Prusa MK4 Full Review: An awesome 3D printer, but is it competitively enough in today's market?

[@davecrabbe4579]

Maybe the best review of the MK4 I've seen. Their firmware, especially their networking performance have really hurt them. It is not even close to the standard in today's offerings. The "fast" benchies have really cut corners in terms of infill and layer height and shows that Prusa is willing to 'bend' the rules to get a fast number they can market. I think a solid printer for a bedslinger and anyone will generally be happy with its performance.. (except for the lack of better network connectivity).. but I'm surprised they didn't stop at the MK3S+ and create a new form size like this with a 4 post frame core xy that can easily be enclosed and so they can finally get some experience with this kinematic model. . I've worked with the X1C for about a month and the local network (wireless) features are just light-years ahead of the ESP-based Prusa design.

[@DD-sw1dd]

Agree. The upgrade to the mk3.5 or 3.9 is so expensive it makes me believe they don’t really want ppl to use the upgrade path….but also wanted to stay in line with their upgrade philosophy. Possibly due to any issues that may arise due to how the input shaping works (no accelerometer. Just calibrated for the printer) and the fact that the hardware isn’t exactly the same as the mk4. The motor, frame, thicker Z axis rods, steel mb box, and all the other differences in structure with the plastic make a difference in printer resonance frequencies. I bought a MK4 kit…but mostly bc I wanted a 2nd Prusa followed by the new hot end (easy swap nozzles/heating elements, all metal tubing),and easy maintenance (love board breakout mb). Also, if I wanted to sell my MK3s I’d end up spending less money than an upgrade to the 3.9 which doesn’t even have the motors for the price…..and I’d have a full legit MK4 (exact same frame). I don’t really care about the speed thing. It’s mostly about reliability for me with these printer….but that’s not to say I wouldn’t want more speed. It’s just 4th in my list of priorities behind reliability, safe to use while developing patented designs (no cloud bs as the primary feature), largely open source parts. It’s my mini-van printer. Plan on building a 350 Voron in the future to be my drag race toy. That’s probably when I’ll sell the MK3S+ after I’ve printed all the ABS/ASA and got it dialed in. PS. Wondering if Ethernet connection helps fix the network issues. If not, I hope it’s just a software issue that will be fixed. Otherwise I’m sure ppl will be fabricating rpi octoprint upgrades in the future. Just really don’t wanna go that route. Haven’t even done it to my MK3s+

[@davecrabbe4579]

I bought a Pi4 when I got my MK3s+ kit and used OctoPrint from the start. It is amazing. Much better than the networking in the MK4, from what I read. Would never be without it now.. Was hoping the MK4 networking was better than it is. @@DD-sw1dd

Considering how long this has been in development it’s a bit of a let down. Although if Bambu Lab never formed and the P1P or X1C never existed, it would actually be THE printer to beat. Unfortunately for Prusa they did and they do.

[@kneel1]

i mean they are both great and think its still a solid printer for any Prusa fan.

[@TheZimberto]

If it hadn't been for Bambu, we'd still be waiting for the MK4. The fact that it still isn't finished is proof of that.

[@c0mputer]

@@kneel1 I think you’re completely right. It’s a solid printer for a Prusa *fan*. Someone who will only buy Prusa will get a great printer because it’s an upgrade. For others who don’t care or don’t know about Prusa will see what you get vs the price and I could easily see it not being worth it for them. If Prusa knows their fan base will buy anything it almost seems like they’re taking advantage of them. Prusa isn’t making it super easy to defend them against Bambu in my opinion.

[@ChimpyChamp]

I was looking for a machine for a long time that checks all the boxes the X1 does, so I bought one and it's simply a fantastic printer. I did heavily consider the MK3 given its reputation but I just couldn't justify the price, that and I have always been put off Prusa machines due to his ragging ego, he plasters his face all over his products and I see in this review even the software interface isn't spared this time. With my X1 I don't have to be constantly reminded of persons name and face while actually using the machine, and I also don't get a pack of gummy bears in the box that make me feel like a five-year-old, the X1 is a more professional machine that doesn't patronize its customers with gummy sweets and constant name and face bombing , and for that I'm very glad.

[@kneel1]

@@ChimpyChamp i dont understand that weird Prusa-hate from everyone. Who cares if his face is on things the printers are awesome. Its so weird how people cannot control their own hate, and have no ability to ignore what doesnt apply to them. I own both Prusas and Carbon X1 - Bambu gets alot of hate too for stealing technology. It seems people pick one side. Just enjoy printing and it doesnt have to always be an "us vs them" mentality.. This was the case with Apple vs Microsoft many years ago and while everyone fought about it , I used both and still to this day use both OSX and Windows daily for different things.

[@thomasnox1141]

I think Prusa should start manufacturing in Mexico to cover North and South American market

[@omegadeepblue1407]

@@thomasnox1141 As a mexican i would really love that, maybe that will end with the reign of the Ender 3, because the Ender 3 has a big cult following, maybe two of the first 10 mexicans you meet are not people but Ender 3's. In my opinion the best place for Prusa to manufacture on México will be the state of Tamaulipas, that state is the neighbourh of Nuevo Leon (the state where Tesla is going to install) and has the biggest conection with the north american border and Texas, it also has a great industrial port for shipping and exportation. The reason why i choose Tamaulipas and not Nuevo León or Baja California is because Nuevo León is already infested with a lot of manufacturers and companies that are fighting to be on that state meanwhile Baja California is "China 2", not joking, for the same reason chinese say that the best chinese food outside China is on México. Tamaulipas will be a cheap and good option for Prusa, there are not really big companies there, the main drawback for that state is their bad fame, between 2006 and 2018 Tamaulipas was one of the most dangerous states (not as dangerous as Chihuahua but it was still dangerous) due to the narco wars, probably Tamaulipas is the reason why Texans have the idea that Mexicans are walking raging machineguns. However that is a thing of the past (with this i'm not saying that Tamaulipas is now heaven but now you don't need to stay in your house before 6:00 pm in order to be safe, is not like Oaxaca or Chiapas, those two are literally condemned).

Business's know they can defray costs through tax breaks so a bit dear but a whole lot more reliable with parts that can be readily sources at reasonable prices and easily installed. I own a Prusa and know why I bought it and know how good (read reliable) it is. I've recently bought a used one that I will upgrade and plan is to buy a third. There's my mini farm right there. They are a great printer and as everyone says, they just work. For me the question isn't are they competitive; it's are they worth the extra money. Yes, for me they are a no brainer.

[@tvideo1189]

I think of Prusa printers like I think of Simplify3D slicing software. Top of the heap in the past... but that was the past. There are WAY too many printers out there now giving Prusa performance at 1/3 the price. As for slicers, Simplify3D sat on their hands for literally years before updating and when they finally did update it was actually laughable. Really just pathetic when you see how far beyond Simplify3D all the FREE slicers are nowadays. Ironically, I now use PrusaSlicer as my go-to slicing software although none of my five printers are Prusa.

[@theglowcloud2215]

The slavish adherence to the Prusa brand among a certain number of people really perplexes me. I bought a Prusa Mini in 2020 because it seemed like a fair value, but then I discovered its shortcomings: namely, the extruder and hotend. Add to that the 3D printed parts, which on the hotend weren't holding up well until I reprinted them in ASA, and I come away feeling that Prusa makes mediocre products. The MK3S is probably better, but it doesn't justify its price anymore. I appreciate Prusa's commitment to open source, but the value proposition of their hardware just isn't there.

[@manekdubash5022]

Great review, thank you. Very honest. You could have added another criterion: my preference for Prusa is also driven by its open source foundation, which helps drive innovation. It's also a European firm and, even here in the UK on the edge of Europe, lowers shipping costs and makes a welcome change from the usual "design anywhere, build in China" model.

[@justinl.3587]

Honestly I love the MK4 and the Bambulab equally. However, I will always refuse to print so fast on either of them. I have set them very low with print speed. Hopefully this will allow them to last a lot longer with less maintenance.

[@EEEEMMMMKKKK]

That Nokia example was funny 😂 But i can’t agree. While Klipper is now a synonym for speed if you ask a electrical engineer if he want a hardware(printer) to be controlled by a firmware running on specialized board or a python application running on a general purpose operating system talking to a microcontroller over usb(klipper) i bet he chose the former. I am not saying the klipper is bad i like it but the closed environment like on device running marlin has a lot of advantages over general purpose os. And marlin based printers are running slower only because they are running on budget cpus. We can’t know but bambu lab printer’s probably not running a general purpose os either.

[@felixyasnopolski8571]

bambulab machines are exactly running klipper😂 they made a near-perfect combination, so all moves are calculated on linux with python in advance, with respect to input shaping and pressure advance, then klipper sends it to a mictocontroller which runs klipper firmware and have quite nice buffer for those moves; it gives you realtime control over the hardware, since the general purpose OS doesn't need to be realtime

Prusa has one huge advantage. It’s extremely reliable machine and it is easy to fix. I just moved from Europe to Mexico and three of my printers were destroyed in a shipping process. I could fixed them all by myself. I can’t do this with Bambu. When you do printing as a business you need reliable printers and Prusa definitely delivers here.

[@Peardropsldn]

How

[@oleurgast730]

Actually I am not so sure. While Klipper is a very powerfull firmware, for many users the functionality is overwhelming. Actual Marlin supports Input shaping (and Linear Advance was supported even on the mk3 without s and +). Yes, you have more options in Klipper. But what matters is not the options you have - but the result you get and how comfortable it is to get it. Esp. for persons getting into 3d-printing. As the Bambulab printers show, it does not matter, if you use Marlin, Klipper or reprap - they use neither but their own closed source firmware. Successfuly. I am quite happy, there are multiple firmwares - esp. the open source ones. Thei all have their own advantages - and ideas from one are transfered to the other. So comparing Marlin to Symbian does not realy fit.

I'm so torn. I'm a happy Prusa Mini user, and am looking to get a larger format printer. I was hoping the MK4 would be that printer. There's just so many downsides though. It's half baked IMO, and not as good as it could be at all, especially for the money. That said a Bambu is hard for me to consider, as I'm very much opposed to having to use Bambu's cloud to have a functional printer. That alone is nearly a dealbreaker for me. It doesn't work with Octoprint, at all, which is IMO stupid, given how flexible and awesome Octoprint is. It also feel like they are getting free use of PrusaSlicer and Slic3r's hard work without really giving back at all. Those 3 things make me very feel almost bad about considering a Bambu at all, but the features, quality, and price are appealing despite those IMO extreme negatives.

[@Traitorman..Proverbs26.11]

The Bambu extremely large ENCRYPTED log files is my primary deal breaker. No control of what information they leech from my computer.

[@printing3d722]

Aurora really had to balance on this one. Great review, and a wake-up call for Prusa. However, one thing that many consider pretty important she didn't mention is that Prusa is still open source. I do see a lot of complaints out there about the closed system of the Bambu. Don't get me wrong, I'm looking at buying one for the AMS ability and to try out some of the new features they offer. And, when the MMU3 is available I will try that after owning an MMU2S. I currently have two MK3S+ both were assembled from kits, one with MMU2S, a Mini Clone, a couple of Tenlog DL3 Pros, an Ender 3 90-degree belt kit, and a JD Maker Magic so I've been around the block a bit. With the Prusas, I can fix anything that goes wrong and replacement parts are readily available. Also, upgrades are available for older models as new ones come out. For me personally, these options carry a lot of weight. What I'd like to hear about is what issues Bambu owners have had that required them to have to return the printer for service, if any. Again, not trying to knock Bambu, just wondering. Is self-repair or upgrading possible?

I think that the mk4 is the pinnacle of what a bed slinger can achieve reliably. It’s a fast and convenient workhorse, maybe the future will be core xy for prusa, scaling down the xl, but maintaining the multi tool feature, maybe they will continue using marlin, extracting the last drop of performance out 32bit controllers, or release some add on like the sonic pad from creality.

I like their products, support is very good, upgradeability of your device (instead of buying a complete new one), open source 8which brings a lot to the 3D printing community, even if "others" use prusas work to build upon and then put a patent or TM on it to cash in), no "always online" drm, easy to connect with octoprint (prusas own system is still in beta as far as I know...), the only company which has put out a sustainability report and even company accident statistics (very rare)... I proudly finance the prusa company instead of a state own chinese one. The review is still interesting. And I still find that "first perfect layer" amazing (having a prusa mini here, so I dont know the struggle of adjusting the bed at all), which runs entirely automatic.

[@OccultDemonCassette]

Will you be doing a revisiting/update video of this after the firmware updates for faster printing and input shaping and all that?

[@beforethebigbang892]

Im interested as well

[@justsomeguy471]

hello! out of curiosity, on the part where you printed the first layer on the P1P, did you use the default profile, or did you increase your extrusion width on the first layer at all? i ask because that came out super clean wow

[@AuroraTech]

Yes, I just used the default profile without making any changes, except selecting no-brim.

[@justsomeguy471]

@@AuroraTech thank you :)

[@lukaszbien2904]

Thank you for quite detailed review, I decided to get MK4 kit as my first 3d printer - mainly for quality reasons, supporting company in Europe, open source approach, no need for cloud, and history of support for previous versions. Shipping to UK was around 20USD - so considerably less than USA.

[@YigalBZ]

Thanks for the good video. However: You should have mentioned the support as pro for Prusa: They have 24/7 support on line. What would one do with Bambu when something goes wrong? And things go wrong sometime. I have Prusa Mini, and their support saved me few times. However, the MK4 is not good enough as it should have been.

[@TheStickyBusiness]

I love your reviews- I would love to see more resin printed related stuff here too.

[@KevinOsborn]

I agree with many others here, that this is a most excelllent, fair and balanced review. I personally didn't do the math and did buy the upgrade (and came to the same conclusion that I should have bought the mk4 kit) but I do like my new Mk3.9. The usablity is dramatically increased. Also agree that Network setup and performance is a serious disappointment. Also, a perennial problem is the filament sensor which is or can become quite finnicky

[@blackjack0863]

I think it is a day late and a dollar short. They just did not make the jump that Bambu has.

[@electricalnguyen]

very nice video. Among 3D printers up to now, which one has the best accuracy in X-Y printing?

[@JohnOlson]

Prusa MK4 wifi setup is definitely cumbersome, but I've been seeing these recent Klipper-based printers using MKS boards leaving the root password as-is. People throw these on networks and immediately expose themselves. Prusa can definitely fix the wifi setup, but I'd trade that any day vs "throw it on the network" with default "root" and "makerbase" password.

[@mofo78536]

An NFC interface may help with setting up as you won't need wifi or ethernet to do the initial setup that way.

[@johnfaustus1]

How does one expose themselves by leaving the default user/pass on their 3dprinter connected to their own home wifi? Are they exposing the printer to their wife and kids now? What nonsense are you talking about. To access the machine, you'd have to access your home network.

[@JohnOlson]

@@johnfaustus1 google search “default password legislation”. Look into security of iot devices which a 3D printer is IF you put it on your network.

[@PatJones82]

5:37. My MK4 cools to 170 before moving to the next step, leaving nothing on the print bed. Not sure why yours was moving to the next step before cooling to 170.

[@thegps7197]

Great indepth review. Not impressed for prusa to supply 2 gcode files showing the difference in speed but rather than printing faster they just changed how it was printed. Clearly the printer prints well but at that price it should be better. Shouldnt have 3d printed parts for construction, no excuse for that anymore. The mk4 should of been a smaller xl, not quite sure how they made the decision to develop a core xy for the xl and think it was fine to keep a bed slinger for the mk4 at this price point. Always greatful with your honest reviews

[@mvadu]

The 3d printed parts are probably a feature. It is actually printed on mk4 itself, and you can see the final quality of the print even before you boot up the printer. It also gives the user an option to customize the printer with different colors etc.

[@JGW5000]

As much as I wanted to get the MK4, the dismal Wi-Fi capabilities are a deal breaker and have me leaning towards looking elsewhere. Thank you for the excellent review

[@whiskeyinthejar24]

I feel that its very easy to gloss over the support, knowledge base and open source system you get with a prusa. I bought an anycubic kobra for my first printer. I wanted an mk3 but it would have been 6 months to save up. I was learning by printing the usual junk, but also prototyping and learning 3d design for my business I want to start. 1 month in I had designed a large enclosure. 27hrs in to the 40hr print, the hotbed thermocouple died. Contracted anycubic through their local eBay store that I bought it from. Support was helpful, after some checks, they agreed to ship out a new hotbed and print sheet. After a couple of weeks I decided to add on a new thermocouple myself after researching what type it may or may not use. Another week or two later I get notified that my hotbed had been shipped from china. 4 weeks later it turns up. Nearly two full months to get parts. With a prusa i could have just looked up the bill of materials and ordered the right thermistor. Or ordered one from one of the local non official? Prusa resellers in Australia. Or express shipped it from overseas at my cost. From most accounts I've seen, creality are even worse. One of the guys on youtube with a faulty K1 has had zero response from them at all, email, website, social media etc.

[@alex.germany]

Very good and objective review. I'd like to see an update because a lot of have updated since. Most reviews are from the beginning. The software is in overall much better condition now.

[@44492611]

That comparison of the llama prints was really impressive.

[@TommiHonkonen]

what is the mechanical advantage of doing 10 minute boat tho ?

[@wrxsubaru02]

Its kind of sad how Prusa got comfortable instead of trying to stay ahead of the competition. Hopefully they can adapt before it's too late.

[@thimblemunch24]

I would buy something else after seeing this review. Thanks

[@hodanotyoda]

I see that you have the new K1 sitting on your Flexi Desk, a review video coming very soon?

[@AuroraTech]

Yes, coming soon... want to do more tests on it before I release the video.

[@madogheli6372]

I can’t wait to see that K1 review 🙏🏻🙏🏻💨💨

Great technical review, sadly the conclusion doesn't consider the work done by companies like Prusa for the 3D printer ecosystem. Most of the competitors cited will take from open-source and close source their work, and dump the price. For the consumer, it will result in a performance printer at a good price, but this is also a behavior that will kill the competition, innovation, and quality in mid-term.

[@joeking433]

I have the Anycubic Kobra and it has been a dependable machine. I'm really impressed!

[@arthurtorricer4544]

Also I am looking for the California company which makes the filaments you use and who sponsored one of your other videos

[@suntoxx9667]

Printed parts is what slows their production down? ;)

[@GarranGossage]

Thanks for the great quality review! I can't wait to see your Creality K1 review.

[@danielrogers6090]

Awesome informative video buddy, good luck next year as a freshman you will do great 👍

[@jessefurqueron5555]

Did ya’ll by any chance have any commentary on Mk4 wired Ethernet functionality, or perhaps I missed it?

[@PixelForgeLab]

Hi there ! how do you print the 1 layer test ? can't find anything online that works, most of them have more than 1 layer

[@magicmanspaz]

I had to pay shipping on the x1c in Australia yet if i buy parts of filament its free shipping over $77au???

[@janpetersen8441]

Firstly, congratulations on your graduation, and a really well written and delivered speech. I found your closing remarks on the MK4 review very well thought out as well, although I half expected you to end with “Prusa’s future is TBD”. I feel the launch of the printer rather rushed. I understand the hardware was in development for several years. But the software side, as you also found, was clearly rushed. I genuinely think they where caught on the back foot, and had to respond. I understand why they stuck with the i3 style printer. As Joe said, being able to upgrade their printers, is a core value of Prusa. But it is like Ford to still provide upgrades to the Model T. As some point, you have to move past the history in order to bring true progress. I’m not that concerned with the single CPU though. I think that the RepRap movement has reached a level of commercialization, where the open source philosophy is seriously challenged. We see it in not only printer design and closed source printer firmware, but in printer parts like hot-end patents as well. Prusa sticking with Marlin, and heavily modifying it, gives them a niche in the market. As long as the CPU they use is designed to manage the load, it’s fine. The slow WiFi module I think comes down to cost. Plain and simple. A replacement Einsy Rambo board for MK3 is a whopping $119! I can only fear what the cost of the new board might be. They are challenged by the business values of prioritizing local suppliers, and supporting the local economy by assembling the printers in they own factory. It’s a valiant goal to have, and I do commend them for sticking with it. It’s like supporting local farmers by shopping at the local farmers marked, even though produce at the grocery store is cheaper. But there’s no reason why they couldn’t create an assembly line at Printer Solid for example as well. After all, assembling the printer as close as possible to the customer, is a valiant business goal as well. They do have a US distributor. They bought Printed Solid, which is now the US Prusa distributor. Why they don’t ship MK4’s to US customers from Printed Solid, is beyond me. That said, I do have a MK4 kit on order. Not because I think it is a sound investment. It’s an emotional investment. I don’t expect the MK4 to be my go-to printer, like my MK3 was. These days, my go-to printer is my Voron 2.4. And I don’t expect the MK4 will change that.
