[EE] Making PCB prototypes with laser engraving machine?
Edson Brusque
this looks *very* interesting:
What about using it to make prototype PCBs?
Best regards,

"It can engrave on Acrylic, Bamboo, Ceramic Substrates, Cloth, Coated Metal,
Composites, Cork, Corian, Crystal, Delrin, Fabric/Denim, Fiberglass, Foam,
Glass, Kevlar, Laminated Plastic, Leather, Marble, Plastic, Paper, Rubber,
Wood, Stone, etc. Cannot engrave stainless steel and metals."
Oh well.

But maybe it is possible to use one of the things it can engrave as a
resist.
Polyurethane or something else that comes in spray cans perhaps?

If you are planning to use chemical etching, it is a lot cheaper to use
normal photoresist.

People who should know say that experiments in that direction
have not been very successful:
http://www.instructables.com/forum/EYXONSMRFGEUOJJOS2/
They also say that importing these cheap laser machine from
china is very "iffy", since they're not adequately certified
for sale in the US (there's currently a contest with a US-built
laser machine a a prize. Those seem to run about $6k for mid
sized units.)

rather like the Versalaser device. I have been looking at getting a
Versalaser for our lab, but am told it would have difficulty taking copper
of the surface of laminate, to make PCBs like the LKPD milling unit does.
The laser is just not powerful enough, and fro engraving metals, there needs
to be a coating it can evaporate to make the pattern.
The UK agent for the Versalaser sent me a PDF brochure, where they have
"engraved" the company name on a chocolate log, already for presenting on
the table ...
Just the tool for doing "high powered" presentations ...

What about using laser to form conductive alloy that has been printed on
fiberglass ? ( melt tin and silver together ? )
