I don't think I posted this before, I conducted this experiment several months ago, but want to share it.
using my 3D printer, ive been able to have moderate success using a normal PVC extrusion on a prepared copper surface, and with minimal under cut. under-cut seems to be the least limiting issue. getting the mask on, and with sufficient detail seems more difficult.

Hahaha really nice! Thumps up. Quite creative. Any test on trace-pitch and trace-width thats possibe? Maybe one can improve by melting the plastic by heating the PCB on top of a toaster just to close gaps if they exist..
