wax?thing is a 3d printer cost a good pile of money, and wont come close to the quality of even simple toner transfer or photo masking which is already cheap and plentiful
If you have a 3D printer, you'd get far better results for a PCB by replacing the extruder head with a drilling head. Then you could mill your own PCBs.
What about using a 3D printer to print the plastic onto copperclad, then using etchant solution to remove the copper? Would the PLA/ABS come off in the solution?
I've seen a few videos on the milling process and they didn't look fine enough to allow for SMD mounting. Maybe I'm seeing the wrong videos?
