Selective Etching of paint

Saw this cool idea on Twitter. He is using a diode laser to selectively etched off layers of paint on a tile. The tile is white and he added 3 layers of spray paint; black, rose gold and green. He then varied the power/speed to selectively etch off the layers.

Not sure if a CO2 laser would be able to do this because of the higher power.


ya, seen some amazing pieces done this way. Seems to take great control of paint layers AND great control of the laser power levels.
