3D Printing PCB Etch Resists

I hadn’t heard of this before, so I thought I’d share. Somebody’s gotta try it.

Basically, this guy printed his etch resist directly onto copper clad board using Ninjaflex filament (PLA and ABS wouldn’t stick to the copper apparently).


Found the article via Adafruit’s blog post: http://www.adafruit.com/blog/2014/08/14/etch-copper-circuit-boards-3dprinting-3dthursday/

Anybody at the Hive try it before?
