I love that you both actually show stuff like skipped step detection and filament run out. So confident in this amazing machine. Cannot wait to own one!
I love the simplified cabling with doing away with endstops. The filament sensor is awesome - very well implemented. Bed leveling and resume after power loss are done right as well. Bumb and skip detection is way cool. Love to get one of these!
Superb interview Tom, thank you. Sorry I missed you at TCT. The MK3 is an awesome machine, I'm glad Joe isn't afraid to increase the price a little. The race to the bottom should never be a focus. Huge appreciation to Joe and his team for bringing us the MK3. Even though my MK2 is still a fantastic machine, I'm still eager to get my hands on the MK3 and all it's new features.
Such a great interview. I watched this when I first got into 3d printing. I just re-watched it. It makes sooo much more sense now. Thanks for the video Thomas! I think I found my next 3d printer.
One of the core enablers for the MK3 are Trinamic's stepper motor drivers - check them out here www.trinamic.com/solutions/manufacturing/3d-printing/ [sponsored link] Also, here's the second part of the Interview, focusing specifically on the new Einsy mainboard 🤓 ua-cam.com/users/edit?o=U&video_id=RuvaSTg33r4 What do you think about the new MK3? Is the MK2 or other printers already "good enough" or are the new features from the MK3 worth an upgrade for you?
Personally, I think the upgrades are great. I love the removable bed, and I like that it is more robust in what it's able to sense and detect. I think that features like this are needed in order to bring 3d printing to a larger audience.
You should upgrade for the Trinamic's stepper motor drivers alone. I have a Duet Wifi 32 bit and it is a night and day differance ,your motors run much more silent and cooler then whatever other onboard stepperdrivers i had in the past.
Interesting to hear from Josef that a MK3 upgrade MIGHT happen in the future, i personally would consider it if they release a MK2.5 to MK3 upgrade in a years time or so, the main reason being upgrades AFTER MK3, i.e. MK3S/MK4 etc. Depending on the economy of it all though, selling the MK2.5 and buying a MK3 might be a better way to go.
I won't be upgrading, but I'll definitely see how much I can steal from them on the machine I'm designing. (which I probably won't finish for another 20 years, but that's engineering without being an engineer)
man, I want one so badly, such an awesome piece of machinery! (Awesome work Prusa Team!). I'm currently building my own coreXY system but having to set everything up yourself is a lot of work. I'm not gonna lie, part of me wants to just buy one of these and be happy.
I would love to see a live assembly in toms workshop with Josef coming by and constantly reminding Tom to rtfm. Honestly you both were super entertaining in these interviews. Saw them twice now:-)
Wow, I wonder how much of this will be turned into aftermarket sensor kit mods, with some clever firmware hacks ! That was a pretty impressive list of adds, from a legendary builder, and Tom's "full stack engineer" knowledge base; very exciting !
I love all the MK3 videos coming out, but what I haven't seen yet is a SPEED TEST!! Come on, guys! Prusa claims it will do 200+mm/s out of box, that's a big claim to make, and footage that people definitely want to see.
Almost feels like the mk3 is not so much a new printer but rather a fancier tier. It's the one with the powered windows instead of the crank windows if you know what I mean.
I've wanted to upgrade my Printrbots to 24v electronics for sometime now, can't wait to see the BOM! Great interview as always! Now, let's see a tour of Prusa's bot farm!
Another brilliant piece of engineering from a man that just keeps raising the bar. I can't wait for the release of improvements just to study and learn from and incorporate into my own machines. I've built most of my machines from scratch but if I were to buy a pre-built printer this would be the one. Almost any single one of the improvements is worth $50 and when you put them all together it's really a ridiculous bargain ..... Anyone that does a lot of daily printing has likely lost more than $50 in time and filament because you can't recover from many errors .... Now you can Now excuse me, I have to drum up more business so I can justify another printer and buying one of these .......
wow! looks like a great machine -but did anyone else noticed "missing lines" in both of the shown printers in some layers of the figurine, which was printing (bunny?) - anyways, seemd to me, there were extrusion flawws, where part of a louter layer was missing , that is very unfortunate, especially on a larger and longer lasting print, since such defects are so visible to the eye...
+kniefi I've noticed them, too, and decided to leave them shots of the flawed print in there. It's probably due to the printer getting bumped or the extruder runout feature being shown off a bit too often, but it's something to keep an eye out for with the retail units (remember, these are technically "beta" printers)
I'm so excited for the future of 3D printing! I own Anet A8, which is amazing for the price, considering only few years ago it was impossible for a normal person to buy any 3D printer! I wonder when people will have them as widely available as normal printers now :D
I own an Anet A8 but have been thinking of getting a second printer (and a "fancy" one), and I think the Mk3 will be the one. I can take my Anet A8 and build a metal frame for it and slowly upgrade it while the Mk3 becomes the workhorse I can leave on while at work with far less worry about failed prints and fires (and yes I did upgrade my Anet A8 to lower that threat, but it not the same).
Filament and model designing are the bottlenecks it seems. There is a lot of focus on teaching young kids to design simple things for 3d printing so if filament quality, control, and availability improves then we are all set for having 3d printers in "every" home in just 1 generation.
Great interviews! Love hearing details about MK3! Going igus would be great: no more grease. No more rattle. No more „where does that ball come from?!“
Josef Prusa and x and y should be quite parallel per design on the MK3? Y especially in comparison to MK2S. Hm and z is also constrained by the frame and printed parts. Is parallel the issue getting the igus smooth?
What is the best printer for newbies first printer? Should I buy cheap Anet or Monoprice select mini or should I go straight to Prusa i3 MK3 (MK2/S) or Ultimaker 2 or Zortrax M200 or similar? Which one is the easiest way to quality 3D prints?
Hi Thomas. I have had three 3D printers, Hictop, Geeetech and a Lulzbot Taz 5. The Lulzbot was a used machine which never delivered consistent results, it was average at best. I’m considering buying the new Prusa MK3. Being a more modern machine and a genuine i3 do you think this is a good decision or would I be better of getting the CR-10?
I was wondering about 12:17 min...Isn't there a more elegant way to remove that bit of filament? I am always afraid not to be fast enough after color change :D Can you actually make something like a mini wipe tower?
i was just on their site and and looks like they have 2 kits for MK2/Mk2s the full upgrade to the MK3 and the half upgrade to MK2.5 you should do a video that show cases them
Will Prusa consider developing a 300mm x 300mm PEI plate for general use? I'm building a printer with Prusa multi-color upgrade kit and the Mini-Rambo and I would love to have this plate for my build.
Hey Thomas, how about a video on fan controllers in 3d printers? I have two 40mm 24v fans spliced together on my wanhao Duplicator 6. Trying to figure out how to reduce their speed / noise.
Really enjoyed this interview, well done! Is there any word on multimaterial support for the mk3, and (more important for me) if there will be an upgrade kit from the Mk2 MMU to the Mk3 MMU? I presume the MMU will have a filament sensor in each of the extruders, for example.
Yes will be a modified MMU kit for the Mk3 which will include the additional filament sensors. Will be available shortly after the Mk3 begins shipping. Thinking about adjusting my order so they ship separately, not sure I want to wait until both are available to ship.
What are the print imperfections s that look like a bunch of missed layers when he speaks of the sensor induction having a thermistor. Around 5 mins or so.
Unfortunately not. Filament has become much more consistent over the years, so a diameter sensor is something that certainly exists, but keeps dropping lower on everyone's priorities.
The cables are pretty well protected with this cable management system, especially since the small change they did on the extruder cables with the update from MK2 to MK2S. Drag chains would only add cost and complexity, and there is actually more strain on the cables inside a drag chain, where they are constantly bent back and forth. This setup is better in this regard as the cables are supported by a piece of 3mm nylon filament. That means the cables can move around as they have to, but they will never be bent in a tight radius.
I print PET on PEI all the time even on mk2. It does stick a bit too well, but nothing crazy. Try using a super duper think layer of glustick to create a separation layer or just touch the bed with fingers to lower adhesion a little bit.
I made the mistake of printing PETG on clean PEI once and would never do that again. It kinda fused together, so I don't think it would pop off an untreated flexible PEI bed without damaging the flex bed first (at least for bigger printed parts). I always wipe the PEI bed on my MK2S with window cleaner before printing PETG and it works.
Good question! I'm betting not (yet), but with the right filament sensor, it' would totally be possible. All you would need is to be able to continuously measure the diameter and you'd be able to calculate it in real-time. Brilliant idea! PS. Great interview. Thank you Thomas and Josef!
I have the Prusa i3 MK3S and when I cut the filament, it jams and I have to take it out with pliers! It does not spit it out like the demonstration in this video. Also whenever there is a filament jam, the 3D printer does not sense it! What am I missing! ? anyone else having the same issue?
I don't quite understand the how they are getting higher microstep resolution. Josef mentioned that they are using 16 microstep instead of 256 which the driver is capable of... but they are still getting good resolution some how? I'm confused.
It's the Trinamic motor driver IC that receives 16-step step/dir inputs like the old Allegro one; however it interpolates internally to 256 steps to drive the motors. Be aware that the electro-mechanics of the stepper motor is not entirely linear with microsteps, so more than 16 microsteps is really not sensible with regard to mechanical resolution; so whatever issues (probably 1/16th worth of step of latency) Trinamic might introduce don't result in worse positional accuracy, but it does result in smoother motion with less jolt at the bearings and lower noise level, and they are balanced out by multiple driver ICs having the same behaviour.
That doesn't improve the resolution at all... It only makes the motors quiet. The way interpolation works it splits a single move into multiple smaller ones, but the movement is still the same.
Very nice software features, but the hardware is still quite disappointing for this pricepoint. There are way too many 3D printed parts for some of the critical portions of the printer. Sure it works, but linear rods, bearings, and motors should not be mounted to plastic printed components in a printer of this cost!
Do you have a MK2? It prints tremendously and the quality is equal to an ultimaker. I agree that the printed parts at first looks like a cheap way to do it, but ditching that would destroy the whole philosophy of a rep rap self replicating printer. Users wouldn't be able to print replacement parts or modifications
"MK3 Prusa" alias "The unstoppable Prusa"... cut the filament, cut the power, bump in one of the axis... it will just continue "it's mission: to explore strange new opportunities, to boldly go where no one has gone before..." :)
Yes, it will be available a few weeks after the Mk3 begins shipping, I switched my Mk2s/MMU order over to the Mk3 including the updated MMU with extra filament detectors. Not sure you can preorder the ungraded MMU yet since they have not worked out the pricing difference.
William Dutcher not sure you well understand what I ask. I already have the mk2s upgraded with MMU and it works great. So my question is not about existing an mk3 MMU but if an upgrade kit from mk2s+MMU to an equivalent of mk2s 2.5 upgrade but with 4 filament detector per example.
Sorry, I did misread your question. While I can't speak for them, I think it would be a mistake for them not to support the MMU upgrade path. Just requires 3 additional sensors, cables, and 3d printed extruder enclosures. In fact they should allow the MMU upgrade path across the board even without doing the Mk2.5 upgrade. Since the MMU is much more sensitive to filament jamming issues. Hopefully they will see the logic in doing this.
Uuughhhhhh, that's it I'm burning the Chinese i3 clone I've spent hundreds of hours tuning and improving and getting one. Not sure how I'm gonna afford it but I'll find a way.
I love that you both actually show stuff like skipped step detection and filament run out. So confident in this amazing machine. Cannot wait to own one!
Ahaha the moment he talked about the clone... Great moment!
Great interview, Tom! It's looks like it was much more comfortable interview Jo indoors :)
Thanks! Certainly a great setup to film, but not without its own set of distractions 😉
#HIGHFIVE
haha, I see what you did there.. made me go look for your interview, well played sir!
I love the simplified cabling with doing away with endstops. The filament sensor is awesome - very well implemented. Bed leveling and resume after power loss are done right as well. Bumb and skip detection is way cool. Love to get one of these!
Hervorragendes Video. Das ist das inhaltlich mit Abstand beste Video das ich bisher gesehen habe zum MK3.
Literally three intentional failures during this video and not one failed print.
Incredible.
First interview I've seen of Mr. Prusa. Seems like a smart, calculated and sensible fellow. Open source FTW!!
Superb interview Tom, thank you. Sorry I missed you at TCT.
The MK3 is an awesome machine, I'm glad Joe isn't afraid to increase the price a little. The race to the bottom should never be a focus.

This is how interviews should be.
+Adrian Galilea thank you!
The best interviews are usually performed by people who are interested in the subject and the people they interview.
I must say he impressed me with all his answers on your questions. You can tell that he is an inteligent guy.
I suffered a power cut just yesterday and lost an almost finished print on my Anet A8. Great to see that problem being resolved.
One of the core enablers for the MK3 are Trinamic's stepper motor drivers - check them out here www.trinamic.com/solutions/manufacturing/3d-printing/ [sponsored link]

(which I probably won't finish for another 20 years, but that's engineering without being an engineer)
I upgraded my MK2 to the "S" version a few months ago and I really like the new features of the MK3. I'm planning on buying one early next year.
man, I want one so badly, such an awesome piece of machinery! (Awesome work Prusa Team!). I'm currently building my own coreXY system but having to set everything up yourself is a lot of work. I'm not gonna lie, part of me wants to just buy one of these and be happy.
I would love to see a live assembly in toms workshop with Josef coming by and constantly reminding Tom to rtfm.
Honestly you both were super entertaining in these interviews. Saw them twice now:-)
What is rtfm?
Wow, I wonder how much of this will be turned into aftermarket sensor kit mods, with some clever firmware hacks !
That was a pretty impressive list of adds, from a legendary builder, and Tom's "full stack engineer" knowledge base; very exciting !
I love all the MK3 videos coming out, but what I haven't seen yet is a SPEED TEST!!
Come on, guys! Prusa claims it will do 200+mm/s out of box, that's a big claim to make, and footage that people definitely want to see.
Almost feels like the mk3 is not so much a new printer but rather a fancier tier. It's the one with the powered windows instead of the crank windows if you know what I mean.
Nickelme whats wrong with that though? You cant really improve the print quality haha
Jozsef cracked me up... “i wonder why no one cloned the mark 2 one to one..... oooohhh....!!” 😂😂👍👍
Ps. Great interview!! Nice work Tom!!
Nicely done Tom. Your interviews are a breath of fresh air.
omg I'm so happy I bought an MK2 to fund this.
I've wanted to upgrade my Printrbots to 24v electronics for sometime now, can't wait to see the BOM! Great interview as always! Now, let's see a tour of Prusa's bot farm!
"And now should we do the electronics?" Haha I love the little behind the scenes end part XD
mk3 looks real proper. Let's dolly the shit out of it.
Geeking out right now, this is the sort of dude I hope to work for when I graduate.
Tom, this was a great video! I think that the upgrades definitely warrants the upgrade.
It was great to Josef at the TCT. Didn't see Thomas but then the place is so big...

I find 3d printers are already a more practical and reliable thing than standard printers. It's just getting them to be more ubiquitous and quieter.
Great interviews! Love hearing details about MK3!
Going igus would be great: no more grease. No more rattle. No more „where does that ball come from?!“
Considered igus, but they are much harder to get them running smooth :-/
Josef Prusa I believe that! I guess stall detection then kicks in as a false positive reaction?
Josef Prusa and x and y should be quite parallel per design on the MK3? Y especially in comparison to MK2S.
Hm and z is also constrained by the frame and printed parts.
Is parallel the issue getting the igus smooth?
I'm definitively buying a prusa the next time I buy a printer.
Will the new toolhead be compatible with the multi-material upgrade? If I can print in soluble supports, this will be the best printer available!
What is the best printer for newbies first printer? Should I buy cheap Anet or Monoprice select mini or should I go straight to Prusa i3 MK3 (MK2/S) or Ultimaker 2 or Zortrax M200 or similar? Which one is the easiest way to quality 3D prints?
Kannnattaa oikeesti ostaa Prusa mk2s tai mk3 aivan mahtavia printterejä!!
Hi Thomas. I have had three 3D printers, Hictop, Geeetech and a Lulzbot Taz 5. The Lulzbot was a used machine which never delivered consistent results, it was average at best. I’m considering buying the new Prusa MK3. Being a more modern machine and a genuine i3 do you think this is a good decision or would I be better of getting the CR-10?
i'm considering the same thing. i might just buy both to be sure.
Really looking forward to getting my hands on those PEI coated steel sheets for my Ultimaker.
Nice interview! Not afraid to ask the hard questions!
I was wondering about 12:17 min...Isn't there a more elegant way to remove that bit of filament? I am always afraid not to be fast enough after color change :D Can you actually make something like a mini wipe tower?
i was just on their site and and looks like they have 2 kits for MK2/Mk2s the full upgrade to the MK3 and the half upgrade to MK2.5 you should do a video that show cases them

The perfect farm machine!!!!! Awesome...
Well, thats kinda how we find out things to improve :-) Farm is 287 now!
Really enjoyed this interview, well done!
Is there any word on multimaterial support for the mk3, and (more important for me) if there will be an upgrade kit from the Mk2 MMU to the Mk3 MMU? I presume the MMU will have a filament sensor in each of the extruders, for example.
Yes will be a modified MMU kit for the Mk3 which will include the additional filament sensors. Will be available shortly after the Mk3 begins shipping. Thinking about adjusting my order so they ship separately, not sure I want to wait until both are available to ship.
Awesome improvements. Question now is when will Prusa make the foot print bigger?
9:20 that awkward moment when they confront you for something you have done
I'm worried about large abs prints pulling the spring steel from the bed.
They print solely ABS parts in their print farm. 140 printers iirc? My point is, they test everything rigorously before release.
what a great inteview very good questions :D
Excellent interview Thomas. Thanks.
i stinking need one of these. also...need to incorporate some of these features into my giant 3d printer
I always imagined Joseph Prusa as a old guy with grey hair. He looks hella fresh and sorta buff for a tech guy. Nice to be proven wrong lol.
Which should I get? 2.5 upgrade kit or 4 color multi material kit?
Amazing guy. He's on that bleeding edge...he keeps the innovations coming.
what the diference on time printing to i3MK to CR10?
The Prusa i3 sure has evolved over the years! fantastic
I wish they brought out an XL version with a bigger print bed. I’d be all over it like a rash!
What are the print imperfections s that look like a bunch of missed layers when he speaks of the sensor induction having a thermistor. Around 5 mins or so.
Why is it more suitable to run the system on 24V when using the TMC2130 drivers? What would be the problem otherwise?
Will the new optical sensor be able to determine filament diameter and adjust extrusion multiplier in real time? That would be a very nice feature.
Unfortunately not. Filament has become much more consistent over the years, so a diameter sensor is something that certainly exists, but keeps dropping lower on everyone's priorities.
Does the Prusa MK3 version of Marlin have support for other mechanics like Delta and CoreXY?
It would be good if they used the optical sensor to track movement to perform an automatic extruder steps/mm calibration
This looks incredible. Also, great interview. I was wondering if he was ever going to mention your mk2 clone.
Damn, that video quality is nice.
Have you gotten a chance to try and review one?
+Lon Varscsak soon... very soon
XD! that GULP! at 9:43
16:29 "the assembled one costs the same". prusa shop says 769€ / 906$ for the kit and 999€ / 1209$ for the assembled one.
I thought he meant the same as the assembled Mk2S
I hope they make a X or Elite version, that has the ruby and multicolor and carbon parts.
I miss small drag chains to get a better protection for the cables.
The cables are pretty well protected with this cable management system, especially since the small change they did on the extruder cables with the update from MK2 to MK2S.
Drag chains would only add cost and complexity, and there is actually more strain on the cables inside a drag chain, where they are constantly bent back and forth.
This setup is better in this regard as the cables are supported by a piece of 3mm nylon filament. That means the cables can move around as they have to, but they will never be bent in a tight radius.
You can print them :)
I think Tom got a little aroused talking to Josef, look at those sparkly eyes!
lol, engineer-wood, I get that too !
if you buy a 2.5 upgrade will that allow to buy the mk3 multi filament?
Its a shame no one will get a printer till December!
I see an i3 MK3 in my future... that's a printer worth waiting for!
How does the flexible PEI bed work with PET filament? Does the flexing make it possible to use PET on a PEI bed?
I print PET on PEI all the time even on mk2. It does stick a bit too well, but nothing crazy. Try using a super duper think layer of glustick to create a separation layer or just touch the bed with fingers to lower adhesion a little bit.
I made the mistake of printing PETG on clean PEI once and would never do that again. It kinda fused together, so I don't think it would pop off an untreated flexible PEI bed without damaging the flex bed first (at least for bigger printed parts).
I always wipe the PEI bed on my MK2S with window cleaner before printing PETG and it works.
Did he say US warehouse!? I wanna work there! Willing to relocate!
Couldn't you design a dual drive extruder with a built in mechanical switch?
Does the MK3 do auto flow rate calibration?
Good question! I'm betting not (yet), but with the right filament sensor, it' would totally be possible. All you would need is to be able to continuously measure the diameter and you'd be able to calculate it in real-time. Brilliant idea!
PS. Great interview. Thank you Thomas and Josef!
Very detailed interview. 👍🏼
I have the Prusa i3 MK3S and when I cut the filament, it jams and I have to take it out with pliers! It does not spit it out like the demonstration in this video. Also whenever there is a filament jam, the 3D printer does not sense it! What am I missing! ? anyone else having the same issue?
do you have the feature turned on?
I have it as well and it works
A living god! *
Will they have a dual extrusion version of this?
I like it open source. Next printer will be a original prusa ☺
I don't quite understand the how they are getting higher microstep resolution. Josef mentioned that they are using 16 microstep instead of 256 which the driver is capable of... but they are still getting good resolution some how? I'm confused.

Wow! Thanks for the explanation!
That doesn't improve the resolution at all... It only makes the motors quiet. The way interpolation works it splits a single move into multiple smaller ones, but the movement is still the same.
Any word on a quad extruder upgrade/version mk3?
Very nice software features, but the hardware is still quite disappointing for this pricepoint. There are way too many 3D printed parts for some of the critical portions of the printer. Sure it works, but linear rods, bearings, and motors should not be mounted to plastic printed components in a printer of this cost!

love it cant wait to get one
Nice interview!
That's it, I'm buying that.
"MK3 Prusa" alias "The unstoppable Prusa"... cut the filament, cut the power, bump in one of the axis... it will just continue "it's mission: to explore strange new opportunities, to boldly go where no one has gone before..." :)
Why not just call it the i4 if there are so many changes and it's generally outside the range of upgradability?
Bert Green i3 is the type of printer, MK3 is the revision.
Next time your 3d printer will be ur next Desktop Computer too haha XD
Kind of ironic that he talks about temperature drift when Thomas himself tested it and found the drift to be negligible ;)
But like he said though, they did find some users needed to adjust the z height. Clearly it was needed?
So is the mk3 compatible with multi material upgrade?
Yes, an upgraded MMU will be available a few weeks after the Mk3 ships.
Wow. Major improvements.
I think i'm in love
Hello, is the frame made out of metal?
Yep. duralumin
Why not dual extruders?
Dunt m3d have skip detect?
yes!
Anyone know how they get such a smooth Z?
Owner of MK2S + MMU, Is there any plan for us ? an 2.5 MMU upgrade ? Nobody ask about this ?
Yes, it will be available a few weeks after the Mk3 begins shipping, I switched my Mk2s/MMU order over to the Mk3 including the updated MMU with extra filament detectors. Not sure you can preorder the ungraded MMU yet since they have not worked out the pricing difference.
William Dutcher not sure you well understand what I ask. I already have the mk2s upgraded with MMU and it works great. So my question is not about existing an mk3 MMU but if an upgrade kit from mk2s+MMU to an equivalent of mk2s 2.5 upgrade but with 4 filament detector per example.
Sorry, I did misread your question. While I can't speak for them, I think it would be a mistake for them not to support the MMU upgrade path. Just requires 3 additional sensors, cables, and 3d printed extruder enclosures. In fact they should allow the MMU upgrade path across the board even without doing the Mk2.5 upgrade. Since the MMU is much more sensitive to filament jamming issues. Hopefully they will see the logic in doing this.
William Dutcher Agree ! Filmanent gesture is the most tricky part of MMU and filament sensor will greatly improve the « easy of use »
Great great great !
Uuughhhhhh, that's it I'm burning the Chinese i3 clone I've spent hundreds of hours tuning and improving and getting one. Not sure how I'm gonna afford it but I'll find a way.
ı was going to buy anycubic i3 mega but now I want this
