These need to be etched and then have the remaining copper dissolved using ferric chloride, This is kind of the second level of what I want to try, but is interesting. You need an ink jet printer to print the circuit on the sheets. I wonder if a 3D Printer would work to print the protective layer. I might have to try that. Not really interested in this technique, since if I ever got to this level of complexity I would probably just order the flexible board through a supplier.
Suppossedly White ningaflex sticks to copper. I have not tested it
