Approved Materials List

Materials Approved for Laser Cut and Engrave
 

  • Acrylic/Pexiglas
  • Anodized Aluminum (engrave only)
  • Cardboard
  • Coated Metals (engraved only)
  • Coated Ceramics (engrave only)
  • Corian
  • Cork
  • Delrin
  • 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
  • Melamine
  • Mylar (thinner than 1/16’)
  • Paper/Cardstock
  • Pressboard
  • Laser-safe Rubber (Low odor is best)
  • Wood


Materials NOT Approved for Laser Cut and Engrave



Plastic:
  • 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.


Rubber:
  • Most commercial non-laser rubber produces high levels of hydrogen chloride gas when burned.


Metal:
  • 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.


Foams:
  • 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.


Other:
  • 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.
