Homebrew PCBs

Wow - Nice link. It seems like that would do it! Now if you used a 
copper  solution to put down traces instead of resist, you would 
really have something! Now that I'm about done with DLP, I could 
easily get interested in this    project! All of the systems we are 
using in this group waste a lot of copper, and an additive system 
rather than a subtractive (etching or cnc routing) would be great. I 
know that a lot of work is being done on this, but the ability to 
drop a singe dot where you want it would let us do a lot of experimental work.
