Recommended Materials

Material Comment
Acrylic Cuts well. Turns into combustion byproducts immediately!
MDF Mostly turns into smoke. Ash may be an issue. Use air assist to clear the ash.
Laser Rubber Ash may be an issue. Use air assist to clear as much ash as possible.
Acetal Plastic Apparently works if the plastic has additives.
Leather Cuts / Engraves.

Banned Materials

Material Comment
PVC Combustion byproducts are literally hydrochloric gas. Do not cut.
