I'm working on that, with red (only to see it) laser.
Quite good results for the beginning. It melts the ordinary (cheapest) tonner.
I have to solve:
how to coat uniformly with a thin layer
how to burn it, using a CNC machine (used before to drill
holes) = software problem.
how to collimate the beam for more resolution
