I've thought about PCB etching with EDM, I figured it would work ok, but
be a bit slow.
People mill PCBs, that's slow & noisy! At least EDM is quiet.
Considering the small amount of material you need to remove, the results
might surprise you. After all, electricity is a good way of removing
metal. Most of us have screwdrivers or probes with bits missing (usually
after testing capacitors!), that's a good bit of metal removed in a short
time.
I'd be interested in the final result (quality, speed, minimum trace etc),
but I doubt I'll ever make PCBs this way, but I'm happy to keep it in
mind. The info could come in handy for other projects, etching
nameplates, etc.
