[@jothain]

Nice. Very nice. MK3(S) owner here. I've been very with my printing years in past with it, but it's obviously quite dated these days. I've been planning about upgrading, maybe in the winter and honestly I was looking into Bambu's. But I've seen some parts with them having ringing as much as MK3 and it was very disappointing to see. Now MK4 originally didn't get much of my interest, but if you've been focusing into dimensional accuracy and these new feats you're absolutely back-in-the-game for me. Reliability is something I was expecting already from my MK3 experiences. Excellent dimensional accuracy, minimum artefacts like ringing, good material support, ease of use, decend print speed and reliability. Those are what I want from my printer.

[@Prusa3D]

Hello, thank you for the comment. You can upgrade your printer to MK4s with a single kit. The upgrade to MK4 now becomes upgrade to MK4s. No need to buy two upgrades

[@CraftySven]

You get a better dimensional accuracy out of the box with the MK4 compared to Bambu, without profile tuning. Otherwise you can get them both to print the same for accuracy, with minimal tuning. The mk4 is definitely a step up in this area compred to the mk3 series

[@jothain]

@@CraftySven Yes. There's quite many good changes now in MK4S compared to good old MK3. Personally I don't give any credit to almost all people touting that XY printers are must and bedslingers are obsolete. Why someone might ask? It's because I used to work in sheet metal fabrication plants and even there in high accuracy and speed machines work piece was moved in many machines bit similarly as bedslinger printer. I don't see any issues in design if overall design is just made suitable for application. Some tend to forget that XY design might quickly thinking look absolutely superior,but many olso forget that one axis accuracy problem will very, very easily reflect directly into remaining axis accuracy too. To my belief next iteration that's needed in 3D printing is new axis that nozzle can turn in angle to create even more steep overhangs which is serious limitation currently in every single printer imo. They're surprisingly good,but they need to get better. Now this change will add weight to print head and I kinda suspect that corexy isn't best style to accomplish this. Many designs can work well. Imo it's very foolish to say everything should be corexy styled. Good overall design is what matters, not frame type/style that can be botched 🙂

[@BrianDavisDivis]

This is the very reason I chose Prusa: sustainability and long life cycle. Other brands will push you their new printers, Prusa just keeps supporting and upgrading the old ones as long as it makes sense. Compared to the usual consumerism, this is so refreshing. The printers shouldn't be fast-moving consumer goods, it should be a reliable machine you can repair and upgrade in the long haul. And that's where Prusa really, really stands out. So thank you, Josef, for keeping the spirit of DIY alive!

After upgrading to the MK4S, it's hands down my favorite gadget in the house again! The improvements are incredible-I’m amazed by the enhanced speed, precision, and overall performance.

So stoked to see this! Absolutely writing the book on reliable, well-considered and thought-through research-based design. My MK3S was my 3rd printer and while it's accuracy and reliability still beats out most all other printers at a similar price point I've compared it against, I was considering some kind of custom Voron as the MK4 didn't quite have the improvements and hackability for the price point. Now, however, I'm going to seriously consider those upgrade emails I occasionally get from you guys. It really seems worth it. Absolutely fantastic offering with this.

[@ShakeTheFuture]

I don't normally leave these kinds of comments, but I wanted to share my 3D printing journey and explain why I love Prusa printers. For transparency, I received both the Prusa MK2 and MK4 free of charge at some point in the past, but that doesn’t influence my opinion. I’ve also received other brand printers free of charge, so I’m comparing apples to apples. Over the years, I’ve used several printers, but none have been as reliable as Prusa. As a maker, I’m only interested in printing, not tinkering. Don’t get me wrong-I’ve used other printers that I liked, but none have checked as many boxes as Prusa. One printer I loved was the Flsun V400, but I experienced dimensional inaccuracies. I tried to fix it, but either I couldn’t or I didn’t have the patience to keep tinkering with it. That’s why I keep coming back to Prusa printers. I’m often sent different printers to try out, but in the end, the only ones I keep are Prusas. The only reason I got rid of the MK2 was because it didn’t have a magnetic build plate. For example, I’ve been working on something I call “Print Wave Metal Casting.” It’s a metal casting technique that involves printing a mold, then pouring plaster directly onto the 3D printer’s build plate and shaking the mold by running custom gcode. The Prusa MK4 has been the perfect printer for this job. It’s important to have a flawless first layer, which I consistently get with my Prusa MK4. I agree with what they say: Prusa printers are reliable and just work. So, I’ll definitely be getting the upgrade 👍

[@TheToonamiRevolution]

Its great how much faster updates seem to be coming out for your printers. It has caught my eye once again as your printers are once again being competitive. I care A LOT about print quality, but this printer here finally feels like you're getting back to a good place. If it just had built in camera support I think I'd be sold.

Really frustrating.

I wish you nothing but the best. I hope one day I can be back with Team-Prusa printing :)

[@tomtlc]

To be honest, I never did consider getting a Prusa printer. BUT now that this MK4S came out and I think most important thing for me is a perfect first layer and layerlines, this is it! After watching competitors boasting about speed but the final print quality isin´t there. If you think about it, yes it´s pretty expensive but it is made in EU, long lasting updates, support, quality...you name it. I´m tired of my secondhand modified Ender 3. I do customer works and I find myself fighting with my printer when I could be just printing perfect prints. If I could afford a new printer, it will be Prusa next. I´m impressed.

Joseph, I LOVE prusa and see you all as the top leading brand period. The quality, the hard work, the support, the tracking of every single thing. You literally pour your heart and soul into every aspect and detail of prusa and prusa products. However, that being said, I can’t help but see the mk4s as another upgrade to a 10+ year old design. Over a decade has felt like an upgraded patch to the same look and feel we’ve used forever. Since the mk2, we’ve seen the same rod system, same belt system, near similar parts, and same basic functionality and structure. The design has been left out over and over and needs a serious futuristic overhaul imo. Something so incredible and produces such high quality prints, needs to also look the part. For us technically inclined we could care less, but for everyone else, it needs to look as good as it works. Instead, to some it looks intimidating. For us engineers we don’t really care how it looks as most engineers don’t work in design. I completely understand that the design has to also follow function. It’s time to look into a new build. A new look and better overall design. You can still keep costs down and still look amazing! Now, I’m not offering to design the new look, I’m just suggesting it’s needed. (Though I’d gladly do it for one and some filament lol….but again, not my point). Please consider the next upgrade or major revision to also create an all new shocking look to show your strength and quality we’ve all known and grown to love. Keep printing!

@@dubsativa180 afraid, this isn’t a Porsche here. While it’s a great machine, it needs to look inviting, not intimidating to new users. It needs to change and evolve as tech evolves and not look like you’re putting a bandaid on every year. While that’s not the case here and a bit extreme to make a point, prusa ‘s tech is amazing. Point being, the rest of the machine needs to match the part. It’s why we aren’t driving old Porsche’s and driving EV versions that self drive today. If you don’t stay up to date with tech, you die out. You have to be competitive, and look the part. There is plenty of room for innovation and it’s time for change. We’re paying $1000 for a machine that should feel like a new Porsche and look it too.

Please add "Cooldown" to the "Filament" menu. Super easy, and super practical🙂

Prusa has become Prusa Lab

Sounds promising. I like to know the content of the upgrade kit. Can't find any information about it. The only thing is, that the most noise of my MK4 is not comming from the part cooling but from the hot-end fan. The part cooling fan is usually not noticable. Since the "stealth mode" is not working and the part cooling fan makes a lot of noise the upgrade will not make the printer more silent...

Good improve with MK4S congratulations! But I think that you have to sell mounted for the price of kit to catch the competition
