Great interview Tom, big thanks to both you and Josef. Josef is spot on that having an idea is easy, making it work is the difficult part, but he has done it ... and keeps doing it.
My new i3 mk3 should be shipped in a few weeks. I gained confidence ordering one based on interviews like this one. J Prusa is the type of person it takes to make a great company. His close personal involvement, leadership, innovation and concern over quality are inspiring. I initiated a web chat last night on Prusa's website and received a reply very quickly. Try that with his competitors to see the difference.Thanks for the excellent interview Tom.
There is still tons of work to do on hardware as well. * Closed loop (can be cheap) * DC motors: for high power, high speed applications, can be done cheaper than steppers with closed loop control * general speed enhancements: New printers today are as slow or slower than those 3 years ago. 60-150mm/s? Let's move the decimal marker * Automation: Printing same object again and again autonomously (still requires hacking to be done) * Counter acting weak or poor build materials: Auto bed leveling with mesh already does this with Z axis, add the same for X and Y. Enables really long axles built on cheap materials. Imagine a garage printer capable of 2M by 2M by 2M volume without exponential cost increase, projects that scale may not necessarily need sub-millimeter precision to begin with ... * Getting to nozzle sizes 0.15mm or below reliable. Smaller the better * Direct pellet extrusion hotends within sensible weight and part budget Just to name few ideas people have been toying with, and some even used on production scale (automation by E3D guys). Infact, there is a TON of work to do, there's been research comparing 3d printing vs. injection molding, many above things would go a big way making small production batch (say 10k units) more sensible as 3d printing rather than injection molded. Sprinkle some coding in there, and one could build a business around one off custom tailored parts on customer specifications, in a way which scales and thus is affordable for the customer. Just to name an example

Hey, I did not say Josef had to have invented the Y splitting device when I mentioned the "flux capacitor" on thingiverse. I applaud Prusa for making it real and selling it, I am a fan of his work. On the occasion, I just meant to say that there was prior work on it.
+Vanillaessence96 So it would be better for this idea to never see widespread adoption? As far as I know it was not patented and copyright does not apply to non artistic works. Is it anymore stolen than the Arduino board that runs the printer?
So next time, when you use Pitagora's formulae don't say: "This is the Pitagora's formulae". Just say: "Look I can use this formulae". Do you find fair to don't mention the project? This is not Open Source style, come on. I'm sad. Again, this multiextrusion method is used and sold since 2015.
+G0rdTheR0gue these projects are built on countless open source ideas. Would Joe need to list them all when interviewed about anything. He provides attribution in his blog where he first showed the world and I suspect all the details will be amongst the open source files for this printer. And bear in mind that there is no legal obligation to do this. Complaints like this just seems like small minded people wanting to have a go at one of the few people who have managed to turn open source into a successful business while providing jobs for 60 other people. There is NO issue here, quit moaning.
Scienteer Moaning? Ahahah I'm just saying that is sad hearing "ideas without good execution are worthless". The good execution was there (4 ways multiextrusion) one year before Josef, 2 ways multiextrusion was there two years before Josef. It's a fact that Josef based his project on the perfect working kit Flux Capacitor (Flusso Canalizzatore). so instead of saying "ideas without good execution are worthless" why not "I based my multiextrusion system on the Flusso Canalizzatore". Making reference to it's the heart of the Open Source, come on.
It's dudes like you, Tom and James Briton that inspired me to try designing and building my own CoreXY design. I completely agree with Josef about how the execution of an idea is more important and formative than the idea, especially in open source.
Two of the scene's greatest guys talking... :-) I hope Josef puts the i3 MK2 printers, he took to the fair, back to the parts printing farm, asap!!! I'm waiting for my i3 MK2 order to be processed... -.- :-D
Absolutely. Just like that little computer company that started out in a garage. People are constantly saying Apple wasn’t the first to do this or that.But the company is the best and the one that got it right.
Nice work, Josef and co.! I'm in the process of integrating the lower-level MK2 branch changes into Marlin 1.1.0-RCBugFix, starting with the planner acceleration / max_jerk adjustments. I've been overhauling the bed leveling functions lately, and finally got automated "bilinear" leveling (formerly limited only to Delta) working on cartesians. It isn't exactly the "la grange" method, AFAIK, but it's essentially the same as Ernesto's "Mesh Bed Leveling," and it does produce a decent curvature and in testing it helps a lot on a big uneven surface. I'm thinking about automating the "mesh" bed leveling next, which should be fairly straightforward. But first, I have a stupid probe-movement bug to chase down. Always something…!
Should do a video on best way to make multi-color models in a variety of methods. Obviously you could discuss the simple ones like creating separate bodies in CAD, but doing something more complex like coloring the eyes of an existing figurine STL would be great!
Hey Tom! What's your information on the availability of the firmware and controls the MK2 uses for the multiplexing board? I was thinking about installing a similar system into my own printer (a normal Prusa i3 from some E-Bay account, RAMPS 1.4), but that'd only work if Prusa Research integrates their software approach into some common firmware, like Marlin. What they do is truly awesome, and I really hope that they share this for everyone by not just constricting firmware and other things to their exact specs, but time still has to come to show if they will share, or keep to themselves.
Hey Tom, Was wondering what you think was implemented better for the multi-filament printing, the Prusa or the Prometheus? Both seem to have the same concept. Also great interview!
At the end of November, the Prusa Original i3 MK2 will have it's duel and quad upgrade available to buy. Around then, perhaps a bit before, we will start to see real world examples of how it all works and how well engineered it is.
"execution is everything" - he just nailed it. that's why patents suck. companies get ideas, patent them and then suck on the execution and nobody else can jump in and do it right. Open Source for the win!!!
It's just normal filament, it's always for sale. There's nothing new about the filament. Unless you're referring to a different printer. I'm not a super advanced user, so sorry if I'm misunderstanding. The quad-color upgrade for the mk2 is on preorder and the prusa site mentions it will be available by the end of November. Keeping in mind if it's super popular then it might take a few weeks to ship. :)
Colour is just scratching the surface. Using different filaments with different properties in different parts of the build where you would normally have to assemble (and design for assembly) means a whole new mind set in thinking how to design. You can save on material costs by putting more expensive higher strength materials where they are needed rather than making the whole build out of it. You only need to put the expensive material on the outer surface layer/s.
That's not strictly true. You could envisage a mechanism where the head parks somewhere and adjusts temperature before changing materials. It would lengthen printing time but it's feasible.
That would depend on how effective the pull operation is when retracting the previous material. If you could do the equivalent of a cold-pull then it could be workable. It may be difficult to achieve but maybe not impossible.
wait a second four materials....where the heck is the blend tower for this thing? it should require a tower of mixed filements as the hotend transitions between types but i dont see anything edit: wait nevermind i looked at their official video and yes, there is a waste tower
Prusa research is PART of the open source community. In fact, I have a home-built machine that is loosely based on the i3 (upright cartisian design, but with a different rail system) and I just ordered a Mk2 upgrade kit because I wanted the new heated bed and their easy bed leveling features. I've also pre-ordered the quad extruder kit. If you have a vuaguely i3 design, and use a RAMBo-mini control board, it should be a drop-in solution. Even if you don't have the Mk2 kit, or have a different control board, you should still be able to pull their multi-extruder code out of the downloadable version of Marlin and then splice it into your firmware. There isn't anything standing in your way if you want to try to cobble something together. That is the essence of open source.
The reason I asked this question is because allot of stuff has been copied lawfully or unlawfully by the Chinese manufacturers, which on one end of the spectrum they enable a low cost market and put these machines in the hands of many people who would otherwise not be able to get one. The downside is that it reduces profits for such a company. With that said as far as I am aware prusa has not yet released their actual auto leveling firmware source, this means they have some reservations on this. They have every right to not release it if they wish not to do so, I have no qualms about it either way. I was just curious.
Ok, now I see you that you mention that in the video description. It's somewhat hidden though. I didn't find it when I went to buy something at amazon last time, probably because it was an older video and I did not expect to find international links under the link you just posted.
In Open Source basically no one owns anything, so essentially no one should be seen as 'stealing' open source ideas. Prusa here is merely harnessing rough open source ideas and executed it to generate sales. Prusa isn't stealing anything, and he is properly attributing or not claiming that he 'invented' the idea for multimaterial prints. However... since all this open source is 'free', the Chinese will again copy everything Prusa has done now and will sell it for less than half whatever Prusa is asking for. And Prusa will again lose sales to the Chinese. Lost sales means lost revenue for Prusa and lost revenue means that eventually some of the 60 jobs created by Prusa will be under threat of layoffs - sooner or later (largely depending on how quickly the Chinese can up their quality). But that is not, by far, the biggest pitfall of Open Source. For a 'real' inventor with breakthrough ideas, why should he or she bother to create, develop AND execute the invention if ultimately he or she will not benefit from it, if others can freely copy his or her invention with impunity? The end result at the macro level is intellectual - and economic -stagnation, and a plethora of incremental improvements, but nothing really new or earth-shattering. The real purpose of the Patent system is to prevent that stagnation, by protecting inventors. Sadly this the Patent system's original intent is being undermined by old, incumbent corporations, greedy rich individuals, unscrupulous lawyers, corrupt judiciary and uber rich legislators. So, if you ever produce anything and offer it up as Open source, well think very carefully before you do - especially if you need to feed a family or pay salaries of your employees. I'm a big fan of Tom Sanladerer. Do please support him by using his links whenever you buy anything online. Which is what I do. Hopefully those links are up-to-date.
And a hotend that can blend them. But they already have 4 colors, so 1 extra should be doable. Then it's just the hot-end and the software/firmware :) If anyone can do it, it's Prusa!
From their site: Materials with vastly different print temperatures cannot be printed at the same time. But this is theoretical as printing ABS and PLA at the same time isn’t a good idea anyways because of vastly different heatbed temperatures. Small temperature changes can be done during printing the smart tower.
For hard filaments, the E3D hot end is pretty responsive going up, the problem is cooling back down to lower temp materials, the fan just ain't that quick. Flex filaments still a no go with this set up...
Too bad the multicolor system and the multiplexer has already been done at the end of 2014. This is a video where I show a card with a driver is a relay multiplexer which controls three extruders with a single driver. Everything is already existing and running in MarlinKimbra or MK4duo ... The multicolor system or flux capacitor of Immagina & Crea. Everything is open and explained in the forum reprap Italian. ua-cam.com/video/sz3edwkgiIA/v-deo.html github.com/MagoKimbra/MarlinKimbra www.thingiverse.com/thing:498922 forums.reprap.org/read.php?362,474553
Prusa: no patent existed, so we took it, overcharged for it, I never finished university, my parents paid for my company Sounds like making money off open source is good business.
You kind of forget how crucial Josef's designs were in the early days of RepRap.... What are you thinking about when you say overcharged for it? The MMU1 was actually an almost too cheap upgrade, it would almost worth to just buy it for the parts...
Mike Jones that everybody is praising him for this innovation and he is bragging a lot for a work that is not his. He just copied Marlin Kimbra and the work that he saw in maker faire Rome 2015
All of this stuff is open source and he himself said the idea isn't what matters it's the execution. No one is preventing anyone from making a new printer and doing all the same shit he's doing in it and even improve on it. That's the whole fucking point of the RepRap movement.
You do realize that the most commonly copied printer on the market is his design, right? As far as his "innovation" is concerned, his achievement here is in the execution. Who else has put together a system like this, that is this plug-and-play? It's not like he's above criticism, but I really don't see why people are acting like Prusa is the new MakerBot...
Great interview Tom, big thanks to both you and Josef.

No patent = you can't sue me, and I can make money off others designs. Sounds legit
Two of the scene's greatest guys talking... :-)
I hope Josef puts the i3 MK2 printers, he took to the fair, back to the parts printing farm, asap!!! I'm waiting for my i3 MK2 order to be processed... -.-
:-D
he is right, anyone who says that prusa are taking ideas are being stupid, an idea is only an idea, the difference is following through with it
Absolutely. Just like that little computer company that started out in a garage. People are constantly saying Apple wasn’t the first to do this or that.But the company is the best and the one that got it right.
BigTrainBuff apple sucks. Xerox did it first, learn your history. Prusa is over priced.

I would love for them to make a couple bigger options.
Newton's second law suck for 3D printers...
I'm hoping for a Prusa Delta :p
I'd like a smaller frame printer, actually. I would be interested to see Prusa's take on that.
If anyone can, Prusa can. I'd love to see it.
smokeydops Love to take the printer around too :D
Should do a video on best way to make multi-color models in a variety of methods. Obviously you could discuss the simple ones like creating separate bodies in CAD, but doing something more complex like coloring the eyes of an existing figurine STL would be great!
I clearly see whats gonna be my own little christmas gift this year... !

Czech and German chitchatting in english, sounds like a star of a good joke :-D
Thanks Thomas :)
Looking forward to your thoughts on the system once you can get your hands on it and test it.
Like always amazing video! I agree they didn't invent they make it work!
HEY BROZ - CAN I ACTUALLY STICK AND MK2 IN TO A LATEST BIGGEST PRUSA PRINTERS LIKA i3 300x300x420mm ???
Hey Tom, Was wondering what you think was implemented better for the multi-filament printing, the Prusa or the Prometheus? Both seem to have the same concept.

Disappointed to hear that he won't make the multi color a full assembled kit! I would pay 1,200+ to have it all come to me ready to go out of the box!
I would like to see the feeds controlled to give true colour mixing much like an ink jet but through only one nozzle.
Hi, I work with this system from 1 year, isn't news, three italian guys invented on 2014
Hey Tom, any word on when the Quad filament will be available for sale??
It's just normal filament, it's always for sale. There's nothing new about the filament. Unless you're referring to a different printer.

Awesome interview. One question I have is, will the multiplexer be available to the open source community?

Bruno, the Marlin firmware including Auto Mesh Bed Leveling has always been on GitHub: github.com/prusa3d/Prusa-Firmware/commits/MK2
Amazon US link doesn't take me to a product page, does it matter to you Tom?
Does it work for other domains as well, e.g. if I replace the .com with .de?
Ok, now I see you that you mention that in the video description. It's somewhat hidden though. I didn't find it when I went to buy something at amazon last time, probably because it was an older video and I did not expect to find international links under the link you just posted.
I wonder if they are going to make another version of this printer with an even larger build volume...?
I wish I had a Prusa...

next CMYK color mix 3d printer ... next next next 3D printing in the air
Next step: color blending :)
It would need 5 colours to get a reasonable range of colours, white, black and three primaries.
That sounds really difficult.
And a hotend that can blend them. But they already have 4 colors, so 1 extra should be doable. Then it's just the hot-end and the software/firmware :) If anyone can do it, it's Prusa!
Two great genius
Damn, you soon reach 40k subs...
First! Question: Is it possible to print matierials with different printing temperatures with this setup?
From their site:
Materials with vastly different print temperatures cannot be printed at the same time. But this is theoretical as printing ABS and PLA at the same time isn’t a good idea anyways because of vastly different heatbed temperatures. Small temperature changes can be done during printing the smart tower.
Yeah that's what I thought. Makes sense. Thanks for looking it up and letting me know.
For hard filaments, the E3D hot end is pretty responsive going up, the problem is cooling back down to lower temp materials, the fan just ain't that quick. Flex filaments still a no go with this set up...
best value printer no doubt...
2:42 WTF! Link to thingi please! :)
It's not a free model, it's a company creating 3D rc plane models, but you have to pay for them.

The Apple of 3D printing.
I think MakerBot deserves that title more.
More like the android of 3D printing
Prusa: no patent existed, so we took it, overcharged for it, I never finished university, my parents paid for my company
Sounds like making money off open source is good business.
You kind of forget how crucial Josef's designs were in the early days of RepRap.... What are you thinking about when you say overcharged for it? The MMU1 was actually an almost too cheap upgrade, it would almost worth to just buy it for the parts...
again, he didn't invent anything about this kind of multiple extrusion
And Henry Ford didn't invent the automobile. So what's your point?
Mike Jones that everybody is praising him for this innovation and he is bragging a lot for a work that is not his. He just copied Marlin Kimbra and the work that he saw in maker faire Rome 2015
All of this stuff is open source and he himself said the idea isn't what matters it's the execution. No one is preventing anyone from making a new printer and doing all the same shit he's doing in it and even improve on it. That's the whole fucking point of the RepRap movement.
You do realize that the most commonly copied printer on the market is his design, right?
As far as his "innovation" is concerned, his achievement here is in the execution. Who else has put together a system like this, that is this plug-and-play?
It's not like he's above criticism, but I really don't see why people are acting like Prusa is the new MakerBot...
Mike Jones creality is poised to stop Prusa. Price alone.
Small loan of million dollars.
Tom, your intro really doesn't sound like English at all. speak slower.
