I have a free source for the top layer of Formica type sheet, they are off cuts from making up laminated work surfaces, mostly for shop fitting. The material is less than a millimeter in thickness and quick brittle, but on my 90w laser I cut a couple of 25mm square test tests at 70% power and 40mm/s and it cut very easily, I might well be able to go less power and more speed, but at the moment I don't want to as I'm not sure what the stuff is made of.
If if it turns out to be safe I might use cut out shapes that can then be fixed onto plywood. I make clocks with contrasting backs and fronts and this might be a good use of the material.
Anyway, does anyone know if this material is safe to use?
