Has anyone used dark color 3D filament printed onto copper clad PCB as photo resist or etch resist? It might be tricky printing PLA directly to copper clad PCB

It might be tricky printing PLA directly to copper clad PCB, but then you could expose the board to UV or etchant to make the PCB traces. Then remove the PLA plastic to expose the copper traces.

- fainpul 1y agoThe toner transfer method uses a similar process and is probably easier. You don't need a 3D printer, but one of those laminating machines instead.
