:31,200 --> 00:05:35,920 that. They're telescoping, so they kind of, I guess, just snap into each other. That's nice. 65 00:05:35,920 --> 00:05:40,960 Oh, they're going to go into these channels here. Easy. And they're adjustable because I've got some 66 00:05:40,960 --> 00:05:47,600 big spools. We print with some large spools because we do so much all the time here. We have quite a 67 00:05:47,600 --> 00:05:52,080 nice toolkit, it looks like. We've given us a full-size screwdriver, even though we probably 68 00:05:52,080 --> 00:05:57,840 won't be using that. That would be illegal. It was where I was a pair of pliers and some allen keys 69 00:05:57,840 --> 00:06:02,080 and wrenches, which we're going to need to do all this screwing. A little thumb drive here, which is 70 00:06:02,080 --> 00:06:07,200 great for firmware or printing, but you don't actually need that as this has Prusa Connect, 71 00:06:07,200 --> 00:06:12,560 everything built in, which allows you to manage multiple of these for a print farm if necessary. 72 00:06:12,560 --> 00:06:18,160 I think we have about eight or so mark fours now, which are all connected over Ethernet and 73 00:06:18,160 --> 00:06:22,480 controllable from one central location, which is great. I really like seeing Ethernet on printers 74 00:06:22,480 --> 00:06:25,840 because it's a little bit more reliable and a lot more faster. Although if you want, you can run 75 00:06:25,840 --> 00:06:31,200 this completely offline. Absolutely no cloud service necessary. They know who I'm talking about. 76 00:06:31,840 --> 00:06:36,480 Each of these nozzles need to be put in and then ran and then it has to go through all of its 77 00:06:36,480 --> 00:06:41,040 preflight checks. There's a hole right in the center where you put a little peg and then you're going 78 00:06:41,040 --> 00:06:46,560 to be moving each of these nozzles onto that to make sure that their z-height is known perfectly 79 00:06:46,560 --> 00:06:51,680 and then it'll kind of bump into all of the sides of them and so it knows its x and y coordinates 80 00:06:51,680 --> 00:06:55,520 and then it'll store all of those offsets internally and then you won't have to worry 81 00:06:55,520 --> 00:07:07,600 about that again. Now if you don't mind, I'd like to be alone with this thing for a little while. 82 00:07:10,960 --> 00:07:16,480 Hello, Future Dan here. I let a print run overnight. We did a nice multi-color Kirby. This little guy 83 00:07:16,480 --> 00:07:20,880 took about four and a half hours compared to some of the other little layer tests that I did. 84 00:07:20,880 --> 00:07:24,400 I want to try this one overnight as this one has interlayer nozzle changes compared to the 85 00:07:24,400 --> 00:07:28,800 little tests that I started out with which every layer was a different material. I also 86 00:07:28,800 --> 00:07:32,480 switched the bed type. This is the textured bed compared to the smooth one that we tried these 87 00:07:32,480 --> 00:07:37,760 tests on. You can see on both of them that it's left these long stringing things after it purges 88 00:07:37,760 --> 00:07:42,560 all the nozzles before it starts printing on both of them. Like I didn't clean up any of the mess 89 00:07:42,560 --> 00:07:46,800 that it left because I kind of wanted to see how that ended up and yeah it's a bit of a messy 90 00:07:46,800 --> 00:07:51,280 printer but I mean these are kind of easy to deal with. I normally keep a little waste basket 91 00:07:51,280 --> 00:07:55,920 next to my printers anyway but this one in particular is a bit snotty. All right let's see 92 00:07:55,920 --> 00:08:03,280 how it releases from the bed. Okay, just slides off instantly. That's kind of great. Somebody 93 00:08:03,280 --> 00:08:11,440 put a gummy bear in here. Whatever. And we have a new type of purge tower too which is kind of cool. 94 00:08:11,440 --> 00:08:15,600 Yeah, this is a five-color print. Looking at this it seems pretty good. There wasn't really any 95 00:08:15,600 --> 00:08:22,640 stringing or much at all between the purge tower and the part itself. Not also seeing too much of 96 00:08:22,640 --> 00:08:27,920 the z-height ringing. The Joel the 3d printing nerd based greatest goat of all time. Notice when 97 00:08:27,920 --> 00:08:33,280 in his review as well there's some slight overhang stuff there but that seems pretty okay. And other 98 00:08:33,280 --> 00:08:37,920 people are also noticing that there was some blobbing in between where you know a little bit 99 00:08:37,920 --> 00:08:41,920 of a different color would stay stuck to one of the nozzles. Maybe a little tiny bit in the eye 100 00:08:42,000 --> 00:08:47,200 there but I'm not noticing too much. It might just be a larger particular piece in 101 00:08:47,200 --> 00:08:53,200 Marvel PLA that they sent. It's pretty good. Mechanical strength between the two colors is 102 00:08:53,200 --> 00:08:59,600 also really good. And kind of nice thing was that I just colored this inside Prusa Slicer itself. 103 00:09:00,480 --> 00:09:06,000 So software works well for just filling a pre-existing singular model. Purge towers are 104 00:09:06,000 --> 00:09:11,120 kind of cool in this system. The time between layer changes is nearly instant. It just basically 105 00:09:11,120 --> 00:09:16,480 goes zoop zoop zoop and then continues which is really nice. This model printed in about four 106 00:09:16,480 --> 00:09:21,920 and a half hours and contained over fourteen thousand five hundred individual layer changes 107 00:09:21,920 --> 00:09:27,520 which is insane for that amount of time. And yeah on the inside you can kind of wow that's strong. 108 00:09:29,040 --> 00:09:32,960 On the inside you can kind of see how it builds out those interesting little layer lines. There's 109 00:09:32,960 --> 00:09:39,040 not too much in here. It's mostly empty. Depending on the severity of the layer changer or how many 110 00:09:39,040 --> 00:09:44,160 are in one layer it'll do you know a couple of lines and it'll do a little bit of a drag and 111 00:09:44,160 --> 00:09:48,080 then go back and change its tool head. It's really neat. This is kind of exactly the level of 112 00:09:48,080 --> 00:09:53,600 performance that I would expect from Prusa. The build quality is excellent. The printing performance 113 00:09:53,600 --> 00:10:00,480 is excellent and the instructions were also excellent. I wasn't expecting it to be this 114 00:10:00,480 --> 00:10:05,600 kind of simple to put together. This is the fully assembled one where basically all I had to do 115 00:10:05,600 --> 00:10:09,840 was just attach the hot ends and that went together really nicely. The full calibration 116 00:10:09,840 --> 00:10:16,000 included in the software is easy to follow and very simple. It fits our giant spools of you 117 00:10:16,000 --> 00:10:20,160 know two and a half kilograms of PLA which is great. I think some of the issue comes down to 118 00:10:20,160 --> 00:10:25,680 maybe price and who is going to be buying something like this. I know definitely we're going to be 119 00:10:25,680 --> 00:10:30,480 using it here. We don't have a printer with this size build volume and certainly not something 120 00:10:30,480 --> 00:10:36,000 that's easy to use. It'll fit right into the rest of our Prusa ecosystem with their little 121 00:10:36,000 --> 00:10:40,880 Ethernet and wi-fi connected thing but I mean they'll even allow you to break little piece 122 00:10:40,880 --> 00:10:45,760 on the circuit board and load unsigned firmware too if you wanted to go a bit further with it. 123 00:10:45,760 --> 00:10:49,920 I know there's some complaints about camera compatibility but that's not really something 124 00:10:49,920 --> 00:10:55,600 we care too much or value here. This printer here would be the most expensive offering they do which 125 00:10:55,600 --> 00:11:01,600 is the fully assembled and the five head system which comes it to four thousand US dollars which 126 00:11:01,600 --> 00:11:07,280 is a pretty hefty price to pay for something like this. There are other offerings that are cheaper 127 00:11:07,280 --> 00:11:13,120 that will do multi-material. The price category and the kind of competence of this would be for 128 00:11:13,120 --> 00:11:20,800 somebody who wants prints to happen constantly without worry you can just kind of you'll know 129 00:11:20,800 --> 00:11:25,520 that it's mostly going to work ninety percent of the time because you have five nozzles compared 130 00:11:25,520 --> 00:11:31,520 to a single nozzle or even another multi nozzle which has to purge the nozzle every single time 131 00:11:31,520 --> 00:11:36,080 that it does a color change pull the filament back cut it you know do whatever like that 132 00:11:36,080 --> 00:11:41,760 all of these are just ready to go and so the layer times for doing this little wipe tower are 133 00:11:41,760 --> 00:11:47,120 really quick. When I'm prototyping stuff for here I'll do multiple revisions on a nice fast printer 134 00:11:47,200 --> 00:11:53,360 and then I'll batch print them on our Prusas because they're reliable and they're dimensionally 135 00:11:53,360 --> 00:11:58,320 accurate and we just know they work you just set it and then leave. Maybe I'm going to be doing 136 00:11:58,320 --> 00:12:04,480 five or six different types of materials on one plate maybe I want to test a prototype in five 137 00:12:04,480 --> 00:12:08,640 different materials simultaneously that's that's kind of your option I think this would probably 138 00:12:08,640 --> 00:12:13,920 be a lot better for multi-material rather than multi-color if you want to think about it that 139 00:12:13,920 --> 00:12:18,640 way. I think at the opposite end of the spectrum the one head semi-assembled variety which may be 140 00:12:18,640 --> 00:12:23,280 more like a home user or a hobbyist or something like that who has time to spare which is two 141 00:12:23,280 --> 00:12:29,600 thousand US dollars is probably going to be the best entry point into a build volume of this size. 142 00:12:29,600 --> 00:12:34,880 Now that's about twice the price of an entry level mark four but you get a hell of a lot more build 143 00:12:34,880 --> 00:12:41,440 volume. I was doing some parts recently and I needed to do a giant motherboard tray and I had 144 00:12:41,440 --> 00:12:45,440 to segment that into five or six different pieces instead of just being able to print it on something 145 00:12:45,440 --> 00:12:50,400 like this which is great so having a massive build volume can be useful. You can buy both of the 146 00:12:50,400 --> 00:12:55,840 expansion boards that are included in this model including the extra hot end one and the wi-fi card 147 00:12:55,840 --> 00:13:00,800 that kind of just slot in like PCR cards are kind of neat. I'm also happy to see that they're including 148 00:13:00,800 --> 00:13:05,040 each of the individual little bed tiles because I maybe want to buy those for another project that 149 00:13:05,040 --> 00:13:10,240 I'm working on. As a reminder this kind of isn't a review this is just first impressions and unboxing 150 00:13:10,240 --> 00:13:15,680 so I think this printer warrants maybe a little bit more research. I am very happy with this though 151 00:13:15,680 --> 00:13:20,240 I think this is going to meet our needs perfectly because we're distributed around the buildings 152 00:13:20,240 --> 00:13:25,680 having this printer web connected with five filaments loaded is really useful because somebody from 153 00:13:25,680 --> 00:13:30,720 any building can connect into this and then just pick a filament that's loaded into it and print 154 00:13:30,720 --> 00:13:35,440 the effectively that way. The lack of built-in camera though does make it difficult to start a 155 00:13:35,440 --> 00:13:39,680 print to make sure that there's not already a part still waiting there like this was sitting 156 00:13:39,680 --> 00:13:43,680 overnight and then I come in in the morning and start another one and then just destroy it. 157 00:13:43,680 --> 00:13:48,320 I don't know I think you did a great job. Good job Prusa. You make you make good things. If you 158 00:13:48,320 --> 00:13:51,680 like this why don't you check out the video that we did on the Prusa mark four. We have loads of 159 00:13:51,680 --> 00:13:59,200 those and we love them. We love them. We love the Prusa. My precious Prusa.
