Software and File Formats

This section will be updated before the laser cutter is available for use with members.


This section reiterates the DOs, DON’Ts, and other policies related to using the laser cutter.


Anyone who wants to use the laser cutter must be trained. No exceptions. Training is by appointment. Drop us a line by email, through Facebook, or on our Slack to get scheduled. Training covers safety, how to use the laser cutter software, procedures when using the laser cutter, and other general tips. It does not cover how to create files suitable for use with the laser cutter. You will also need to sign our laser cutter agreement after taking training.


You are expected to follow the rules outlined during training and to check in with the front desk before using the laser cutter. This is so the front desk can verify your training status and give you access to the laser computer. Failing to use the laser cutter properly and safely can result in being blocked from using it.

If you would like to know if the laser cutter is currently in use, you can check the Confluent status page for usage information on some of our tools.

Allowed Materials

Anything not on this list is forbidden. Contact Confluent by email, Facebook, or in person during open hours if you’d like to discuss other materials. Please have a copy of the material’s MSDS available.

** Warning: There are many modern floor coverings known as “linoleum” which are nothing like the original. Lasering them is hazardous to your health and the machine. See the “where to buy” page to get the real thing.

Forbidden Materials

Anything not on the allowed list is to be considered forbidden unless Confluent has otherwise given explicit permission on a case by case basis. This list is therefore not to be taken as complete or all-inclusive.

  • Polycarbonate
  • PVC
  • HDPE (“milk jug plastic”)
  • Polystyrene foam (“Styrofoam”)
  • Polypropylene Foam
  • Fiberglass
  • Carbon Fiber
  • ABS (ex: LEGO, some 3D printer plastic)
  • MDF

Many of these are hazards. They may melt instead of cut, catch fire, or could also release toxic gases. It is in the best interest of your own health to follow these rules.

DO NOT cut materials which are too thick. See the next section.

Material Thickness

The table below is the maximum nominal thickness allowed to be cut on the laser cutter for the listed materials. If your material is too thick, use one of the saws in the shop instead. Materials over these thicknesses can still be engraved.

Material Maximum Thickness
Acrylic ??″ (~?? mm)
Delrin ??″ (~5 mm)
Plywood (Wood) ??″ (~6 mm)
Bamboo ??″ (~6 mm)
Glass 0″ (this machine can only etch and engrave glass)
Metal 0″ (this machine can only etch and engrave coated metals)

If your material isn’t listed, ask first instead of just trying it. The harder a material is the thinner the maximum thickness will be.
