The laser cutters can cut materials up to 1/2" thick, although with some denser materials, no thicker than 1/8" is suggested. The following is a list of acceptable materials with some suggested settings for various acceptable material, however, exact settings will vary so a materials test should always be performed. (The settings provided below should be used only as REFERENCE, since they are settings previously used by our team, but won't necessarily work the same way with your own material).
Also take in consideration that due to natural variations in the pressure of the vacuum, it is expected that the laser cutters might lose power over the day. For example, If you cut something in the morning, it might need a little more power if you cut again in the afternoon.
Prohibited Materials
- Lexan
- Polyurethane
- PVC*
Styrene
- Polycarbonate
- Vinyl
- Glass
- Foam Core
- Foam board
- Metal*
Chloride-based materials
Questionable Materials - Consult with Tech Desk Staff for approval
Wood, ie. plywood with potentially flammable adhesives
Soft materials like leather
Reflective materials
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 do a materials test before every new cutting session to determine the proper levels for your material

| Acrylic | 1/8" (3 mm) | 12 | 100 | 100 | 100 | 40 | 100 | *Suggested setting from Epilog manual Note from manual: Adjusting the standard focus distance so it is closer to the lens by about .080” (2 mm) will produce better edge quality when cutting 1/4” (6mm) acrylic and thicker. Two passes can be used for cutting thicker materials. There are two types of acrylic: cast is better for engraving (it creates a frosted look when engraved) and extruded acrylic produces a much better flame polished edge. |
