DIWire Bender via Core77:

In recent years, 3D rapid prototyping machines have gone mainstream. And we’ve been excited to see 3D printers spreading beyond businesses to individuals, with the aid of a little DIY ingenuity (e.g., Makerbots, RepRap, etc.). All these machines work on the same principal – to create a form, they split a volume into thin slices, and build up the form by printing a layer of material and bonding it to the next. The main difference between the build technologies (SLA, SLS, FDM and others) is the material and the bonding methods.

But there are times when we need to output lines in space rather than volumes. Most 3D printing technologies are not well suited for printing thin lines because the materials are weak, the machine uses a lot of 3D-print support material, and the process is slow. The closest thing to a machine that can output lines is a CNC wire bender, but these machines are used almost exclusively for mass production in factories. They are not used for rapid prototyping because the equipment is large, expensive and takes trained personnel to run. So, we decided to make the DIWire Bender.

The DIWire Bender is a rapid prototype machine that bends metal wire to produce 2D or 3D shapes.
