I’m about to cut my first puzzle on the Glowforge Plus. After printing the photo, I’m using a product called Fusion 4000 to attach the image to book board using a hot press, a process we use a lot for making our handmade books. Fusion 4000 is designed to be used with hot presses at 160 degrees. I wasn’t sure if it would be okay to cut through it with the laser, even though it’s sandwiched between the paper and board, so I contacted the company who makes it, D & K. They have sent me a data sheet which shows no hazards with “normal” use, though I don’t imagine laser cutting would be considered normal use.Old Fusion 4000 - Now send letter.pdf (99.4 KB)
I’ve attached their spec sheet here which indicates the composition of the material: Polyethylene, Copolymer of ethylene and acrylic acid, Copolymer of ethylene and vinyl acetate, Copolymer of ethylene and butene-1, Silicon Dioxide.
What do you think? Safe or not?
