Subject: RE: 3-D printer resist application? (was: Re: [Homebrew_PCBs] Anyone milling PCBs?)

For many 3D printers its simpler to print a Dremel or other mini-drill mount for the printer and use it to mill a PCB…

But then you have to deal with the fumes from burning paint.

I doubt it would be fine enough. That said are people doing 3D-ish printers where they print the traces instead using that silver conductive paint or similar, so who knows.

People have tried to print either the resist or traces directly onto copper board with inkjet printers with little success.

Mark (?) on this list managed to laser print directly onto copper which surprised me.

I've been meaning to try the 'spray board with paint and laser it off' method. Diptrace will export a file suitable for milling (isolation traces) that will work for lasering. Should be fairly simple and fast, certainly quieter than a mill.
