Created this icon to put on a laser cut box. Originally I was just going to engrave it but then I thought, if I engrave it deep enough, I can melt shaved crayons bits for more color. This is what I got. Only thing I don’t like about it is the “wet” stain around the crayon bits but that may just because it is draft board.
That’s how the USAF aircraft maintenance guys used to fix their uniforms when they got jet fuel on them. (It leaves slightly darker spots that you can’t get out.) They’d just dunk the whole uniform in a barrel of fuel. Voila, problem fixed.
Nice! In a life before this one, I used to make crayon art. I’ve always wanted to take a crack at print one in the laser to see what would happen, but I haven’t gotten around to it. Previously I would use vinyl, melt the crayons with a heat gun, let it harden about 80% of the way, then peel the vinyl up.
Nice project! Ive had that oil seepage problem. Another solution is to seal the engrave (I use a brush-applied matte acrylic sealer but a spray one should work as well) before melting the crayon. Then you can remove the mask.
After the engrave, try using some sort of sanding sealer. Just paint it right on with a brush. Make sure to get total coverage inside the engrave especially. This has worked really great to keep my resin projects from soaking in.
