I don't know if it has been discussed before, but has anyone ever used a 3D printer to deposit a layer of plastic on a circuit board to use as the pattern for etching? It seems to me that this may be an easy way to do this as no extra steps would be needed, just print and etch.
If so, how did it work? And how did they remove the plastic after the etch?
