The laser cutters can cut materials up to 1/2" thick, although with some denser materials, no thicker than 1/8" is suggested.  We have two tables with suggested settings for Vector Processes and Engraving Processes on acceptable materials, however, exact settings will vary so a materials test should always be performed. The settings provided should be used only as a reference, since they are settings previously used by our team, but won't necessarily work the same way with your own material.

Also take into 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.

These are only suggestions: Every type of material will react differently with the laser, even from one plastic to the next. Use these settings as your starting point then adjust one variable at a time until you achieve the result you desire. Settings for any material are a matter of personal preference. Not every material that can be run at high speed should be run at high speed. A better mark can often be achieved by slowing your laser and giving the laser longer to react to your material.

Review the Prohibited Materials listed on the Laser Cutter Policies page before purchasing or cutting material.

Vector cutting table (cross-hatched) must be used. A general rule of thumb for cutting acrylic is to relatively slow speed and high power; this produces a more flame-polished edge.

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.

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.

Recent incidents of fire indicate that this material requires caution and additional supervision if cutting is attempted. Additionally, glue and air pockets may prevent complete cut-through in some areas.

Engrave only. Must be painted. Not magnetic. Ask for assistance from the Tech Desk when etching this material. Use low power and high speed. Blue paints are more difficult to remove. If the finished product has a shadow, use alcohol or lacquer thinner to clean the edges. This material can be tricky: if it's polished before being painted, you'll see a polished finished product. If the brass isn't polished before being painted, the result will be dull.

Engrave only. Must be painted. Magnetic. Ask for assistance from the Tech Desk when etching this material. Use low power and high speed. Blue paints are more difficult to remove. If the finished product has a shadow, use alcohol or lacquer thinner to clean the edges. This material is steel that has been coated with brass, that brass layer is polished, then a layer of lacquer is applied, then the paint is applied. When you etch it, you're exposing the polished brass that is protected from oxidation by the lacquer coating. This material is preferred over painted solid brass.

To dissipate heat from the engraving process, use either a wet sheet of newspaper/paper towel or a thin coat of dish soap.
