Prohibited Materials
Do not laser any of these materials, especially anything with chlorine (Cl).
Material | Notes | Consequence |
---|---|---|
ABS | Possible death. Releases cyanide gas and will likely catch fire. | |
Coated Carbon Fiber | Noxious fumes. | |
Fiberglass | Noxious fumes and can't be cut. | |
HDPE | Catches fire. | |
Polycarbonate/Lexan | PC absorbs IR light. | Cuts poorly and can catch fire. |
Polypropylene Foam | Melts and catches fire. | |
Polystyrene Foam | Catches fire. | |
Polyvinyl Chloride (PVC) | Includes vinyl, artifical leather, etc. | Possible death and destroys laser. Releases chlorine gas which quickly corrodes optics and metal machine components. |
