Conductive filament for 3D printers

Tom Simon

I'm curious to know if anyone has played around with the conductive filament that Proto Pasta has available?

Electrically Conductive Carbon PLA Composite – ProtoPlant, makers of Proto-pasta

While probably not good enough to route a PCB due to resistance, it seem to offer a very interesting way to add wires to projects using a novel method. Adafruit has a sample project that uses this filament for LED's on 'gloves'.

It seem that this cracks open the doors for using 3D printing for electronic prototyping.
