      Yes and no. If they have private investment or were publicly traded then yes the pressure for infinite exponential growth would force them to make crappier products until they implode or get bought out. The idea of shareholder supremacy that took hold in the 70's and has been f-ing us and the planet over ever since. If not then the only reason to grow is to help as many people as possible. They can grow organically as needed and keep doing their thing slow and steady. I don't know if they have outside investment. I don't think they're publicly traded though. I hope they never are because it will destroy the company.
      As it stands, I assume they don't need to sell more and more printers every year as long as they break even financially.

My Mk3 will become the support machine, still reliable after 1000's of hours work; all the upgrades are done, including Revo, but now's the time for change.

      @@testboga5991 it provides 2 grounds of conversation; 1) The message it provides 2) where his priorities are. Yes injection moulding is far cheaper on a mass scale which allows him to replace that entire room with just two or three injection moulding machines, and allows him to sell more printers at a cheaper price. However, that does not support the 3D printing message. Josef is a designer and a maker, his design is so important to how we the public, the rest of society, views this design he has created (with or without help is irrelevant, it's ultimately his design and his decision). If the parts were from injection moulded parts, even if you went the further length to added artificial print lines into the moulds to replicate the effect of printed parts, it loses it's value in the sense of a '3D printed' 3D printer (do you see my point there? It's more about the message). Secondly, the fact that he is invested in those machines so much, shows you a few things: He does not care about the cost of his design, as he publishes his design for free for you to make yourself, but he charges you the labour and time it takes to make the parts himself. Secondly, he cares more about positively proving to everyone, "yes you can do this, if you have a design you truly care about, look, this is what I did, and here, if you would like some help to make your design, I'm happy to help :)", not in a malicious sense, but in a friendly and encouraging way. Injection moulding has an association stereotypically consisting of China, cheap quality, quick to break, bad colouring, replaceable, 'throw-away'... however 3D printed parts and products have a different association, stereotypically consisting of modern, *the word that describes a lot of time has been invested into something *, skilled, personal, well-thought out, well designed... We as a world have given these labels, and so Josef sees that if his parts are all 3D printed, the community knows that they have been a part of his journey to help create the new form of manufacturing we have been seeing since the 00s. So I don't believe he's idiotic for 'wasting money' on his chosen manufacturing method. There's a lead time on most products you buy new today, that's why you either make it yourself or buy it 2nd hand; like cars (I think lead time of 2 years for Tesla? Not sure on that). Feel free to critique my perspective, but as a design engineer (what an oxymoron amirite?), I feel it's important to analyse all factors from beginning to end to truly see the reasons why one takes decisions they take. :)

    I think Prusa is a great company that makes great 3D printers. I was fractions of a millimeter from purchasing an MK3 when I ultimately decided to go with an Voron 2.4 - not at all due to the printer's ability, but my desire to get a CoreXY system (an architectural choice as it were.) It is highly likely I will still get a Prusa printer for smaller print jobs in the future because it is just so reliable and easy to set up a print on. Great interview!

    Great to hear from Prusa direct what their thinking is about their printers and their value proposition. I'm new to the 3D printing scene, looking for my first printer. I'm seriously considering a Mk4, having gone full circle from thinking of getting a Prusa Mini Plus to looking at the Bambu Labs P1P and being seduced by their speed and value for a core xy machine (but not their cloud-based print servers, nor their fast growth-related production and customer service problems). I've come round to valuing the reliability that Josef Prusa spoke about as worth paying for. HOWEVER, it would be nice if the doubled productivity they expect from their print farm was passed on to customers in the form of lower prices... I seriously worry that their prices are becoming uncompetitive in the face of the new core xy machines coming out now - and especially Bambu seems a real threat to their long term core Prusa market. Personally, I've decided that quality, sustainable manufacturing and open source development and transparency are all things that I value and so I should put my money where my mouth is. But not everyone can afford that, and therein lies the danger for Prusa.

    The new MK4 is looking like a great set of improvements. I hope to get close to one and give it a run some time!
    We just pushed new Cartesian fixed-time motion planning with advanced Input Shaping to Marlin bugfix-2.1.x - which includes resonance variance based on Z height. This implementation was contributed by Ulendo for the open source world to use freely, and Prusa Research is certainly welcome to adapt it to their own firmware, which is based on Marlin 1.1.x. The fixed-time motion planning system itself replaces Marlin's just-in-time motion planning, but allows for switching to either motion system with a G-code (M493). As a separate motion system it has its own Linear Pressure Advance as well. (Ulendo is most famous for Filtered B-Spline -FBS- but this is not included in their open source contribution.)

    This looks like a solid printer, that takes us one step closer to one click 3d printing where you can set it and forget. And yes that means a focus on reliability and repeatability while maintaining quality over outright speed, so for many this printer will make a lot of sense.

      The development of printing was indeed initially due to Prusa and that is why it is disappointing that it has fallen so far behind.
      There are now communities and printers that are ahead of it (Voron, Ratrig, EVA etc.)
      And Bambulab's innovation has also raised the bar considerably. It offers more at a lower cost.

      when I was talking about open source I wasn’t just referring to Prusa there were lots of others as well, and a lot of the innovations were only possible after patents held by stratasys expired, now we have all these companies ditching open source, patenting stuff and once again potentially hamstringing consumer 3d printing.
      I would also argue that they aren’t behind, the mk4 is right on par feature wise, I am sure they would like to have bought it to market earlier but that’s just the supply chain reality right now.
      Bamboo might offer more for less but right now it’s realisability is an unknown, as is it’s long term customer and product support. Another factor that has to be considered when assessing value.

      I started with an Ender 3v2 in March of this year. I did a handful of the common mods for it and it was really just an entry point to kind of grasp the process of modeling and printing my own parts. I bought the Bambu P1S last month and the degree of separation between the two in terms of speed and quality is gargantuan. I mention this because I had considered moving to a Prusa mk3, however the hard fact is that the "bed slinger" as a design concept is inferior to "core XY" in its basic premise. Moving the mass of a print bed will always be a setback. However, Bambu does not have the track record of Prusa, and I would likely recommend a Prusa to someone who was looking to make money with their prints.

    I’ve been a loyal Prusa supporter/ customer for over 8 years. 10- Mk s. Few minis. I really like the nextruder concept and some other features. 4 mo ago I purchased a X1 Carbon ( with AMS ) since then I replaced all of my Prusas with X1 Carbon s and P1P s. Surprisingly after literally thousands of hours in total I’ve had zero issues that were the printers fault. The ams system works great ( you have to learn what spools / adapters work and don’t work). A couple years ago I bought an mmu2 and I could never get it working properly. Prusa says that they’ve put tons of testing into the mk4 , and I believe them because they have the man power and resources to do so. My only concern is I hope new printer was not rushed to market . To compete with the obvious Bambu Labs market. I’m a little disappointed it looks so similar to the mk3 , with not enclosure and no multi media. Speed is a big deal to me ,as long as the resolution of the print is not effected. The Bambu lab P1p and X1 both perform to another level. I understand the whole open source Prusa promotes and I get it , but there are quite a few aftermarket Bambu parts already to market. Im still rooting for Prusa, they are a great company. I think they relied on brand recognition until another company released a printer that blew there’s away. The XL was a interesting concept I’m assuming more geared towards industrial use due to the pricing . The long long long wait time turned many customers away. I’m hoping this works out.

    I like it. I mean, no more Z level adjusting, the printer does it. Speed much more than doubled, potentially. If I hadn't already gotten a Revo, the nozzle system would probably wow me more, but it's a nice system utilizing the older style part. Still need tools, but not a lot of them, so that's progress. The drive gear etc looks great and super reliable. Motors are more precise, so prints should be smoother. All in all, a great evolution of the MK3. Probably the best printer on the market if all you want is a machine that will work when you get it home and reliably print you whatever you tell it to print, without any modifications required.

You can get these on prusa (and some will be "coming soon" like the multi-material), but it would end up costing more with less functionality. I still holding off till the carbon 2 comes out to fix any problems that so far as I can see are few. And it will be cheaper hopefully.

    I appreciate that the new heater block design takes a page from the E3D Volcano. Hot-tightening the old V6 _and_ worrying about where to grasp the 200+ degree heater block so I don't break wires was not fun, and it's why I ended up with a leaky block and later an upgrade to a Revo hotend. It would be super nice if either Prusa or E3D come up with an adapter to Revo nozzle-breaks and hotends, but given the different location and size of the threads, I would be fine with just using the stock system and the V6 adapter.
    As someone who has 3 printers with touchscreens... PLEASE DO NOT USE A TOUCH SCREEN.
    If there's expansion capability for the mainboard, might I suggest things like a camera input and a few headers for things like LEDs?
    Even though a couple of the printers in the office are cloud-only, I kinda want to see a Prusa solution where you install the management software for Prusa Connect on a server in the office, then that manages the printer fleet connected on the LAN.

The problem is that it's very close in pricing to the Bambu printers which offer an enclosure, all metal parts, the lidar based auto calibration, and some more. What makes me still consider the Prusa is the sound difference and the better part compatibility. The Bambu seems very loud to be used in an apartment, though it finishes much quicker that's true. Also I wonder if they managed to stabilize the MMU3, because if it's not much better than MMU2 then the Bambu AMS is ahead again this regard.

    Nice video man, really cool to see them talk about it and seem excited. I am not a Prusa fanboi as I think they are just overpriced for what they are but I really like the new leveling system they showed and they are mostly reliable! I still think this was made as a stop-gap because of the XL having so many delays and problems they wanted to make people see they are still working on projects and not giving up. I started laughing as the little jab he made about the 3d printer landscape would be a different ballgame if all the manufacturers used their own printers to print their printers parts :) He is right about that.
    I used to work in an injection molding plant and from a cost standpoint they can be more cost effective when you have a FINAL design AND you are going to run that part millions of times. Machines are expensive, molds are expensive, maintenance is expensive but the pellets are cheap. I would love to see Prusa tackle the pellet feeders for 3d printers but I imagine the cost of the machine would outweigh the savings on plastic.

    6:37 As for input shaping, I'm extremely skeptical and it seems to me that they put that in on short notice. Unfortunately, you can't calibrate input shaping in general, as you want people to know in the video, because it varies from printer to printer, depends on the current belt tension and the location of the printer. Especially since the mass of the Y-axis changes constantly with a bed slinger.
    And because Prusa doesn't send an acceleration sensor with the printer, it unfortunately makes the impression that they only decided to include it shortly before the release. I would be glad if someone could explain to me exactly how Prusa wants to implement this with Input Shaping.

      The variation from one printer to another should be close to zero if you don't change the moving parts. The belt tension can vary but the printer can estimate it by measuring the current passing in the motors, this is already on the MK3. So I imagine that the input shaping can be tuned automatically with these values. And there is an accelerometer port on the bord for advanced users to calibrate more precisely their printers

    Upgrade cost is rather high though considering that you almost getting whole new printer. I don't use my printer that much to motivate the upgrade, but i will consider it or just get a new printer as a kit and sell my old one. Considering the cost of upgrade or new kit it might be motivated to get an SLA printer instead when Prusa releases an 8K version of it.

    There HAS to be a limiting speed for 'bed slinger' type printers that have to move a heavy print object on the bed. For small parts, these speed up technologies are great, but for larger objects, no "i3" style 'bed slinger' will ever print as fast as a 'core -xy' style printer with the bed only moving in the Z direction.

      @@Neo1983m No argument there! However Prusa did claim BOTH increased reliability and speed with this new model. All I'm saying is that they may have reached the limit of speed improvement with their 'I3' style printers, but no doubt will continue to improve their reliability. Still, if you need faster prints, you may have to run more printers in parallel rather than get faster printers. Which is why I still maintain that LARGE SCALE production should abandon 3D printing and use injection molded parts. Where that crossover point in scale is, depends on what you are making.

    32:56 I believe that a substantial amount of users HAS an MMU. Seeing how reliable the thing is and what a hassle it can be I doubt that so many people are practically using it. While the MK3S has been quite reliable for me (except for the LCD display being unreadable due to discoloring), the MMU has never worked reliably. It's a great idea but it the implementation is very poor... I hope the MMU3 makes it much better because it's not even close to the quality of the MK3S

    • @barrag3463
      @barrag3463 Рік тому

      From my experience the new filament sensor on the Extruder should finally fix things. For me, working with 3 different machines and 3 different MMU2s, there are 3 (to 4) consisten failure point to them, 2 (and the fourth one) being easily fixable.
      1) Point one was the selector sensor- sometimes strings of filament could jam the ball bearing. This could be fixed theoretically through better ram settings and sensor calibration but the permanent fix is just printing a new selector with a 2mm magnet slot below the filament path.
      2) Point two was the tube, which in it's default form had too tight of an ID, resulting in some ball-ends being too difficult for the motor to extract when unloading. This is fixed with a 2mm ID PTFE tube, as slop in the tube isn't really an issue on an MMU2 as the Prusa is still direct drive.
      3) the Third point was the unfixable one, which was the IR filament sensor in that stupid chimney. It needs recalibration basically after every other print as the chimney is eventually flexed out of position by the bowden tube, being secured by only a single screw, and it almost always would do this sometime into the print when you would be off doing something else. Since the Mk4 uses a spring-loaded ball and hall effect sensor inside of the extruder instead of an IR-chimney on top, I'm 80-90% sure that issue will have been fixed now.
      (the fourth point relates to multi-material prints, specifically PLA and soluable BVOH. Towers would sometimes delaminate and fall apart, which actually wouldn't often make prints fail somehow, but was obviously not ideal. This was solved by simply putting the transition tower inside a solid PLA object that was a little larger, which was jank but did work).
      Two way coms between the MMU and the machine itself will also help make errors more understandable, instead of the Mk3 only being able to tell you that the MMU is throwing a fit, and you having to look up the light pattern the MMU is flashing at you.
      I'll still wait but hearing that the filament sensor was changed on the machine itself makes me pretty hopeful. I just hope they incorporated the other improvements I listed out too, though they were more fixable for a regular person.

      ​@@dggcreations everything outside of actual toolchangers have some issue or drawback, really. Single Hotend setups will have issues of purging and load-unload, but multi hotend setups tend to more usually be direct drive meaning they're heavier (idk why that is, back in 2014 the ones I saw were mostly Bowden, but that was back in the early days of consumer printers).
      I don't think Single Hotend Multiple Extruder set ups are all that bad, issues with them mostly have to do with loading and unloading. Personally the easiest time I've had was a Neptune 2D, after inserting a correctly sized liner (they put in one that was too short) and switching it to PrusaSlicer which is better set up for SHME set ups, and I've converted a Multi-hotend Multi Extruder printer to the same kind of set up. The main difference is that with these SHME setups things are much simpler, the filament is simply parked by it's own extruder motor in a bowden tube 20ish mm from a 2-way splitter. Compare this to the MMU2 and the AMS, which are separate addons that have to "hand-off" the filament to the printer itself, meaning that, at least in the case of the MMU2 (I've not had the pleasure to work with the Bamboos or an AMS), the machine doesn't actually have any way to fully utilize the MMU2S, just ask it to load and unload, without even really having an idea what was going on with the MMU2S. On the MMU2S this was exacerbated, like I said above, by poor sensor design on the extruder. On the AMS from what I gather things are similar, with issues relating to spools not being able to be tensioned or parked correctly (from what little I know on the AMS' operation).
      By the nature of the Addons being Addons, the introduction of "handing off" the filament adds a point of failure. One thing I wish I could work with is the MMU1, which essentially does a similar thing to the Neptune 2D in that different filaments have their own extruder motor, and all are fed through a 4-way splitter into the hotend. It makes me wonder why they switched from that to the MMU2S; if I had to guess, maybe having a companion board for the four motors was as hard to implement as the MMU2's buddy board. I guess though my main point is that the SHME set ups work better if the printer is designed that way to begin with.
      I also agree on the Palette also. Working with the Palette 2 specifically, sometimes different filaments of the same type didn't play along well, and for what we were doing (PLA+BVOH support interfaces) it just didn't work. It tries to get around the "handoff" problem by splicing everything into one filament, getting rid of the load-unload issue, but makes everything more complicated by introducing a 3rd machine (the pi, and an underpowered pi at that) and having 0 recourse for you if the filament broke (at least with an MMU2 load failure it is possibly recoverable- just make sure you use a heatgun or blowdryer to heat the top layer of the print quickly and carefully).

    Actually quite interested in the mk3 to mk4 upgrade path. I own two Prusa MK3 printers (A launch MK3 upgraded to S+ and a purchased MK3S+ years later) and they are going strong, but funny enough I find my MK3S+ I bought doesn't print as well as I want (weird artifacts when the printer gets near the top of the print Z range). Rather then selling it and buying a new printer the MK4 upgrade may be perfect for it, and really not too expensive for what one gets as I was thinking most of the replaced parts are causing the issue. I can save the parts for my original MK3 (which is a rock solid workhorse) and experiment with my second one, but also staying in the Prusa ecosystem.
