Toward 3D printed Circuit Boards

[avocadobaby]

I have thought up three or four methods for making circuit boards with 3D printers

Hey have you looked at these methods. most require some hardware modifications and 4/5 are for 2d circuits

1. Solder extruder for reprap printer http://youtu.be/Wnu4lmOnX00
2. Laser circuit etching with a reprap http://youtu.be/Chq6TcTeDJc
3. etch resist sharpie attatched to reprap http://youtu.be/QmgCw6b3d3Q
4. turning a 3d printer into a pcb CNC miller. (could be done with a reprap) http://youtu.be/AorVxw305DA
5. conductive ABS filament ( it has some resistance) http://youtu.be/Z8uWpXMxMi8
