Materials Approved for Laser Cut and Engrave
- Anodized Aluminum (engrave only)
- Coated Metals (engraved only)
- Coated Ceramics (engrave only)
- Fabric (Thick fabric such as Denim and Suede cuts and engrave well while thin fabric can burn easily)
- Glass (engrave only)
- Leather (uncoated/untreated genuine leather)
- Marble (engrave only)
- Matte Board
- Mylar (thinner than 1/16’)
- Laser-safe Rubber (Low odor is best)
Materials NOT Approved for Laser Cut and Engrave
- PVC and PVC-based plastics: which release HCl (Hydrogen Cyanide) gas when exposed to high heat; damages laser optics and motor controls.
- Vinyl: PVC-based plastic that cannot be used in the lasers
- Polycarbonate/Lexan: Can catch fire, cuts very poorly and discolors; Polycarbonate absorbs laser light rather than being cut by it.
- ABS: Releases HCl gas and melts badly
- Polystyrene: Discolors, releases toxic gases
- Polymer Clay: contains PVC which will release HCl gas.
- HDPE (milk bottle plastic): Melts when burned, can damage machines
- Corrugated plastics: These do not cut effectively in the machines.
- Most commercial non-laser rubber produces high levels of hydrogen chloride gas when burned.
- Bare metals used in the laser must be coated with CerMark or similar laser-specific treatment before being engraved. Metals cannot be cut.
- Precious metals cannot be engraved, as the metal coating substance does not bond to their surfaces.
- Foam Core: Contains air pockets and chlorine; is prone to flash fires
- Styrofoam: Air pockets cause flash fires
- Polystyrene Foam: #1 material that causes laser fires. Very unsafe and does not cut well.
- Polypropylene Foam: Melts and burns badly, also causes laser fires.
- Epoxy: Most epoxy coatings will release fumes and are not safe to be engraved or cut. Watch for woods that have been coated or glued with epoxy.
- Coated Carbon Fiber: Coating emits toxic fumes.
- Fiberglass: Though fiberglass can be engraved, it releases resins under combustion that can damage the laser lens.
- Ceramic tile: Tiles must be coated with a paint or laserable coating before being engraved. Lasers are not powerful enough to engrave directly onto plain tile. Avoid oil-based paint coatings.
- Plastic-Coated Fabrics: These can burn or release gases and are unsafe to cut.
