Hi Rick,
I must admit that I have put DLP on the side for now because I have
been unable to get consistent results. I bought a LJ2200 as someone
else mentioned a while ago and had no problem modifying it to pass
quite thick boards through, but the printing was not dependably
uniform. Perhaps I'll get back to it another day.
When I have some time, I think I want to try using a laser to strip
paint (resist) off the pcb. The technology is clear cut and certainly
works. I found someone who can sell me a laser that will focus down
to 3 mils (IIRC), and I have a pcb cnc mill to carry it. Someone in
Instructibles described a using two flatbed scanner carcasses to make
a paper cutting cnc laser for <$50 that looks like it would work well
for this application, too.
