The laser cutters can cut materials up to 1/4" thick, although with some denser materials, no thicker than 1/8" is suggested. The following is a list of acceptable materials with some recommended settings for various acceptable material, however, exact settings will vary so a materials test should always be performed.
Prohibited Materials
- Lexan
- Polyurethan
- PVC
- Styrene
- Polycarbonate
- Vinyl
- Glass
- Foam Core
- Metal
Use of prohibited materials could result in the material melting to the laser cutter bed or the release of toxic fumes. Due to the severity in risk, cutting prohibited materials will result in loss of lab privileges and possible fines for damages. Please note that the Co-op sells material that looks like acrylic but is made of PVC and styrene.
Acceptable Materials
Generally, speeds below 20 and ppi at 380 are recommended. Please do a materials test to determine the proper levels for your material by trying a variety of levels to cut and etch.
