Homebrew PCBs

This is like the second law of thermodynamics - In the end you will
always end up with thermal transfer ;-)

Anyway, if it is more precise then that's good, but you wrote
initially one has to remove the material between traces after cutting
with the laser. Isn't this weeding very time consuming with complex
boards? Isn't there a danger that the trace material is lifted away
too?

I wonder what would happen if you coated the PCB with toner or
stereolithography powder. Could you burn on the pattern and blow away
the remaining dust?
