Well i gues that depends on the heat you can produce with an 3W Laser. I know it is possible to pop a latex balloon, so that makes me wonder, if you use latex based paint like acryl then maybe, probably you have to go a couple of passes, but that is or should be no problem.

I’m mentally exploring the idea of spray painting copper clad with spray paint and drawing traces in the paint with a laser. After the laser, the board is then placed in etchant and the copper exposed by the laser is etched away. I understand this is possible with 20W CO2 lasers by Youtube videos but has anyone explored this with a laser diode? Is the abundant ebay 445nm, 1W laser or the 808nm, 3W laser up for the task paint ablation?
