I mean, do what you want! But I’ll warn you all we once tried to decorate some sugar cookies with the laser and the designs came out kind of cute but the cookies tasted like… the laser cutter. Like, that weird metallic industrial smell? It just PERMEATED. It was incredible, in an awful way. Even the parts of the cookie that you’d think were untouched, somehow tasted like you were licking the bed of the laser cutter. It’s been a few years but it was memorable enough that nobody’s tried a food thing since.
I think I read that glowforge shows people making designs on pumpkin pies, etc on their lasers but when you read their fine print they say if you have a laser for food, never cut anything else on it. keep your food laser separated from your everything else laser.
