Wire Bender

Open-source wire bending CNC machine for wires at 1mm and less in diameter.

Similar projects worth following
I build sculptures out of brass wires and since I hate repeating creating same part over and over again I decided to build a wire bending CNC machine that would do the job for me. So far it is still an early prototype but looks promising! The goal is to build a machine that has most of the parts 3D printer or easy to get so everybody can build it at home.

All the resources will be available on GitHub https://github.com/jpraus/wirebender

how do you get the wire to form a spring by bending in 3d? should it just continue bending in the same plane and overlap the previous curve? great work ! i am also building a modular wire bender but got stalled because i don't have a reliable feeder. also eventually u will need to add a servo to raise and drop the bending pin if you want to bend in two direction ( left and right )

For some reason, a wire sculpture of Bender from "Futurama" does not appear to exist on the Internet. Might I suggest that you should use your wire bender to make a Wire Bender...? ;)

Last year I spent some time developing a machine that will cut insulated electrical wire to various lengths.  The main stumbling block was the feed mechanism which, like yours, kept slipping.  I used a similar approach of pinching the wire between a stepper-driven, toothed roller and a bearing, but couldn't get it to work reliably.  Have you solved the problem in your version 3?

Love this simple design.  I am often re-bending paperclips into different spring shapes.  I have had it in the back of my mind that I would like to automate it.  Right now, I 3D print bending fixtures to make repeated parts.

Is this project going to be open-sourced?

Fantastic design, I could watch this thing go all day.

Sweet. How's the rotation done around the wires' axis?

  Are you sure? yes | no

Jiří Praus wrote 07/04/2019 at 18:34 point

Currently, it is an unwanted rotation caused by drive gears. However, I've added the straightening phase and it holds the wire at a still angle. But now the problem is the drive gear which has low adhesion so I am upgrading that one :)

When this 2D bender is done I want to experiment with second axis to create 3D bender.

Nice, sounds like a good plan! See https://youtu.be/5QjVeH2Z57E for your wire bending porn needs :D 

No, srsly watch that short film if you haven't yet. It's mesmerizing to say the least...

@Jan that bending porn is perfect. They even colorgraded it to an amazing style.

check thé 90 degree rotation at thé start( where thé wire enters) and thé coil size determins latéral motion.  There are other factors innvolved as well.  But that la à start :)
