Homebrew PCBs

Mark,

Sounds like removal is not an issue.

How liquid tight would the 3D mask be? 

Given that a 3D printer gives us a third dimension to the mask, I wonder
what else can be done with it on the circuit board. What would be very cool
is if the 3D printer could form the traces on a piece of fiberglass. I
recall an old process that could put down fine wire and cover it with glue.

Rick

Rick,

A heated bed is no real problem - I built one that works pretty well. 
But I'm not sure the wax won't stick to the copper directly. 
I  hadn't thought about removing the  plastic. PLA, which is the plastic
I've been using, has only one solvent I know of, Tetrahydrofuran, which you
can get on ebay. Heated Benzene is also supposed to work. However, by
switching to ABS, you can use acetone to dissolve the plastic easily.
