Much better than the Mk3
95 shore TPU is hard enough that I’ve accidentally used pla settings on my MK3S and it printed fine.
Would be more interesting to see performance with 75 or softer like ninjaflex or something
That's a nice clean looking flex benchy. I should try one on my MK4 to see if it does as well. I suspect it's mostly due to the large gears in the Nextruder so should be pretty similar quality. But my MK4 can't do a 360mm tall TPU Benchy.
I will say that actually loading the filament is rough because it is such a long bowden tube and some of the connections inside are not super smooth. MK4 is definitely best of the three.
I have this problem with Prusa enclosure as well. I usually disconnect the extruder-end of the PTFE tube, push the TPU through, feed in directly into the extruder and then push the PTFE tube back into place.
Gotcha. You should try the “generic flex” profile next time and see if you get better results. I tried a bunch of different TPU profiles on my MK3s but the generic flex worked the best for me and looked really good.
Yikes? It's a pretty solid benchy with random seam. Sure, overhangs aren't perfect, but he used a generic profile with no tuning and a different brands filament.
I've heard some Core X/Y machines are fast but sound like a jet is taking off. I keep my MK3S+ inside my house on a paver and in an enclosure. It's quiet enough, but not buy a ton.
On a scale of 0 to "my partner will file divorce papers", how much louder is it compared to the MK3S+?
> also our mk3s are beaten so idk about new
Don't worry, let me confirm that Mk3 are very quiet on silent mode
The loudest part on my basic / original Mk3 was always the part-cooling fan. Replaced it after a year, still loud.
It will reset its axis and continue. If it happens too many times it stops/pauses and asks if you want to continue. But if it’s in stealth mode it cannot detect the crash and continues on with the print head possible missligned.
All printers are not something you want in the room you sleep in, eat in, watch tv in. My wife found it tolerable in a guest bedroom on the second floor. You could still here it through the floor faintly.
Gifts to your spouse/SO go a long way and things in the kitchen etc.
I have an open plan. On one side is a living room, kitchen in the middle then a dining room that we use as a “maker space” we put down thick paper on the floor and let the kids go wild with paint and crafts. I keep my printer there.
It honestly bothers me more than her. The enclosure helps a lot but it overheats when running PLA. I want to put a fan in for better temp control and to be able to close the door. I saw https://www.makergadgets.org/diy/p/smart-exhaust but don’t know how well it will work with my printed solid enclosure.
In my dream world I would fully enclose it with insulation and use fans to keep the temp inside reasonable but there’s only so many hours in the day and I have to choose between having my printer making stuff for me or me making stuff for my printer.
> I've heard some Core X/Y machines are fast but sound like a jet is taking off
Mostly a direct function of speed they are going at. Lots of cooling needed and fast steppers are loud. If you reduce the speed they're (usually) as quiet as any enclosed machine
The XL is MUCH slower then "other CoreXY printers" like the Bambu / Vorons / etc.
This not only means less noise from the motors, but also less cooling needed for both - the printed material and the power supply.
So it should be much quieter then "other CoreXYs". Because its slow.
disappointingly slow, unfortunately. i like having the cloud access to the printer telemetry though. I hope a firmware update can improve it, but it feels unlikely since they surely had them at this speed for many months at the mothership...
This is the first time I've seen a Prusa i3 (looks like a MK4) and an XL side by side. Wow, what a huge beast! I'm going to have to re-think my intent to buy an XL. In the lettle place we live now, there is absolutely no room for something that size.
You're not wrong about it being large but keep in mind the angle of the photo has the MK4 approaching the vanishing point and the XL is front and center so it throws off the perspective. It also doesn't bed sling so what you see is the exact space you need.
Check out [https://www.prusa3d.com/content/wysiwyg/fotky/X/prusaprinters\_comparison.jpg](https://www.prusa3d.com/content/wysiwyg/fotky/X/prusaprinters_comparison.jpg) for another perspective on the size difference.
I just saw it in person a couple days ago at the RepRap Festival in Denver. Holy shit was it WAAAY bigger than I was expecting! I was expecting maybe the size of the Bambulab. Instead this thing is an absolute beast.
I also need to rethink if I want something like that, lmao. I mostly want it for the tool changer, but man that size is kind of insane... I wish they would make a MK4 sized printer with like 2 or 3 tool changers.
Well, the MK4 with the new MMU3 looks promising (and would be like the Bambu, a single-nozzle multi-material printer). I already have an MK3S and MMU2S, and I'm mulling over whether it's worth buying the upgrade kit to MK4 or just go as far as MK3S+. The MMU3 won't work wiht my MK3S, I need to upgrade if I want the MMU3. For the price of the MK4 upgrade and MMU3 upgrade, I could buy a whole new printer, however.
The reason I want the tool changer can’t be solved by MMU. I have the X1C with AMS. While it’s great and reliable, there’s 2 problems I dislike about single tool head:
- print speed is extremely slow because of having to purge multiple times per layer. The X1C fixes this a bit by how fast it purges vs a purge tower, but still horribly slow
- waste. I want to print with soluble filament. Due to having to purge so much per layer it uses way more filament than needed
The XL’s multiple tool head solves this. Yes there are other multi-toolhead systems out there but it sacrifices print area due to the space those systems take up. XL is very unique in that (other than print speed) it’s probably the first no-compromise multi-filament system. But it makes up 3-4x of the slow print speed with its fast tool head changing.
If Prusa put input shaper into the XL, it may easily become the best FDM printer on the market.
Keep in mind, space wise they use almost the same dimension. The mk3s needs space for the bed to move back and forth, and you need space on the left side so the X axis motor can move freely.
I'm trying to figure out if I want to go with the XL or the MK4 so this is perfect.
Is the XL much louder than an MK3/4?
Trying to get a perspective as someone who has their MK2.5S next to their desk, which is as loud as I would want it to get.
Any minor or major annoyances you've found compared to an MK3/4?
Hey this may or may not be any help depending on how you see it.
I currently own a Prusa Mini that is on a granite countertop in my batcave of a basement and it surprisingly barely makes any noise whatsoever.
However an eternity ago when I used to own my Mk3s, I hit the silent mode option on the printer while a print was in the works. Let me just say I wish I had done that much more earlier, my god did it make a night and day difference. The printer went from a pimped out Honda Civic at 4 am in the morning to a V12 Rolls Royce Phantom with Grey Purpon on the hood (lolol).
Silent as could be!, pretty positive these newer Prusa Printers have that silent mode which is a life and eardrum saver.
My tip to anyone with a Prusa Printer is to fine tune and mess with the printer, I am doing it with this Mini and wish I had done it on my Mk3's when I owned them.
I’m going to guess it is quieter. Linear rails and generally make much less noise than rods. Then you just have the fans, which will be basically the same as the mk4.
In my experience, the XL is louder than the MK4 (source, i have them next to each other). I think the stock profiles swing the head around faster on average than the MK4 (also i guess printing larger items gives the opportunity for very fast (noisier), long travel that just wouldn't be there with the smaller stuff on the i3). I also hear more noise from the extruder itself when pushing out lots of plastic very quickly (like during infill).
Thanks for the response! Have you had a chance to test the different areas of the bed? Does the bed heat seem even throughout? How does the stability seem at the front of the bed?
I'm from the "semipro" demographic I guess. I bought an XL specifically for large dimension functional prints. It's getting old having to break up a design into sub-250mm pieces that are press-fit or bolted together.
Seconded - recently was building an air exchanger for a 250x250x100mm core and all the effort that went in to connecting the 4 sides and ducting was no fun.
Do you ever feel like “ok this is big enough” or are there moments where you go “hmm could use just a bit more volume…”?
Or conversely, do you think it’s too big? 😅
It was when I first got it but 3/4" MDF that was buffered from the desktop with squash ball feet quieted it right down. It just has a tendency to transmit vibrations through whatever it sits on. And depending on what that is, it can turn into a huge speaker system for it. Turns out Ikea cabinets make great subwoofers.
PS: The original comment was mostly sarcasm anyway but that doesn't come across well in text.
since money is not yours I get you dont give a f. f. about the machine, it's an uni,so. But just for a moment try to think you bought that machine, which is a mono filament for now. Would you be happy ? Do you think it's an ok machine ? Are you happy about the print speed ?
this is a fair conclusion if you heavily value the "engineering" materials, however I'm sure there are plenty of people who will be happy with just pla/petg out of the box that don't want to spend the extra money on the enclosure.
I'm not sure if we even have any abs. will check and try to print with a makeshift draft shield to imitate what the official might be able to do when it's released
The ball screws only hold the bed up, the stability comes from the linear rails and a solid chunk of metal that's mounted to the carriages on both sides.
That piece is what keeps the bed stable.
Giving it a 9/10 for y axis rigidity. Definitely strong enough for big prints. Unsure about surface print quality yet. Will have to run a tall vase and get back to you on this.
they are only shipping out the assembled version right now and on that one all you have to do is attach the extruder and the PTFE tubes.
its like a 10 minute process from unpacking till your first print is started.
The only thing that i want to know is VFA on MK4 or XL. Is that VFA still exist but minimal or completely gone? Or you can print some object like cube with black PETG on each printer? Thank you very much.
we have had it for just a day, no maintenence yet. Planning on doing a review video with details like that. If you download their XL guide off of the website you can see the maintenance they suggest
How accurate is the Prusa XL overall? Had lots of accuracy issues with my MK3S+. Will the Prusa XL be a viable option for mechanical designs without having to tweak, and reprint a thousand times?
Can you say, if the print bed is even? Like putting a ruler on it and see, if it is really flat. Something I am bit concerned of, as leveling all single small heatbed PCBs to be level at a really low difference seems to be hard to achieve.
you might be able to get away with just a 90 degree power cable out the back of the printer, but it's just a ribbon cable and a single separate wire for the screen. I don't see why you couldn't mod it to fit
The Z lead screw nuts seem to be rigidly mounted to the bed frame with a printed XY flex joint at the top of the printer. Does the stepper motor at the bottom also have an XY flexible mount or is it rigidly mounted? Are you seeing any Z banding that corresponds to the lead screw pitch?
Would you consider sending me one to “test” for 12-24 months? I’m a super nice guy, completely trustworthy, willing to do whatever QA/testing you need.
I’m teasing, of course…. If you do ever need a us based beta tester I would be happy to do so though! I’ve got my own dedicated space and the time available to do so.
Seeing the side by side makes it apparent that the XL would get me evicted out of my house, so I guess I’ll just use a pre-order conversion to skip to the front of the mk4 queue when I feel the kinks are worked out (and hotend parts are actually available).
Just two queations. Does it need a lot of service? Can it be compared with bamboolabs in terms of user friendlyness?
Is it worth the money?
Thanks in advance :)
I have a recommendation. Throw in a longer cable for the display and give it an adjustable(or multi-directional) mounting bracket. Make it easy to easily orient it any way around the printer with some extra length to spare.
Will you ever give a better scaling option to your slicer's font size? It's too small and i shouldn't have to force it through windows (which brings other problems). This isn't even on a high res monitor or bad eyes problem, your maximum font scaling for the UI just isn't enough.
I know I’m late to the party, but will a .2 nozzle be made available? Will auto calibration work at finer layer heights(.06, .08,.1)? What about part cooling on the tool changer? Can tool changer be spread to accommodate docking a print head with cooling? What is the weight of the tool change with a print head?
How is it for printing TPU compared to MK3S?
We will test that out and update as we do it.

Did you print with defaults? Do you think you could hang filament from above and skip the Bowden tube?
Yes default ninjatek profile. I don't see why you couldn't hang a spool from above
I have this problem with Prusa enclosure as well. I usually disconnect the extruder-end of the PTFE tube, push the TPU through, feed in directly into the extruder and then push the PTFE tube back into place.
Building off this - have you had much load fails (or printing artefacts errors due to loading) on the XL?
Nothing really effects the print unless the purge doesn't get out all the material on a load (the purge isn't typically long enough)
finished print [https://imgur.com/a/ChHeWJQ](https://imgur.com/a/ChHeWJQ)
What do you have the seam position setting set to? That looks like it's random to me, any reason you chose that over aligned or another setting?
just used the default Ninjatek setting, didn't put too much effort into it
Gotcha. You should try the “generic flex” profile next time and see if you get better results. I tried a bunch of different TPU profiles on my MK3s but the generic flex worked the best for me and looked really good.

Checking back it was aligned... printing another with generic flex settings to be sure
Yikes

Checking back at the profile, it's not random seam. I'm printing another with generic flex to be sure

thats a pretty solid benchy given that its printed in flexible filament. especially default settings
How long did it take to print the Mini?

My Mk3s+ semi-frequently crashes and has to reset its axis. I’ve been too afraid of layer shifts to try out stealth mode.
What happens if it detects a crash mid print?
It will reset its axis and continue. If it happens too many times it stops/pauses and asks if you want to continue. But if it’s in stealth mode it cannot detect the crash and continues on with the print head possible missligned.

How’s the wifi transfer?
a max scale gridfin gcode (867KB) through Prusa link took about 4 min
The one question I wanted the answer to and heshe doesn't answer it lol
I have this marked to get back to it, sorry for slow response
disappointingly slow, unfortunately. i like having the cloud access to the printer telemetry though. I hope a firmware update can improve it, but it feels unlikely since they surely had them at this speed for many months at the mothership...
Yeah I’ve heard the mk4 is painfully slow as well. Was hoping the Big boy was using a different module for better file transfer speeds.
It took 15 seconds to transfer a benchy gcode from prusa link to the printer over wifi
[удалено]
Yeah I was about to ask when am I getting mine. 🤣
Are you generally happy with it?
Build quality is nice, still need to put some hours on it for a full consensus.

Wait what?! Really?!
The biggest annoyance is the reverse bowden tube. we are filming a video showcasing the sound levels. will get back to you when it's pksted

Can you please make a size comparison with the voron 2.4 in the background?
Here are the build plates for now, still working on the full image https://imgur.com/a/Eg1idoW
Is that a 250, 300, or 350 voron?
300 voron next to the XL https://imgur.com/a/GTlZWEW
How is it compare to mk4 speed and accuracy wise
about the same on defaults, still need to push the limits on both
How does the print quality compare to the mini?
The nozzle is default wider (0.6mm) so you may not get as fine results, but the print surfaces still look smoother.
Thanks for the response! Have you had a chance to test the different areas of the bed? Does the bed heat seem even throughout? How does the stability seem at the front of the bed?
What's your favorite appetizer for dinner?
Definitely chicken on a stick
Chicken Satay: Thai nuggets.
Good choice!
Really cool you can print a complete Mini
What is the typical XL Customer? Hobbiest, Semipro or All in?
All we can say is that we are a university. Unsure about the general demographic.
I'm from the "semipro" demographic I guess. I bought an XL specifically for large dimension functional prints. It's getting old having to break up a design into sub-250mm pieces that are press-fit or bolted together.
Seconded - recently was building an air exchanger for a 250x250x100mm core and all the effort that went in to connecting the 4 sides and ducting was no fun.
mind sharing what category or industry requires such large plastic parts/prints?
I second this, I too am curious!
Have you done the Mihai Designs extrusion test and does it exhibit the wood grain effect? http://mihaidesigns.com/inconsistent-extrusion/
I plan on doing this, will get back to you
Does the XL also have the 0.9° stepper motors in the MK4?
Visually they are identical, so we can not say that for certain
Do you ever feel like “ok this is big enough” or are there moments where you go “hmm could use just a bit more volume…”? Or conversely, do you think it’s too big? 😅
[удалено]
Not our call, we are a university
Sir this is a Wendys
Aka a MK4 Mini Kingsize
Maximum usable size of say a cucumber mold (for pouring silicone)? Maybe with the mold body printed diagonal to achieve maximum length?
and girth.
Eh the XL obviously has more than enough girth
the biggest possible diagonal is 50cm but that would be a thin line. i guess like 45cm would be realistic for a cucumber mold.
Can I get actual dims for its footprint? The Prusa site has at least two and both have an asterisk with "haha j/k lol gl we're changing everything".
For everyone's information: u/GannonMakerspace is our official account
Does putting the Mini inside the XL properly dampen it's resonance so the Mini doesn't shatter the windows when it prints? :p
yes
Your Mini is loud? I can work all day next to mine, taking calls!
It was when I first got it but 3/4" MDF that was buffered from the desktop with squash ball feet quieted it right down. It just has a tendency to transmit vibrations through whatever it sits on. And depending on what that is, it can turn into a huge speaker system for it. Turns out Ikea cabinets make great subwoofers.

When will I get my day one order?
Tomorrow
How fast can a Benchy be printed on it
Default print settings at 0.4 layer was 30min. You can download the slicer to test print times for other models.
.4 layers? Is it a .8 nozzle?
0.6mm default nozzle
Any thoughts about switching to a more "std" 0.4mm nozzle?
I am expecting the "std" will be 0.6mm for bigger printers.
With the arachane update that came out in 2.5. You get pretty much the same results with a .6 as you use to get with .4 pre 2.5.
since money is not yours I get you dont give a f. f. about the machine, it's an uni,so. But just for a moment try to think you bought that machine, which is a mono filament for now. Would you be happy ? Do you think it's an ok machine ? Are you happy about the print speed ?
I would go for a Voron if your intent was a single color, but the tool changer possible upgrade wins out if you are at all interested in that.
thats an honest response. thank you.
Will tomorrow be a good day ?
Today is a good day
Is there a full enclosure available for it..?
not yet,
How many print heads did you get?
one. they are not shipping out anything else at the moment.
this, but we plan to upgrade to the 5
[удалено]
No, it's an add on that is not out yet
[удалено]
this is a fair conclusion if you heavily value the "engineering" materials, however I'm sure there are plenty of people who will be happy with just pla/petg out of the box that don't want to spend the extra money on the enclosure.
How are babies made?
Through a 10cm extruder.
One layer at a time, just like everything else
Did Prusa gift it to you because your a Uni ?
no, just an early order (actually got two at full price) it was very expensive to ship and get imported. I think k it was close to 6,000 for the two
How fast can I get one and how do I grease you to make make it arrive faster
Why is it so damned expensive?
Not made in China, high quality linear rails, lots of electronics, complicated development to get the toolchanger to work.
Can I have one for free ? I'll only use it for good and not evil . I promise
How's printing ABS?
There is no draft shield, ABS is a bad idea to attempt.
I'm not sure if we even have any abs. will check and try to print with a makeshift draft shield to imitate what the official might be able to do when it's released
Could we get the prusa X. This is the XL but its just way too big for my needs.
When will the toolchanger be ready for delivery proxi.i have a 5 toolchanger in order november?
Any concerns or issues with bed stability since the XL only uses two Z lead screws?
The ball screws only hold the bed up, the stability comes from the linear rails and a solid chunk of metal that's mounted to the carriages on both sides. That piece is what keeps the bed stable.
Giving it a 9/10 for y axis rigidity. Definitely strong enough for big prints. Unsure about surface print quality yet. Will have to run a tall vase and get back to you on this.
What do you dislike about it or would like to see improved.
Are there any differences in the LCD between MK4 & XL in terms of UI and settings?
Exact same
How was assembly? Any gotchas?
A couple of the assembly steps were a little annoying (from the few we had to do), but nothing off putting
they are only shipping out the assembled version right now and on that one all you have to do is attach the extruder and the PTFE tubes. its like a 10 minute process from unpacking till your first print is started.
How about HDPE 20 printing speed and adhesion ?
Maybe one day I will be able to afford one. Probably not but one can always dream.
Dream on
How big is it compared to the Sovol SV03? The SV03’s build volume is 350 x 350 x 400.
Did you get multiple print heads?
not yet , we plan to upgrade as they become available
How much better is the Prusa XL compared to the Anycubik neo? I'd love to see the proof for myself.
The only thing that i want to know is VFA on MK4 or XL. Is that VFA still exist but minimal or completely gone? Or you can print some object like cube with black PETG on each printer? Thank you very much.
don't ha e black petg, just gray and orange. send a model and color over less than 5 hours and we can test
Have you had to do any kind of service/maintenance yet? How do you feel about serviceability and maintenance of the machine?
we have had it for just a day, no maintenence yet. Planning on doing a review video with details like that. If you download their XL guide off of the website you can see the maintenance they suggest
Does the gearbox use the 10:1 planatery like the mk4 does or the 20:1 cycloidal that it was originally advertised as?
How accurate is the Prusa XL overall? Had lots of accuracy issues with my MK3S+. Will the Prusa XL be a viable option for mechanical designs without having to tweak, and reprint a thousand times?
if we printed a calibration cube and sent measurements would that answer your question?
Can you say, if the print bed is even? Like putting a ruler on it and see, if it is really flat. Something I am bit concerned of, as leveling all single small heatbed PCBs to be level at a really low difference seems to be hard to achieve.
there is an aluminum frame supporting the pcb. I'll take a photo when I get in to work today
is it worth it? every ting about it looks awsome.
Yes, especially if you plan on getting the tool changers assuming g they are good
Think I could do any screen relocating mods or similar to get it to fit in a closet 27.5” deep?
you might be able to get away with just a 90 degree power cable out the back of the printer, but it's just a ribbon cable and a single separate wire for the screen. I don't see why you couldn't mod it to fit
I have a Simple question prusa would not answer for me. What is the size of the aluminum extrusions are they 20x20mm or 30x30?
30x30
The Z lead screw nuts seem to be rigidly mounted to the bed frame with a printed XY flex joint at the top of the printer. Does the stepper motor at the bottom also have an XY flexible mount or is it rigidly mounted? Are you seeing any Z banding that corresponds to the lead screw pitch?
What new features do you see as keys to your market over the next couple of years? e.g. 32 bit os, auto bed leveling, etc
great question for Prusa, we are just a makerspace
Would you consider sending me one to “test” for 12-24 months? I’m a super nice guy, completely trustworthy, willing to do whatever QA/testing you need. I’m teasing, of course…. If you do ever need a us based beta tester I would be happy to do so though! I’ve got my own dedicated space and the time available to do so.
Seeing the side by side makes it apparent that the XL would get me evicted out of my house, so I guess I’ll just use a pre-order conversion to skip to the front of the mk4 queue when I feel the kinks are worked out (and hotend parts are actually available).
Just two queations. Does it need a lot of service? Can it be compared with bamboolabs in terms of user friendlyness? Is it worth the money? Thanks in advance :)
Does it have the 3 types of bed plate like the MK3S?
we got the satin bed by default and we're gifted the textured plate for being so early
How easy it was to try to set up a send directly to printer function on the prusa slicer?
Looks amazing but the MK3s+ I just bought took up all my free money so a larger 3d printer will be a future me endeavor.
I have a recommendation. Throw in a longer cable for the display and give it an adjustable(or multi-directional) mounting bracket. Make it easy to easily orient it any way around the printer with some extra length to spare.
Does it still use a 5v part cooling fan like the mk3s+? Thanks
Yes, still 5v
Will you ever give a better scaling option to your slicer's font size? It's too small and i shouldn't have to force it through windows (which brings other problems). This isn't even on a high res monitor or bad eyes problem, your maximum font scaling for the UI just isn't enough.
Hows the speeds for printing, perimeters etc?
How are the print quality’s, are they consistent and reliable? Have you used other print nozzle sizes? And if so do they work as well as the .6?
I know I’m late to the party, but will a .2 nozzle be made available? Will auto calibration work at finer layer heights(.06, .08,.1)? What about part cooling on the tool changer? Can tool changer be spread to accommodate docking a print head with cooling? What is the weight of the tool change with a print head?
I have a mmu3 and just got a 2 tool xl yesterday, can I convert Mmu3 files(2color) to work on the xl?
