Since I finally have my laser engraver almost back together again the way I want it after dismantling it many months ago, and with thanks to my new 3d printer, I finally got around to buying some Trotec laser perspex in Red over White and some Black over White, as well as some laser foil sticker in black over gold to play around with.

These two are on the Black over White perspex and are about 70mm x 29mm

This is the Red over White perspex and is about 100mm x 40mm

This final one is the black over gold sticker sheet and is about 70mm x 29mm

I am still dialing in the correct laser power / speeds to get the optimal result with the materials, but so far its looking promising.
