"It is now printing at 200mm/s because it is the first layer, it will speed up..."
Let that sink in. I print my first layers at 20mm/s.
exactly my thoughts... now I am curious and want to see how fast I can print my first layer at ... maybe I can push my luck and do 30 mm/s? lol
My printer starts at 40mm/s but it’s a delta do it can do 100-200mm/s on regular layers
But this is incredible
If you had used a smaller nozzle could you go faster still
@@kendell8046 Wouldn't that actually result in a slower print speed? I don't know if you would be able to eject enough material through a small nozzle fast enough to get up to these speeds. Also, I think you would need a bit of a higher temperature to get the material to flow well enough through a smaller opening and not clog. But I could be wrong here, just a guess.
I think it would be fun to see a benchy or some other model speed run and see how fast you can get a successful print.
That's such a great idea, now i'm sad that this video didnt do that :(
@@Drakoman07 Because it would have came out like a turd.
Due to the short line segments in such a detailed model as benchy, I don't think it will accelerate all the way to the topspeed, so it wouldn't be a comparible result
There's not much difference in a model like a benchy, as the printer won't reach max speed on any segment. That's why the model he's used is a bunch of long straight lines, to give the printer a chance to accelerate to the target speed. It might be interesting to see a giant benchy though, scaled to the biggest side that would fit on the bed. I don't think it would be able to reach max speed but it should reach higher speeds than a 1:1 benchy.
@@suharsh96 Well then, if we're not going for quality here I'm sure I could crank out a benchy at 400 mm/s on my printer. Hell, i'll just tell it to shart out a bunch of filament in a pile at 800 mm/s and call it a benchy speedrun.
If you print a pentagram with 666m/s a portal to another world will open.
Take one print with infill man
doom guy: ah shit here we go again
666 meters/s seem kinda fast to me
I'll be impressed if you print anything at almost twice the speed of sound
u should use pentagram infill pattern!
This is the 3D printing version of liquid nitrogen CPU overclocking, good stuff.
The thing is that these speeds are not accurate in the same way cpu clock speeds are read. There is no way to measure the speeds, sure anyone can order their printer to print at 1000 or 10,000 mm/s but the acceleration is still too low to achieve it. It certainly is moving very fast, just not 700mm/s fast.
In no way can you compare this to liquid nitrogen cooling! Because speeding ya printer up is actually a good idea
To be clear, this comment is a bit of a joke.
@@rikdenbreejen5230 XD
@@rikdenbreejen5230 It's just a playful analogy.
T Turner, my comment was a bit of a joke.
I'd love to see this beast printing a simple cylinder in vase mode. Should be able to reach even higher speeds without the cornering issue.
Great work.
Yeah I was thinking the same! Would be really cool.
But I guess the lesson for this video is that you need to work on the melting in the extruder. It would make more sense to print at 400m/s with 0.2 layer height than 800m/s at 0.1.
@@dejayrezme8617 unless you're a sucker for outside wall quality
Print my head!
the opposite is true.
that circluar vase has a few hundred thousand more corners then the print from this video
@sourand jaded
and it's not like the control software is going to give a damn about the angle of the bend.
infact it doesn't even know.
make a circle.
slice it.
and you get several thousand lines of code for tiny individual lines. (PER LAYER)
without ANY info on the angle of the next line.
and it's just coördinates.
G1 X0 Y0
G1 X0.01 Y0.0
G1 X0.02 Y0.01
G1 X0.03 Y0.01
G1 X0.04 Y0.02
excetra excetra excetra
and it is going to treat them as such.
you can tell it to go 800m/s all you want. it won't go faster then 50m/s (depending on the resolution of the circle)
you can then change play with the speed setting as much as you want. it's going to print it at the same speed each and every time.
however, if you change the jerk and acceleration, THEN suddenly it starts to go faster (or slower if you lower them)
if you have a 32bit motherboard and some special code in the firmware. it could look ahead in the g-code
and begin doing some math. (basicly turning all those G1 straight lines, into a G3 or G4 circle, then it suddenly does have the info of the angle on the corners, and it can decide to go faster because it doesn't need to slow down as much)
you can also install a plugin into the slicer. and as long as your firmware on the printer knows what G3 and G4 is. the slicer can just write (G3 with the coördinates of the centre point of the circle. the coördinates of the end point of the circle. and perhaps a radius) and it would be faster aswel.
and then you can print faster circles on an 8bit motherboard aswel.
next time you don't know jack shit about a subject. try to just ask a question. rather then pretend you know something and make a fool of yourself. or just shut up. either or.
learn how to program a lathe or mill with fanuc iso control before you come back.
(not heidenhein. that's the easy mode)
marlin and most 3d printer firmware is a childs toy compared to real cnc. and 3dprinting shortcommings show this well.
the industry is starting to reach the point where they need to start creating filament specifically for printers that run over 200mm/s
I wonder what the theoretical limit on speed is. At a certain point the filament would have to be near-liquid just to come out of the nozzle fast enough, and eventually it would just be a jet of molten filament coming out like a water jet knocking over anything already printed. At that point you might as well just stick a mold under it and call it an injection molder.
You'd need to focus on a longer heating chamber, so it has time to conduct heat to the centre of the filament before it reaches the tip.
@@DUIofPhysics i could see induction heating with a fluxed core like welding rod in the future as feed stock
@@nikolaivillitz6026 If we talking this to the extreme, we are talking about spray painting molten plastic!!
@@DUIofPhysics I'm melting more than 200g/h with my Nova hotend (47mm³/s or so) and I can tell you, neither specific filament or a ridículous long heatzone are the way to go, I can push that stupid amount of (relatively good) regular plástic (I think it's the same ingeo resin as prusament) and the Nova has a heatzone of about 18mm, sooo
This just shows that 3d printing can progress to a speed that would print in acceptable times as the technology improves.
We are a long way off high speed prints for a while though - 3d printing is still pretty much in its infancy at this point..
I can only imagine the stress that all the motors are going through, this has to impact on their working life.. and the noise is something else entirely!!
Who knows how far we can go in the future? Who would have guessed 50 years ago that we could have computers the size of a matchbox and 3d printers making all kinds of objects, some even for medical applications?
Yeah, stuff of science fiction, but we will catch up..
Good video, well done..
Imagine in like 50-100 years when we're all printing live tissue with this sort of speed. Want a cat? 5 minutes, tops. Accidentally lobbed off a few fingers or your arm while working on the ol' hover-mobile? Go to Fiverr and have someone make you a new one.
Nikolai, you may just, but it's all entirely possible in the future.. if you watch today's sci-fi, it's a fair indication of our future..
Anyone remember the first 2d printers? These things were slow as heck, jammed all the time and required constant supervision - sounds familiar?
Probably we'll never achieve StarTrek replicator speed of 3d printing (because of that pesky thing called basic physics) but I am sure that we'll eventually achieve 3d prints that are done in minutes instead of hours and have acceptable quality. Maybe even full color 3d prints where printer would just melt together CMYKW (W=white since it cannot rely on the medium such as paper to supply that color) filaments in right proportions to get proper color.
@@UltimatePerfection in the movie "face off" (John Travolta/Nicolas Cage), there was an ear being 3d printed in a fashion very much like resin printers.
That film was 20years ago - who would have imagined that 3d ears and hearts are being made in today's medical industry?
You are right about 2d printers and the resemblance..
Who knows where well be in future years..
Just get servo motors, and then you Can optimize them to a ridiculous level

Started watch at 2x speed: "Wow! Thats pretty fast!"

Nice! At these speeds, you should really try an ODrive with BLDC motors. I am curious how fast speed could you achive with those.
Sir this is very awesome print
I love seeing the zirc on that linear nut. Impressive machine. Congratulations.
As somebody who has to wait 47 hours for some prints, this both intrigues and sexually arouses me.
you would probbably shave about 1 hour off of that time with speeds like this.
you can tell your printer to print at the speed of sound. but if it doesn't have enoegh lenght in a straight line to ramp up to said speed. it will never get there.
i can tell my printer to print at 800mm/s but then print a cilinder. and it will only print that thing at about 100 maybe 150mm/s
why? because jerk and acceleration are limiting it's speed. because that circle is hundreds and hundreds of tiny straight lines that it keeps needing to slow down and accelerate for.
@@darkracer1252 say hellooooo to arc welder
Thanks, now I don't feel alone... Either a Hevort or a Voron build is very near in my future. I'm instantly obsessed.
@@darkracer1252 I think that's a great point. I have to ask, as I'm somewhat noobish, wouldn't the absolute maintainable speed (I want good print quality too) be directly dependent on the geometry of the part you are printing?
@@TheJacklwilliams yes it is. and as cris mawson says. arc welder helps (it's a plugin on cura that turns circles in circle commands rather then straight lines)
so the thousand or so lines of code for the short lines that make up a cirlce will be turned into a single code.
but what cris didn't understand is that that doesn't change what i said.
jerk and acceleration has nothing to do with the amount of code. arc welder only helps if you have an 8bit controller.
it's STILL thousands of tiny straight lines that all require it to take jerk and acceleration into account.
if you have "junction deviation" set up though it will slow down minimal because it takes the angle of the corner into the equasion.
so that's a jab at you cris mawson.
arc welder is solution to a slow cpu. not to slow jerk and acceleration.

Nice build. Awesome speed.
Very nice job my friend!
I've never seen some things like that!
God bless you
If you need to go faster without skipping steps, try what is used in slot machines with large reels.
what is used?
I want to see how extruder motor is spinning at those speeds 🤯.
I would be perfectly happy if I could reach 150, at 400 I was blown at 600 my face could be used as a meme.
I've never saw that amazing speed! It's something like: from dream to real in a eyes blink! :) My compliments.
Very impressive for rapid prototyping good that you find the limits

First time seeing this project. As an engineer I was already thinking from the title "how the heck could the tension belts and motors handle that speed". Your design solves that problem.
I'd imagine you'd run into severe stringing issues if you were printing something that required travel. Following👍
That is a very good test idea. Stringing at that speed. Never had an issue with stringing though. Pressure advance does most othe work. A slower retraction also help in order to avoid the fusion bath to break and let some material fall loose from the hot end.
Lol, Im gonna try these settings on my printer🤣
Congrats and this is amazing stuff!!
Amazing! I've not tried to do the math, but I wonder where the CPU performance of the controller being able to compute the kinemetrics and driving the steppers becomes the bottleneck? And when you're out of CPU cycles, how is does that manifest?
A printer like that needs yellow and black hazard tape around out; you could put an eye out with that thing! :-)
I did not do the math until I red your comment ;) but here it is :
- Duet 2 Wifi has a total step capacity of 300kHz
- GT2 20 teeth pulley have a diameter of 12mm = 37.7mm circ
- CoreXY staight moves are obtained using the two motors. 800mm/s is the the hypothenuse of the displacement. Each motor is supplying 565.7 mm/s.
- I am using 400 steps/rev motors =
- The motors are configured at 16x microstepping. (each physical step is divided in 16)
Number of motor revs per sec = 565.7 mm/s / 37.7mm / rev = 15 revs / sec
Number of steps per second = 15 revs/s * 400steps/rev * 16 = 96,034 steps/s for one motor.
Total Steps for XY = 192,068 steps /sec
The Z axis will be negligeable since it will be moving 0.1 mm each layer.
Extruder = 16mm/s is required to achieve 0.1mm layer at 800mm/s on a 0.4mm nozzle. Using the E3D hemera @ 409 steps/mm this gives us 6544 steps/sec. Not a big deal.
Total: 198,612 signals(steps) per second on a capacity of 300,000.

I used to print at 0.15 mm layer height but after working out the numbers for my z layer height for my 4 start threads, it made sense to print at multiples of .04 mm, so .12,.16,.20 layer heights because the steppers don't have to maintain an in between step and there is no noise or z motor heat.
We need more people working on this along with Top Down Resin printers... Right now my DLP printer is going through testing, at 10 cm per hour on the Z height with a build plate of 384 x 216 mm. Hoping to replace the LED in the projector to cut the time down to 35-45 minutes, the only problem then will be resin viscosity and wiper splashes.

Yeh... can you print a benchy at that speed? Would love to see that result. This video is amazing. Great job!
Absolutely as it would not get even close to those speeds without the long straights. It would look like crap though as the layers will not cool at all.
If you're developing your own printers, I'd like to see the possibility with changing out the belts with ball screws and changing from steppers with small steps to the kinds of brushless motors seen as part of hobby RC aircraft. it can reduce ringing a good bit as the elasticity of the belts is the major cause of ringing, while also keeping step ratios similar to what they were on the belts, because geometry
This is how fast 3D printers should run at. I know as technology advances this will become the norm and thank you for pushing the limits of what can be done.
If 3D printing is to progress this sort of thing needs to happen.
Be nice to see a benchy being made to see what the quality is like at the end of a high speed run.
Exactly my goal! Unlock the true potential of FDM printing. This technology can do a lot more.

What I have found to work best on glass surface is the printing material itself. I splash some acetone on the glass (that I cleaned with acetone) and rub a failed part on it. The acetone melts the material, forms a film of the printing material itself as acetone evaporates away. Quick to apply, disconnects clean once the glass cools, leaves glass like first layer surface.
Yes, this works great with ABS, but PLA and PETG dont disolve well or at all with acetone.
I think a larger printhead is needed with a longer heater barrel to melt more plastic. Reducing layer height just to go faster is useless because it will not produce any more output. Another option is a different nozzle design that can "brush" or pipe fully liquid material onto the layers and turn up the heat.
Really puts the Rapid in Rapid prototyping.
I have a Prusa i3, but still felt i learnt useful info on diagnosing print issues from your video. Amazing speeds as well!
amazing!
nice man! if you're gonna go at those speeds, you'll need something like a Nova or a Supervolcano lol, but it's super nice to hear people starting to push the envelope! I absolutely love printing fast and think everyone should! it's certainly possible to make a commercial machine print 200mm/s out of the box
How does the fact that he prints with 657 mm/s and 8k acceleration with no problem makes you say that he needs a nova or supervolcano hotend? After all at that speeds, it's not about how fast you can melt plastic but how fast you can cool it down so it adheres and doesn't produce spaghetti.
Super Volcano will give me margin to increase layer height. It is sitting next to me... waiting eagerly for me to finish the design of its carriage. :)
@@MirageC I think the next issue will be the long heavy hotend flying around, because it is fastened at only one end with a weak heatbreak. Probably you will need some diagoal braces at the bottom in at least three directions. Made out of thin steel or stainless steel wires, which conducts heat badly and not heavy.
@@moczikgabor I am developing a solution for that matter. A piece of PCB phenolic with heat dissipation copper tracks that will link the bottom of the supper volcano back to the carriage :)
@@MirageC Oh, cool! We eagerly waiting to see it in action. 😉
Magic !
Ici à Bruxelles, on apprécie beaucoup vos vidéos mais pas seulement vos vidéos et votre projet d'imprimante 3D haut de gamme, nous apprécions aussi vos trams (il n'y a pas de hasard, both are real bombers)!
Phlupke et ici à Montréal on vous remercie beaucoup pour votre mot d’encouragement:)
Incredible engineering!
Of course we want more, learned a lot.
Would closed loop motors help with overshooting?
How could extruder be made keeping pace?
What perfs can be reached in other kinds of prints like vase or usual bench parts?
Do you think the symbolic 1000 mm/s barrier is reachable? How?
This is fascinating, thank you very much for sharing?
If you mount actual linear encoders, i.e., glass ones with optical readout, it should be easy to get the required precision, and a sufficiently-symmetric frame would be able to prevent induced torsion.
I actually thought about using a fringe-counting laser interferometric "encoder", which would probably be fed with a fiber-coupled He:Ne laser for it's ease of operation and beam quality. It would use a mirror on the carriage to reflect the beam, and then just detect in which direction the fringes move with two photodiodes that give a direct analogue quadrature signal.
For more extreme speed, I thought about using copper-clad non-magnetic-steel push-rods with an linear induction motor. It would have 3 coils around the rod, one after the other, and rely on closed-loop feedback for position control, as it can natively only create a choosen force if it already knows the velocity. The good thing is that it can operate at really high temperatures, and thus very high power levels, allowing for insane accelerations of >100 m/s^2.
The hotend speed I considered tackling with a small screw extruder, where the inner screw would be ground by a small stepper-driven purpose-build CNC out of a piece of 6~10mm M42 tool steel. That's very temperature resistant and should have no problem with things like PFA which _melts_ at 310C and is typically extruded at 380-450C. It's basically like Teflon (PTFE), gliding better, being more resistant against chemicals, useful up to 260C, but a bit softer.
Pretty damn cool. Liked and subbed.
Can I make a suggestion about improving your videos? Maybe try a script or bullet points. It gets a bit painful listening to anyone hunt for words, and some notes might help with that.
I will definitely be keeping an eye on your channel to see what you do in the future!
Thank you for the constructive feedback. :)
It's good advice but entirely impractical for videos involving real-time commentary rather than post-facto. Beyond that, while word-hunting can get annoying, and sometimes very quickly for different people or in different contexts, use of a script can and will often make a production feel disingenuous and discomfiting to both producer and audience alike in a way that word-hunting rarely manages to approach. This becomes a significantly more likely outcome when the producer in question has a standing practice of real-time commentary, as here.
Love this project. I want to build this. In this configuration what is a ballpark figure for all the parts?
