Laser Compatibility
LASER INTERACTION
Safety: DANGER — NEVER LASER ASA.
Fumes: ASA (Acrylonitrile Styrene Acrylate) releases acrylonitrile (carcinogen), styrene (probable carcinogen), and acrolein on burning.
Warning: ASA is UV-stable ABS with the same toxic combustion chemistry. The acrylate component adds additional hazardous breakdown products. Never laser ASA.
