The Prusa XL Review!

[@thejosefprusa]

Hi Joel, it gave me a little heart attack when I found out you are getting the show printer back then 😅 I have a few notes and tips 💡⤵ - For the correct generation of the organic supports on multipart objects, you just merge them (select objects > right click > merge). It cannot be done automatically because of some edge cases for now, but we are getting there. - IF you are big into multi-material painting of objects, get a cheap pen tablet (like Wacom One S, but any will do), and it will change your life. - I also want to point out the Smart Fill feature, which automatically detects edges when you paint a model. - I love how you are not shying away from the very complex things like mixing together tool changing and filament swapping! We'll fix that M600 tool selections asap, good catch. Do you have any more of these “integration hell” use cases in the pipeline? - Most people just keep forgetting that XL is not just the 5 head toolchanger, there is 2 head variant for $2500 which you can always upgrade later on. It's the perfect choice for 95% of engineering purposes, with the single tool coming in even cheaper. - As for the tip what to try out, it would be incredible to see your take on some tool. Imagine 3DPN Screwdriver with a core printed from PCCF so the bit can be held securely and flex over molding for the nice cushy handle 🤔 I am super happy you are enjoying the XL and cannot wait for your multimaterial adventures! 🫶

So has the "layer shift" issue been fixed (tool heads, on change, do not always sit 100% the same every time, and require a "bump" or tuning/tightening) on new units shipping out? its still a very expensive machine to not work 100% "out of the box" :(

[@chicoriver8606]

Happy printing 👋

[@williambrown1094]

When are toolheads for upgrading 1 or 2 tool variants going to be available?

[@Phreakrider]

Ship it with bigger gummy bears! The 5 pound tri-color gummy bear would be perfect!

[@TheMikolasZuza]

@@marcusone1 as the video explains, the layer shift is fixed by lubricating the pins, it takes 30 seconds to do and makes all the difference! We have meassured the before and after here. It is not possible to lubricate them here, it needs to be done after the toolheads are attached and typically it only needs lubrication after the machine did some hours of printing.

[@Bretto311]

I could get on board with the price tag, IF this printer worked reliably and flawlessly. I have had my 5 tool now for a few weeks and still fighting major noise and vibration issues when the tool head travels along the y axis in the middle of the build plate, major stringing issues, I had tool head crashing issues(which I think I fixed), firmware errors, this was a factory assembly printer and I’ve reached out to prusa support 4 different times now, still no solution and the last time I reached out they said they would get back to me and never did. I was a prusa fanboy, but after waiting 2 years and having lots of issues,this has changed. I hope someone comes along and makes a large multitool that just works, I’d still pay 4k for one, just not for this one.

[@Shadowstep1321]

Totally agreed with you, got a 2T factory built back in Aug. was working okay for a time, but then a linear rail started to fail on the z-axis. It's taken Prusa 4 MONTHS to get it back to me in working order, and now they forgot to send me back the calibration pin, so it gets to sit a few more weeks while they decide to ship me a new one, which they still haven't confirmed. So much frustration over what is a lot of raw potential.

[@mrkthmn]

I'm in such a similar boat!!! I was a fanboy after having an amazing experience with my MK3 but the MK4 I bought new from them is a lemon and Prusa Support just keeps brushing me off telling me stuff like, "oh that isnt an issue" regarding the head twisting filament so rapidly & badly that it knots up after about 20 minutes. I would say thats very much an issue!! (and yes I've rebuilt it, reprinted the parts, adjusted everything 20 times, etc...). Another issue is that all of my prints warp to failure no matter what settings, plate, filament, etc. In response they recommended me an article about print temps/warping. I know how to print!! Not only have I run the gamut from below all the way above the recommended range for both the filment and the bed, I've printed the same model with the same filament at normal temps just fine on my MK3 so why am i even having to do that?!?! At the end of the day I have done hours(!) of my own research and trouble shooting, reprinted loads of the printers parts (using my MK3), and done all the tedious things they have asked me to do like send them a bunch of pictures (every chat) of the printer and failed/warped prints just so they can say, "Printer looks good, read some articles, on you go!" I shouldn't have to recite a dark incantation and scribe runes on my fancy new printer to get it to effing work. Its been infuriating and completely burned me on the brand. At this point it just makes me even more mad when people actually get working machines and rave about how good they are. Must be nice. 😤

[@alksmdlaks]

prusa is honestly just getting by because of the name these days. it's like Apple, their fanbase is convinced that they are the best because they were at one time, but the competition is way cheaper and better in most ways now.

[@vy1w1yv]

@@alksmdlaks Yes, the "quality" that you are privileged to pay for and, yes, wait a long time for, will arrive 80% ready. But you must think of it this way: "You have the bleeding edge of what technology has to offer; so, you should not expect it to be error free." This is the same Jedi mind trick that Ferrari and now Tessla pulled ; )

[@karmakh]

Multi material is the primary reason why I decided to get XL 2T. Not trivial to use, but it's been great overall. Worth the price, IMO. PETG-PLA support mix (either way) is awesone, not to mention mixing in TPU with harder plastics for true multi material prints.

Great review, thanks for hitting some the key points alot of people seem to miss, which is there really is no other machine out there like this.

Wow... you went DEEP! And I love it. So glad you took the time to run the machine through its paces. Also, amazing that you're already pushing the envelope by shining a light on the support generation limitations and the M600 color change options.

[@johnbrooks7350]

I would disagree regarding it having an “early adopter” tax. You could say that about the E3D toolchanger. Even for the E3D TC, it still was using mostly old tech from industrial 3D printers or CNCs. Prusa really is stretching how much they should charge for this and it shows with their pro line of printers getting closer in price. I think the Prusa XL is an incredibly interesting printer but they’re trying to charge a Pro price when this is still a hobbiest machine with its limitations.

[@GuyH77]

Good overview and agree the XL has huge potential still to be unlocked. One weakness is the tool mount fixing at the back. A single screw in a captive part in the back extrusion. If these aren't tight then the tool dock won't remain in an ideal position. This can contribute to the uneven layers you have/had. I hope they improve this part of the design. Some threadlock and ensuring the mounts are correctly aligned as well as tight will help. I'm loving my XL, the ability to reliably print large parts as well as full beds of parts make it worth the money to me.

[@woodwaker1]

I had the same problem / concern. I had to return my x y carriage to Prusa, The number one hole was stripped. They need to make this at least a two position mounting system, three would be even better, tow bolts and a alignment pin.

[@Cone_GamingYT]

@@woodwaker1 I think since peo0le have complained they have fixed it

[@GuyH77]

[@Cone_GamingYT]

@@GuyH77 I mean prusa isn’t bad as anything but I would think they have fixed it. Also, I am buying one my slef but I don’t know what to get. The 2 tool head or the 5. And will there be upgrades to add tool heads to the 1 and 2 ones?

[@GuyH77]

@@Cone_GamingYT If you can afford it then get the 5 head. Lots of people on the forums with 2 wishing they had more, not necessarily 5 but currently that's the choice. Prusa will offer tool upgrades in future but they're still working through the backlog so not sure when that is. Also, the 5 tools need an extra board and PSU. They've not improved the tool dock fixing and it is an area that can be improved. The docks can work loose over time. Then you're scared to strip the insert as replacing it involves disassembling the printer....

[@ulforcemegamon3094]

I think one thing that it should have is that the slicer should be compatible with different nozzle sizes in the same model , that way you could have multicolor prints with really nice details , and in my opinion that would make the machine as a whole better

[@krollmond7544]

That and if it came with an enclosure I'd consider it one of the best on the market.

[@ygk3d]

Great video Joel! Thanks for featuring my solution for the layer banding issue. I'll definitely be trying the lubrication method to see if that helps instead.

[@grantdeisig1360]

I'm surprised you haven't done an update video yet about that situation. My 5 head doesn't seem to have this issue...? And I haven't had to lube mine either. So now I'm curious why yours is doing that. I'm very maticulous when I set the docks and calibrated them, so my stuff seems to be spot on. Have you tried checking the mounts and recalibrating the docks again?

[@ArdjanVideo]

I have my XL/5 since mid-november. And I can confirm the findings of Joe. I did not yet lube those screws, but will do it soon, since I now understood why. (That's the downside of a semi-assembled vs a full kit like my MK3: for that machine, I knew every screw...) What's also a big plus: cleaning of the nozzles. I started to do once a week a cleaning: place a protection on the build sheet, pull out a toolhead manually and lay it on the sheet, let it heat up to 230° or so and use a brass brush to clean the nozzle. All easy reachable and fast cleaned.

[@TheMikolasZuza]

Awesome review! I can't wait to see what people will do with the XL. PETG with FLEXible soft touch handles, print in place rubber seals, PLA with PETG supports! Woodfiil with PETG-CF for amazing aesthetics! So many possibilites. :)

[@swashbuckle3713]

Finally a KZbin reviewer that read the manual and adjusted the nozzle seals correctly. This pretty much matches my own experience with the 5-XL. Fantastic machine that's currently in a league of its own when it comes to multi-material printing.

[@grantdeisig1360]

I'd have to look it up and check them. But I got the fully assembled version, so I didn't touch the seals during my assembly. Should I have? They seem to be working just fine, but they are pressed down when seated against the nozzle.

[@fribbledom5256]

@@grantdeisig1360 Yes, I'd check them. Having them properly adjusted makes a huge difference, as hot nozzles will otherwise ooze filament when parked. Even the fully assembled version requires you to attach the individual toolheads to the frame, at which point you should check the seal is parallel to the nozzle you're using. It's just a few turns with a screwdriver and only takes a minute, really.

I was nervous to complete my preorder, but I'm glad I did, my XL is performing darn near perfect. I haven't had to lube my 3 contact points at all and I never have alignment issues. Being able to print with different materials is so much fun. (Albeit, a whole new learning experience as well.) I did, mix and match nozzles for the time being. Would be nice to see some nextruder nozzles offered from diamondback or maybe some tungsten carbide nozzles in the nextruder so we don't need an adapter. I did notice that on bigger prints putting out a lot of filament, that the overture spool wore a grove into my spool holder. Not a big deal but the abrasive nature of the cardboard is a little harsh on the spool at higher speeds. But all in all... I'm 95% satisfied.

[@scottrini6889]

Been waiting for this! I got my preorder in on the first day as well and been printing with it since August! I had some issues at first, but I've been loving it since

[@rcmaniac25]

Well covered review. There is so much to cover on what to do in a printer, especially at this price point. Let me get the weird/annoying stuff out of the way first... An example of a complaint I've seen: "For that price, it should have a camera!" like the rolling shutter one on the Bambu X1C? Or the 1FPS one on the P1 and A1 series? What if I don't like the camera angle? What if the lighting doesn't look good? Do you now go "good thing this came with a camera, I'm going to ignore it outside of checking print progress and setup a better camera and print that riser so I can put a light bar in there"? I own a single tool XL, a "semi-assembled" model, which I've had for around 6 months now. I chose 1 tool because 99% of what I print is 1 color and I planned to do multi-color and multi-material another time. But it had an interesting side effect: most of the complaints people had on the XL, I didn't have. Did it string? Yes. Did it string like it didn't know how to extrude plastic? No. Did it string as much as an out of the box X1C, P1S, A1, Ender 3 V3, the dozen of Vorons I've seen, etc.? Yes, yes it did. There's a lot of drama in the community right now, and having seen (and probably contributed to) it, I think it's come down to a very fine line that is person dependent: when is it pointing out an issue/desiring improvement and when is it vitriol/fanboyism/hate? I want people to print cool things, but I also want prior people's work to be respected and for credit to be given where it comes from... I see a lot of "well they innovated this" and it's become very Apple vs. Android where you can point to something that occurred in one of them, sometimes years before the other got it, and then people viciously defend the brand they own/chose when called out for claiming they created it when it's demonstrated they didn't. I think it's also a lot of human factor: people don't want to be told they made the wrong choice, and they don't want to hear their choice isn't perfect. How many hours did you work to make the money to purchase something? How would you feel if you couldn't get those hours of life back but you purchased V1 and a week later V2 came out? I think that handwavy topic that could be much deeper, needs to be mentioned. The Prusa XL is not perfect. I am happy with my purchase and it works well and for what I wanted it for. But as an owner, I'm going to be critical of it. One of the unique issues I had was that my heated bed had electro-magnetic interference that caused the tiles to error when preheating. I worked with Prusa Support for around 4 or 5 hours, they asked me to check every wire for proper crimping (which I felt was not appropriate for something that had QR codes all over things for quality assurance, and that since Prusa has said publicly "this is not for consumers", a prosumer or business owner is gonna balk at that amount of time to check something like wire crimping). In the end, they said "we unfortunately need to report this to engineering and will have to get back to you". 2 weeks past, with me pestering every couple days for a status update. Eventually they came back, they apologized, they offered to send me a spool of filament in addition to the fix (my mind was blown when they offered marble prusament instead of galaxy black). I had to contact them 2 more times before they actually shipped it. But in the end, I got a metal plate... and I installed the metal plate between the electrical contacts and the heat bed... and my issue went away. It blew my mind that via some text and a set of pre-heating tests, it was determined the issue was EM. But here we were. I told people about this, and had plenty of people say "this printer is a failure. It shouldn't have been sold. It's DoA" etc. And I met one at ERRF 2023 who went "wait... what do you mean it's working?" "support figured out a fix and sent me the parts and instructions. I installed it and it's now working" their face said "no way, they got it to work?" I complained, I told people of it's problems, and the most important aspect of it all: I contacted support. When it made little bumps on the heatbed, I contacted support. When it made noise I didn't like, I contacted support. I contacted support on average of 4 times a week for a month for every little thing... and I had the cheapest $1500 version. I didn't have it out for Prusa, I didn't throw it in the trash and make 5 dozen Tweets saying how disappointed I was as if I already had made up my mind on the printer. I said "hey, this isn't working... please help" and they did. I think Prusa stumbled, I think shipping needs work. I think the firmware could use improvement... I literally used the touch screen on a Prusa User Group event and it worked fine... why is it still not out? I made Github tickets for the First Run setup, on cancel object, and more. I have even more tickets for PrusaSlicer and think it can be improved greatly. I want the team to stop dancing around the request and actually do multi-bed support (they stated they are working on it, but for the longest time they said no, no, no, it already exists, we can't because we don't know it's origin, we can't do it. People people didn't take that as an answer and they're working on it now). I'm hoping when they start selling extra tools, I can do different size extruders with different materials and M600 swaps and more... and have it just work. And just like how people had tons of issues with the MK3 when it came out... they eventually got fixed and it became the nearly unstoppable printer. There are still people buying MK3s... and advised someone if they're gonna get a Prusa, get the MK4... they said "meh, the MK3 is cheaper". And even when pointed out there are other brands with the feature sets... they said they were getting a Prusa. They weren't naive or stupid... they had a set of requirements and the MK3 met them. So when we have issues, we can let them fester in our mind. Speaking them only to close friends... or we can let them know in support, with tickets, or calling them out online to draw attention to it. I'm going to keep glaring at the enclosure not being around, hope they put a camera on it, release some way to do input shapping (if anything, to quiet those that believe it can't be done from a factory... contrary to what some names in Voron/Klipper community have said), and keep contacting support and making requests. And you should do the same for your Bambu, either for a bigger one or for better security and not overlogging (which is a real thing, stop pretending it's made up), or Creality, or any machine. So I'm glad Joel that you have had great success and greatly enjoyed the XL. I would love to see if the out of the box experience for the review unit is better, worse, or the same. If you don't lube the pins, does the review unit have some of the same issues? I hope that painting improves (smart fill only goes so far), M600 improves, and more because software is easy to fix... just give it a couple weeks for larger stuff, but smaller things can be done in hours or days. I look forward to seeing what comes next, because the closest I've seen to a tool changer like this is nearly the same cost, but is built from scratch and doesn't come with support or warranty. Hopefully it gets faster, some sound dampening is applied (printing is quiet, travel moves... not so much), and more come. I'm sure it will, and with new machines, we'll see what people do. I also would love to figure out the intersection line of how much waste needs to be created before a tool changer becomes more effective then a single tool. Also... MMU on XL? Hint hint, nudge nudge Prusa... 25 color options... purchased as needed/desired... no, I'll let someone else figure out how to setup 25 spools for something like that...

[@mrfoameruk]

A lot of money and well out of the way of home users. Even at £1300 the X1C is expensive but the P1S with AMS for £800 is a good deal. The Prusa looks a nice machine but I worry about the price and its not even enclosed and the filament is out where it can hydrate or get dust on it. It has some great plus points but seems to be lacking in some essentials as well. I think its time to go back to the drawing board. Also, the Bambus can do 16 colours for less money.

I have a Bambu P1P with an AMS, and I don’t think 1 extra color/material and an extra 100mm in length, height, and width is worth 4x what I paid. Someone who has a printing business might disagree with me, and that’s totally fine.

I really enjoy mine, got a set of 0.4 nozzles I'm going to switch to for increased detail. Would love to be able to have 0.25 on two of them and have the slicer be able to use them in one print for small features in a print. Also worth to highlight is the fact that switching between heads and priming is so fast compared to the MMU or AMS!

[@grantdeisig1360]

I'm hoping that the next version of Prusa Slicer will give us the ability to mix nozzles within a single STL. I thought it did, because the options are available in 2.7.1, however, someone pointed out to me that it doesn't work and gives an "invalid" text where "slice" would normally be, and I tested it and they were correct. So figures 🤞 for the next iteration.

[@ulforcemegamon3094]

Yeah , multi-head will always be faster than a single nozzle doing color changes , also it barely produces any waste , which is a big plus

[@mattparkmakes]

I would like to see you do future videos that explore functional multi-material prints, strategies for multi-material supports, and tradeoffs and benefits for when to use 0.4mm nozzles or 0.6mm. I ordered an XL for large prints, so understanding speed versus quality is important to me.

Glad you're having luck with the XL. Got my 2 head XL early Dec 23 and it hasn't printed anything yet. Yes, I'm working with Prusa and have the current firmware. Have not been able to even do a test print. So far I can't get it to calibrate the filament sensors on both heads, then when calibrating the nozzle alignment it says BOTH nozzles "Don't seem to have a round cross section". These are brand new, never used , out of the box. Then it suddenly pops a big message saying MODULAR BED ERROR Unexpected invalid current. This is new, never used. It came with a test strip saying this machine was tested before shipping. Was it? I don't know. I probably should have waited on the purchase till they get the bugs out and get the software fixed. My almost 5 year old MK3 is a champ and works anytime I need it. Hopefully Prusa can fix this. I'm almost ready to send it back.

[@Toy_and_Prop_Masters]

Hi Joel, excellent video! Sorry for the lengthy comment in advance. I was initially leaning toward the Prusa XL, thinking it would finally meet my needs, but after watching your video, I’m now unsure about whether it’s the right choice for my specific requirements. To give you some context, what I primarily need from a 3D printer isn’t necessarily speed, but precision. I often prototype intricate parts that must fit together with tight tolerances, so accuracy is key. I was initially drawn to the Prusa XL for its build volume, which I thought would be ideal, as my typical print heights range from 2” (50mm) to a maximum of 14” (356mm). While I mostly work with single-color prints, I’m also open to multi-color or multi-material options when needed, like the XL promises. However, the most critical aspect for me is achieving a smooth surface finish akin to SLA prints, but without the associated hassle of maintaining an SLA printer. I’ve heard that the Prusa XL’s slicer now includes the Arachne perimeter generator, which promises improved print quality, and that was something I found promising. Based on your extensive experience with various machines, I’d love to hear your thoughts on which printer would best meet these needs. Specifically, I’m looking for precision, ease of use, and the ability to deliver professional quality prototypes, without the maintenance demands of an SLA system. I trust your judgment and would greatly appreciate any suggestions or guidance on what to consider next in my search. Should I keep waiting or should I take the plunge? Thanks again for all the valuable content you create, it’s been a huge help!

Great review, and looking forward to more exciting XL hijinx!

[@JeffreyHawkins]

When you get the review unit, please include comparison of the XL basic (one color) print quality with it's 0.4mm nozzle to something like the MK4. Existing reviews based on the 0.6mm nozzle and earlier software showed issues. I am interested in knowing if the nozzle change and other tweaks have improved things.

[@jenshendriks9092]

I forgot which youtuber said this, but I agree that Prusa has not done anything to keep their spot as one of the most popular printer brands. They just gave it away to Bambu Labs. They just make already existing printers for a higher price and the XL is something their consumerbase didn't ever ask for.

[@emberprototypes]

I like and appreciate how honest this review is, thanks Joel!

[@MaheerKibria]

So I agree when something is a class of its own you can charge whatever you want. I also agree that if competition happens the price will go down. What I am thinking is whether it is possible to upgrade a base XL with additional tool heads later?

[@ShotGunner5609]

Yes, just costs more.

[@MaheerKibria]

@ShotGunner5609 I'm more concerned about how much time it takes to add the additional tool heads. Like, is an easy end user upgrade, or is it really involved.

[@Zachary3DPrints]

Great and honest review about the Prusa XL. I said at SMRRF to Rudolf that I really would like the borrow a XL for a while, since I don't have any budget soon for a XL... He was laughing about is, he said that this was an very original request that he didn't heard before...

[@SneakyJoeRu]

The price is fine. 2 headed model will be useful for most people who don't need multicolor just for the sake of support material without purge. Superb investment if you have space and resources. But I barely found space for my X1C and I love the drybox ams, so I'll just stick with it. It does all I need and I also don't do many multicolor prints.

[@jeffstucky6010]

Great review! Patiently waiting for the email from Prusa for the order I placed a year ago :)

[@802Garage]

It's an impressive machine with a lot of potential, but it is very expensive. When you look at what the print heads cost vs an AMS, the price doesn't make total sense. Much as I want Prusa to succeed, I am hoping other companies can make machines like this for a lower price while fixing some of the key issues.

[@bridget_clinch]

Definitely go .2 layers with a .6 nozzle to get better overhangs. Maybe randomise seams and just tune linear advance well. I've finally got a bigger workspace now, so I'm still deciding what big corexy to build to go with my Anycubic Mega x, Prusa mini, and voron 0.1. Leaning towards a vzbot or voron trident still though.

[@jellybeanpowder]

That's a solid looking printer! Also, I love clockspring's stuff! Good things

[@stal1963]

I think, the Prusa XL currently has some issues which need to be solved. It’s a professional machine for (semi-)professional users. What I don’t understand is the fact that Prusa didn’t include a full enclosure for this price. For me the printer is too large, as it won’t fit in my appartment - yes, that is a problem some of us have. However, this printer should not be compared to Bambu Lab, but rather to industrial offers such as S7/S9 from Ultimaker or Raise Pro which easily cost double the price without toolheads or the build volume the XL provides. BTW: I own a Prusa Mini and a Bambu Lab X1C. Both printers make me happy for their quality and service, though I use the Mini not so often anymore.

[@reaper1304]

I love my MK3S+ and would love to get my hands on an XL but that price is just to much for me to justify. I know as you said this is the premium you pay as an early adopter and I fully agree. I wonder if in the future we might see a core XY option from Prusa which is scaled between the MK4 and XL build volume with 3-4 tool heads in the $1.5k-$3k price range.... Perhaps that's wishful thinking but its something I would 100% be interested in. Love your videos Joel, keep up the great work.

[@rudolfkrcmar]

Maybe 2 toolhead XL for $2500 could be an interesting option for you. It unlocks multi-material options and you can always upgrade later if you run out of toolheads.

[@sllimj1]

I have had my XL 5 head for a couple months now and have yet to have a priming tower stick to the bed, prints single just fine, wondering if you are having the same problems.

[@sllimj1]

Just an update, I did use Prusa multi-prints that come with the printer,

[@ScytheNoire]

Lots of people are having issues with multi-headed printing. The system just isn't working well due to the print heads not seating properly with the magnet system. There are a lot of videos outlining the issues with the XL. So far Prusa has been ignoring the issue, it appears.

[@FullEarthWorkshop]

Excellent video…your delivery looks just effortless! Love it!

[@Doogleraia]

That very same support issue in prusa slicer happens in creality print, it's almost like supports are reaching a point where someone needs to make them generate as a separate model that could even be saved as an stl. Would solve a lot of cross-slicer issues if one slicer could make better supports and you could just export it to another slicer that maybe does invisible seams, or maybe has better advance overhangs etc.

[@No0o0o0o0o0]

Take it's nearest competitor(P1S) and you need to purge about 3k worth of filament before you break even getting the XL. Considering the green and black company uses about .4 grams per color change(let's round to .5 for simplicity, and you can go lower) so 1000 grams per roll X .5 grams = 2000 color swaps to eat a 1kg filament roll $3000 / $20 per roll = 150 rolls 150 rolls * 2000 color swaps to eat a roll = 300,000 color swaps to break even in cost. I cant even imaging how many rolls you would need to print to make the XL worth that.

[@Leo-yh1lj]

Thanks for this review Joel. Me still on a 1 toolhead but really want to upgrade to more (hopefully to 5) when they will have those available in the near future. Changed my 0.6mm nozzle to 0.4 already for this one. Can't wait for the other fully 0.4mm nozzle 5-toolhead review/compare video.

[@Amarand]

I’d love to see a basic visual comparison between the Assembled and Semi-Assembled versions. I’m thinking I might want to save $500 and get the Semi-Assembled version? Is it a nightmare to put together? I’ve done the Field Engineer thing for a few decades (even worked on supercomputers back in the SGI/Cray days), so maybe it shouldn’t be an issue.

[@ch4.hayabusa]

Why not injection mold with a high temperature filament, or coating. Perhaps get conductive fillament and nickel plate it with water cooling channels below it.

[@reasonablebeing5392]

Good review. XL still has teething issues but I'm confident it will be optimized. It will take a "village" of users to perfect. Multi color/material is definitely the next frontier. Still have my beloved and heavily modded CR-10 BUT saving my money for a core XY replacement - unsure who that will be yet, but looking forward to regaining some bench space.

[@ivan-j4l9x]

How does this printer compare to the bamboo labs x1 carbon overall. Disregarding size which is more versatile a trouble free? Am I better off saving longer to get the pursar?

[@Pixelplanet5]

you didnt mentioned one of the biggest reason why its not overpriced. Its NOT made in China and the people producing and building them earn a living wage in a first world country. In todays time where we get tons of junk from China on a regular basis im very happy there is a solid alternative you can pick.

Talking about purge towers and extra filament waste, is it possible to use infill as your "purge tower". I don't have a machine capable of multi materials yet, but for multi-colored materials like red and blue PLA, wouldn't using the infill be much more efficient as in most cases no one will see them and you don't have to retract and move the nozzle away from the print.

[@krollmond7544]

You can get rid of the purge tower, I don't know all the details.

[@rileywatt2963]

In the future, could you have made the eyes yellow in the slicer since that's the filament you were swapping out?

[@spinnetti]

needs full enclosure, at least for the build area. Feels like the Bamboo is the one to beat now.

[@Brandon-jf9cv]

You can use orca slicer to get gap fill on printers besides bambu

[@Raven-Creations]

What I'd like you to test-print: small (benchy-sized) multicoloured pieces. I've not seen anyone manage to produce small multi-colour prints on the XL that come close to the x1c combo in quality, even after a lot of tinkering. Printing large is one thing, but I don't always want to print large things. I want to be able to print multi-coloured key-fobs, baubles for the Christmas tree, costume jewellery etc. I also might want to print something large, but with a small multi-colour logo on it. I know you like printing large stuff, but I want a printer that can print small stuff too. I don't (yet) have a shrink-ray gun where I could print something large and shrink it. From what I've seen, the XL seems to have issues at material boundaries which are insignificant on a large print, but which stand out on small prints. If you can get it to reliably produce small multi-colour prints, I'll be placing an order. Otherwise, I'll be going for an x1c combo for a fraction of the price. £2400 (the difference for a pre-assembled model) can pay for a lot of poop

[@marlonjareck7367]

I was almost afraid Prusa would lose the competition against faster printers, but in the end this machine is faster (at least with less waste!) than those with just one print head. Wow. Multimaterial prints are coming!!

[@peterwalker5413]

Regardless of those that complain about this printer being plagued with issues or not ready for release. It works perfectly! It is almost 99% user assembly issue or misconfigured slicer profiles. The profiles in slicer need to be tuned due to the temperatures being set high to compensate for IS speeds… but, that is not new, everyone should be tuning their filament profiles per roll in slicer before going all in on prints that take hours or days. Yes. Yes. You can say I am wrong. And yes I will disagree and double down on what I have said. This printer works flawlessly if you do exactly what is stated in the instructions. I am not a Prusa mafia fan boy and I will be the first to point out a flaw on any Prusa machine if I find one. As for the Prusa being the only 5 head printer… I thought that E3D was trying to sell one years ago… just didn’t sell do to true hardware and software issues. Either way great printer would buy another 5 head if I had room. If looking/waiting for the MK4 & MMU combo… don’t. Just buy this instead. You will spend more, yes. But well worth it. Despite what those that complain. There are more users with completely perfect XL printers out there. You only heard about the problem ones and very very rarely about those that work as intended. Always follow the instructions… take a second and reread them. Read the comments in the online instructions manual. Many of time’s we see things from a different point of view than those writing the instructions. Usually an engineer of sorts… once you wrap your head around it and see the instructions from a different angle it as if a light turn on. Eureka! 💡 😂 it’s just like back in the days of the mmu2. People just couldn’t wrap their heads around it or the troubleshooting instructions. Once you did understand what they meant and why they meant it. It worked flawlessly every time… as long as you didn’t use crap filament. But then back, then Prusa / Prusament was the de facto standard for quality filament while others were struggling to get +/-3 @175. If on the fence… don’t be. Waited for 3yrs and almost didn’t buy it once the reviews came out from the minority. Glad that we kept the order. ❤❤❤

[@naybordesign]

Very informative and enjoyable video. I would like to see if there are enclosures available for this printer. That would be the icing of this printer.

[@casen2007]

Is there a 3-D printer featuring a head changer with nozzles of varying diameters, allowing the use of smaller nozzles for detailed work and larger ones for areas where detail is less critical, or employing a larger diameter for infill and a smaller one for outer layers to enhance printing speed?

[@swashbuckle3713]

The XL hardware supports that already, but the slicers aren't there yet.

[@templarnato]

How is it compared to your Voron, ignoring the tool changing. I am really on the fence because most of the MM prints I have done are purely novelty items so it is quite a lot to spend just for that. I do have a MK3S and love Prusa so it is hard to move on from them.

Great review, good to see you not say it's perfect or the best printer out there because that (as you know) doesn't exist. $4,000 is a tough pill to swallow for me and maybe one day when it hits the $2,500 range it would be an interesting printer for me.

[@FrederickBorne]

Just paint the blood yellow and add a pause to swap colors. The slicer doesn't need to know it's a different color.

True, but the slicer OFFERS that functionality, and I tested it.

[@shpadoinkle_wombat]

Please test loads of multi material, please include couple weird combos like PC and TPU or PP with PVA supports. In general I'd like to know how is it with large prints out of ABS, ASA, PA... is lack of enclosure a problem? Will purge tower work with PP, which doesn't stick to anything, or soft TPU, that barely holds its shape?

[@bobbond8232]

I'm a newbee to 3D printing and I appreciate your honest reviews and love the fact that you show the positives and the negatives. I'm trying to decide between the Bambu Lab X1 Carbon and the Prusa XL. I love what Bambu Lab offers for a user that just wants to print, not tinker and its enclosure. However, I find that Bambu Labs' X1C's build volume is so darn small. I love the bigger build volume of the Prusa XL and its 5 extruder heads which renders way less waste but would have preferred the Prusa XL in an enclosure. Would that make a difference in the quality of the prints? In your opinion, is the Prusa XL to much to handle for a first 3D printer purchase. Its price tag is hefty for a first purchase. Is there a chance that Bambu Lab would release an X1C with a bigger build volume? You feedback would be greatly appreciated. And yes, I did Like and Subscribe!

[@liamventer]

Joel great reviews as always! People comparing this with the also excellent Bambu Lab printers are missing these are two very different printers with different intended uses and customers. I cant print multimaterial (only multi colour) on a Bambu Lab..and I infortunately cant cost justify this for just printing ornamental stuff. I need a multi-material printer with an enclosure for printing high temp nylon, ASA and ABS. Looking gorward to the reviews on the rumoured new Ankermate V6, 6 tool head printer (not sure how reliable this rumour is) and other tool changers no doubt soon to come on the market.
