This is a Styrofoam cutter made using LEGO bricks.
This device cuts styrene foam with an electric heating wire cutter. The electric heating wire of the cutter is not a Lego element.
It is numerically controlled by Lego Mindstorms EV3. Software is still insufficient.
Three examples are explained in this video.

that last thing... was oddly satisfying
I read this comment before I watched the video.. this is true
the way the diagonal wheels fit perfectly and rolled smoothly onto the side bricks at 1:36 was so satisfying. such a precise and clever build.
and not to mention 8:03. speaks for itself...
when video :(
0:12 "This cutter is not a LEGO brick" Thank you for that.
But anyway, this is an awesome build! I have a similar handheld foam cutter, and one thing people who haven't used one might not know is that the wire often doesn't even touch the foam! Most of the "cutting" action is just the heat from the wire melting the styrene enough to release the air trapped inside of it, causing it to shrink away from the wire. And while that property is what allows it to glide through the foam so easily, it also means that the kerf (the width of the cut) varies considerably depending on how quickly or slowly you move the wire through the material. That makes it very difficult to achieve clean, attractive cuts by hand, which is why this CNC cutter is so cool!
But even with this, the dwell time on the last piece (the screw) would vary considerably depending on the proximity to the axis of rotation, so the kerf would be thinner towards the outside and thicker towards the middle, where more heat can build up. Oh, and going back to the point about the wire "cutting" by melting and popping the cells of the foam, I believe the reason the "0" failed to detach completely was because of how the wire traversed the same path as it was entering and exiting the center hole cutout, so the material had already been partially melted and re-hardened, causing it not to recede from the wire as much, and therefore to re-fuse to itself slightly. At least, that's my theory.

I once just bought the wire and built a really big cutter with it. I used a train controller for power. It worked really well after a few improvements were made to it.
whenever akiyuki posts it's a good day!
awesome build!
I swear every time I think to myself “akiyuki hasn’t posted in a while” I see a new video within a few days! And it always feels like such a blessing!
It’s also a lathe. Set the piece to spin continuously like the last one, and you can use it like a very slow moving lathe
That is beyond cool. The level of precision on the finished product and what it makes is unreal!!
He became literally a tech gadget engineer. His hobby became his profession.
the percision is really impressive, especially considiering it was made with legos
Heated Chrome wire cutter, played with it a lot - that brings me back a nostalgia! absolutely love your builds.
few years ago i was the cnc operator at an EPS factory. this thing is better quality than what they had me using..
I'm a student machinist I just feel weird seeing the words 3-axis in reference to the X,Y, and A axis instead of the usual X,Y, and Z axis. I'm too use to associating the A-axis with 4-axis machines.
I guess you were cutting man sized blocks like my dad used to .
It's such a shame Lego has discontinued mindstorms
They did? Wasn't there the robot inventor something?
You should make this open souced! I bet cosplayers would love having a fairly cheap way to make precise foam pieces for their armor and props
Also a big version (lots of bricks) to cut standard factory blocks into life size human sculptures .
Amazing engineering as always, Akiyuki.
すごくすごい！
This would be perfect for lost foam casting
この世は理系の皆様によって支えられてるんだなぁと再認識した動画
数字と計算が心地いいのがakiyukiならでは
It’s wonderful! Hooray for Lego Technic! I have seen Adam Savage cut styrofoam with a wire, but that takes much skill and hand control, and I’ve never seen anyone make a pair of screws before, wow. Beautiful chess piece too (only 31 more to go!)
its a lego styrofoam CNC, my mind is blown
全て計算の上で成り立ってるのは解るが自分の脳がこれを出来るとは到底思えん
科学者ってほんと凄いよね
Akiyuki is KING!
I think you can make amazing 3D airfoils with this thing. Even large airfoils or flying bodies can be manufactured in small segments and just glued together on a more basic structural frame.
Brilliant. the airfoil idea is genius
Incredible, how does the programming work? Do you have to manually input each motion, or do you use some sort of software to automatically translate an image into motion?
impressive crane base seems really well built and sooo good
0:13 "the cutter is not a lego brick" is very funny to me
Very impressive and precise. Thank you
すごい！
どうやって機械をスムーズに動かし続けましたか?モーターは非常に精密です。レゴのギア間の隙間は問題ですか?
確かに、 2:40 ぐらいの接写のときにLEGOでこんなに高い精度を出せるのかと私も思いました。ギアの構成がどうなってるのか気になります
this is really cool! it's like a foam lathe
So good, really good work
Very nice work!
A foam lathe, Impressive!
Thanks for a great video.
Very well done! Thank you for sharing!
that's pretty neat!
Awesome Project! The thought of the sound of untwisting styrofoam hurts my soul
My best friend was like that; never rub two pieces of styrofoam together around him.
That is the craziest thing I have seen done with Lego robotics yet
There are two types of people in this world.
Those who can extrapolate from incomplete data
man, what happened to Lego in the years since i was a kid? i only know of lego as the square bricks, not all these fancy tubes and gears and sliders and mechanical devices. it's come a long way, huh
insane coincidence! i just built something very similar to cut piece for lost foam casting. good job!
this is so cool
Best way i have seen to cut a block in half
Most styrofoam plates are made by pushing a block through a hot wire egg slicer . I remember the factory having slicing frames for different plate thicknesses like 5cm and 10cm.
That is extremely clever... well done
It'd be cool if you used this for some lost foam casts!
Great work dude 😁😁
I can see this being useful for foam aircraft like you could program it to cut specific parts
or for cutting air foils
This is a really cheap way to have a CNC lathe for molten cast negatives. Or just mold casts in general. Has to be cheaper than 3d printing as well.
For me the programming is even more impressive
Very cool!
That is brilliant!
Who needs a 3D printer when you've got this
this would be perfect for metal working
Amazing
Now make a giant minifig out out of foam!!
Styrofoam 1x2 bricks are too big for this lathe . I had some in the 1970s from a test production run .
I would love to see a combination of the two last settings a round pillar and a spiral. Instead of a square spiral.
すげーーー
Wow, i cant even imagine how hard wold be to program a slicer for that thing 😨
you are a Lego Technic Master ! realy !
Would love to see you mount it upside down on something, so even the big 3rd axis slices fall away without help.
That screw piece blew my mind
Combining hot metal and plastic, surely nothing could go wrong.
how did you program the EV3 brick? was the gcode parser written in the EV3 visual programming environment?
Its amazing what people build out of legos but it not werry ofthen people make something that is actually really usefull
Our boy here opening up new frontiers of what is possible with lego =0
this would be great for the lost wax mould type
Who’s going to be the first to make a surgical robot out of lego? It’s only matter of time…
I wonder if you made the spindel turn a bit fasterfaster and used a shorter wire, sort of like a half oval shape to cut, if it would work as a lathe to make rounded parts
Unexpected, but still cool.
Lego cnc Styrofoam cutter? Cool
very cool :)
This is essentially a CNC machine for Styrofoam made from Lego.
Nice. The tricky part is tool path generation.
Impressive
would be nice if lego made this into a lego set
You could try adding a small arm to push off the spare styrofoam as it cuts
That is crazy!!!!
The musak was perfect 😂
how cool is that? 🤩
That is some impressive g code
手がおキレイですね(*^^*)
this guy makes a CNC machine out of lego
A fellow Muse Dash enjoyer I see :D
Just wow
Titans of cnc has some good vids on wire edm if yall want to see this same concept cutting steel.
You should try making it rotate faster and use it like a leive
the selection of music is vastly preferable to most...
right. now, make one "chuck" open, on a ring.
then stick a hot element up the center. internals would be interesting :)
Well, that's fucking neat.
Bro, he basically made a 3D resin printer but instead of resin styrofoam and the printer is out of Lego 11/10 was it cheaper than an actual 3D printer? (cuz I might wanna build one myself…)😅
Next video:
building a fully functional 10 axis cnc machine from lego.
Великолепный лего станок да и работает на все💯%❗. Вы умничка 👍
What kind of tolerances does this machine keep?
How do make the CAM/write the .gcode for this?
people like you need to be working at nasa
The most expensive cnc machine known to man
레고로서 신기할 뿐만 아니라 실용적인 인쇄기로도 쓸 수 있을 것 같네요
So you've made... a CNC machine. Impressive.
Whaiit… that’s reminds me something. Last step is to add red lazer and anime girl
I half expected you to carve out "Like and subscribe" or something.
Underated
That's of the the chain
