Approved Lasercutting Materials

The following table shows which materials are safe to cut with a laser. Some materials are dangerous to cut and can release toxic fumes or can catch fire!
Note: Material dimensions must be less than 20”x12”.

Wood Most untreated hardwoods, softwoods up to 1/4” thick (1/8” is recommended). Thin plywood is ok but does not cut as well due to glue layers.
Plastics Acrylic (cast or extruded) up to 1/4” thick (1/8” recommended), Mylar sheets
Rubber Laser engravable rubber only
Cellulose Chipboard, Paper, Cardboard
Fabrics Most thin natural fabrics (no wool or leather due to fumes)
Glass Etching only, cannot cut
Metal Painted or anodized aluminum (engraving only, cannot cut)
BANNED MATERIALS Food, Chlorinated plastics (PVC), ABS, Rubber, Vinyl, Foam, Treated Wood, Galvanized Metal, Fiberglass, Mirrors

 


Suggested Lasercutter Settings

The following table shows suggested lasercutter settings for various materials. If the laser power is too low or the laser moves too fast, it won’t cut. If the laser power is too high or the laser moves too slowly, it can scorch and even set fire to the material. Quite often settings will need to be adjusted due to variations in material manufacturing, as well as fluctuations in laser power. We always recommend testing laser settings on a piece of scrap if possible. If you have suggestions, please contact us at makerspace@chipublib.org!

Note: These settings are for the Full Spectrum 45 Watt H-Series CO2 lasercutter.
