Making a Hot Wire Foam Cutter | 3D Printed & Basic Tools
HTML-код
- Опубликовано: 28 ноя 2020
- This is a simple handmade machine I designed and built in order to cut foam or polystyrene. The theory behind this device is really simple: A thin nichrome wire is connected to 12 V DC using a DC power regulator. The current flowing through the wire turns it really hot (it glows in the dark). Then, pushing a piece of foam or any similar material causes it to melt, leaving a perfectly clean cut. In order to build it I used 3D printed parts, basic tools and some materials that you can find in any hardware or DIY shop.
Thanks for watching!

I have no plans on building this thing whatsoever but the quality of the build and the video hooked me to watch the entire thing, amazing.
I'm so happy to read that! Thank you for letting me know 😉
As someone who's used hot wire cutters a lot, great job on those cilinders! Even with professional equipment a lot of mine still come out all wonky..
Excellent work!
I'm always astounded at the level of polish on your designs. The few things I've made are a constant jumble of barely good enough.
Thank you for your kind words, Phil. Just keep designing and you will get better for sure!
Impressive 3D build. And your filming/documentation skills are awesome as well.
Thank you for your kind words Gilberto 👍
Really clean build, I like it a lot! As a future improvement you could add a spring to the wire-fixture. This way it is always properly tensioned, even when it expands due to temperature change. Some slack is visible around the 13:45 minute mark. Keep up the good work!
Thank you Hang Lee! To be honest I wanted to avoid using a spring and use the aluminum tube flexibility on its own instead to keep the wire tensioned. Maybe I should use the third hole to increase it a bit. The problem with springs is that it allows the wire move off center more easily, loosing precision... Thanks for your feedback!
@@EliteWorm Thanks for your answer, I honestly didn't think of that! Maybe redirecting the wire at the top 90 degrees over a ball bearing could work in combination with a spring? Grinding a small groove to keep the wire at position? I'll have to test it out ;-)
@@hangleejakamoto2348 Yeah that's the perfect solution 👌
Great topic, thanks 👍
You are a very talented designer!
wow this is stunning, it's both functionnal with great engineering and stylish and clean. Amazing job!
That's what I try! Thank you, mate 👍
Proyecto super chulo. Y más cuando te enteras de que viene de un maker español!
Gracias! Por la bobina de hilo, no? 😁
@@EliteWorm y por las herramientas de dexter jajaja
Very nice engine, I'm impressed!
I really like your designs, thanks for sharing.
Nice work man!
Brilliant
amazing, i love this
Awesome project. I would love to make one of these
Thank you Cole, I will upload the files soon!
This is geat. i love it
nice build !!
Love it ! good job
Thank you 😉
very well done ! good job
Thank you Sven
Awesome
hello a french yutuber of 40 000flower who talks about 3d printing to talk about you and you made an advertisement :)
Do you have a link? Thank you!
@@EliteWorm yes I give it to you. it is towards 1; 23 which speaks of you
@@EliteWorm I suppose you don't speak french but know that he said a lot of good about you
:)

Thank you for sharing, I learned many interesting things :)
Thank you for watching and commenting 😉
Nice!
Thank you mate!
Great design! But I can't find the 1 x 10 x 12 mm rectangular aluminum tube, it's too hard to find.....
Great project! Are you planning to release the print files?
I'd definitely be interested in a parts list and the STL files you used!
Thank you! Yes, I will release the print files later today. I'll leave a link in the description 😉
@@EliteWorm Thanks for sharing. I so want to get back into making something with the hot wire cutter, whether foam or even HDPE or other polymer. I was just reminded again last evening, since I have a stack of foam trays (I know I'm best not to eat meat packaged from) I've been saving for an RC aircraft build. Is a lot less mess cutting plastics too when tuned right.
@@jafinch78 Cool! So just go ahead and build this thing 😎
A foam cutter with this many features is $200, so thank you.
Love this design and simple assembly.
Could this be changed to USCA for us American friends, or original step files uploaded so we can modify it?
Plz make a fast 3d printed rc indoor speed/drift car
Geees, that's an elaborate design. But I love the final fit and finish. I made one out of ply, but it sure don't look like that. Do you sell that 3D printer file?
Thank you! It’s free in my Thingiverse profile!
Already printed out. Just waiting on amazon to deliver my controller. Do you have the file for the measurement sticker on the bed?
Hola Muchas gracias por compartir increíble trabajo esos componentes los vendes no hablo ingles disculpas. Saludos desde Argentina
Hola Gustavo. Gracias a ti! No los vendo pero subí el diseño a Thingiverse por si quieres hacerte uno.
Hi, awesome project! I'm definetely gonna make it ^^
Does anyone here maybe knows how to add a temperature display for a wire?
You wouldn't happen to have a link to the screws you used to attach the controller, would you?
I don't, sorry... I bought them locally!
i like this video, everything seemed fine until 3:40 , GAH why!? use a funnel god damn it. YOU´RE MAKING A MESSS!!!!
merry christmas.
The inner diameter of the tube is smaller than it seems. I already tried using a paper funnel and it didn't work... Merry Christmas 😁
have you done cutting in XPS Foam alias Styrodur? would be very handy for Tabletop Terrain.
Hi Knut. No, I haven't tried cutting Styrodur but I'm pretty sure that it would work as well!
This a great and fine project! Congratulations! For someone without all the technical skills and tools (3D printer, integrated circuits, etc) could it be possible to purchase the complete machine already made? If so, where? Thanks. Cesar from Bogota
Hi Cesar! Thank you for your kind words. But I am sorry to tell you that it is not possible for you to buy the machine already made… The only possibility I can think of is to order the 3D printed parts online, and try to source the rest. Good luck 👍
Thanks a lot for your reply!
What gauge of wire is being used for the power?
Very cool project! How long did it take to build it?
Thanks. Printing all the released files should be around 18h and then building it maybe 2h more... But it's hard for me to know since I was also filming it, doing some trial/error, etc.
woah, amazing work! thanks for sharing! anyway, can it cuts EVA foams?
Thanks Gregorio. I haven't tried it but as long as it melts you should be able to "cut" it.
Cool build! For what are you using the foam?
The bag where I store my camera is slightly too big so I wanted something to protect it and hold it in place. Nothing better than a custom piece of foam with its exact shape!
Link to the control circuit?

Hi there, can I commission one of the hotwire cutters please ?
Hi Theo. I am not selling these but you can print one yourself. I posted all the files on my Thingiverse profile.
@@EliteWorm great and thank you. Really nice design. Well done.
