Lasers are awesome! We will soon add a big CO2 laser cutter (80 W) to our machine selection.

Interesting starting points:


Laserscript LS 6090

Synonyms: DE: Laserschneider, "Lasercutter"
Material: wood, glass, acrylic glass, ...
(list of cuttable & engravable materials;
list of only engravable materials)
Used with: laser exhaust system
Access Requirements: upon personal introduction
Status: awaiting commissioning (do NOT unbox without at least one manager present!)

The laser cutter will only be operated by members who have received a detailed introduction!

Safety Concerns

A laser cutter is a delicate and dangerous piece of equipment and should only run under direct supervision of a qualified user. The machine needs to be supervised even more than the 3D printers, with the operator standing by during the entire duration of a cutting job and being in close vicinity during engraving jobs.

Although the laser beam itself should be certified laser class 1 due to the massive housing and other safety features, the fumes generated when cutting various materials can be harmful to human health (see forbidden materials). A good exhaust filtering system can take care of fumes from the allowed materials but only an outside vent will really remove the smoky smell.

Location Requirements

  • no dust
  • 15 °C ≤ room temperature ≤ 30 °C
  • CO2 fire extinguisher in the area

==> will be moved into the eRoom


  • supervise the entire job when cutting
    • a fire can only be stopped quick enough if you open the lid immediately!
  • stay in close vicinity for the entire job when engraving
  • abort if you see, hear or smell anything out of the ordinary!

Forbidden Materials

  • materials that contain chlorine (Cl) - it's unhealthy and also destroys the machine
    • e.g. PVC ("vinyl", found in most soft plastics and records)
    • artificial leather
    • neoprene
  • materials that contain fluorine (F) - it can kill you and also destroys the machine
    • e.g. PTFE ("Teflon") - very very unhealthy!

→ with some materials it is not clear whether it contains Cl or F. If you are not sure, don't cut or engrave it. If you notice any unusal coloration of the smoke or flame, stop the job immediately!

Possible Materials (Cutting/Engraving)

Check the material settings database to see if and how something has been cut before and please add your experience as well.

In addition, you can check the official list from [Epilog].

  • wood
    • plywood
    • particle board/chip board
    • MDF and HDF are also allowed but will make frequent lens cleaning necessary due to their high glue content
  • acrylic glass/Plexiglass (→ not the cheap polystyrene/Bastlerglas from hardware stores, it welds itself shut after being cut)
    • cast acrylic (GS/gegossen) - "chemically better"
      • very suitable for engraving because the colour changes into a milky version of the original
    • extruded acrylic (XT/extrudiert) - better thickness accuracy
      • very suitable for cutting
      • very suitable for parts that should fit together tightly
      • not as suitable for engraving because there is no colour difference
  • leather, but no artificial leathers that contain chlorine!
  • paper
  • colored card
    • discoloration when "engraving", looks nice
  • cardboard
  • rubber (special kind for stamps)
  • foam
  • fabric

When cutting wood or acrylic glass, a small flame may be observed at the focal point but is not necessarily a bad thing. However, if it burns too much or is still on when the laser beam is already somewhere else, immediately open the cover. Because the laser automatically shuts down, the fire should go out.

Possible Materials (Engraving Only)


The tube and filters need to be replaced from time to time which will add up to several hundred €.

We will need to think of an appropriate user contribution per minute

Metal Cutting

Not many laser cutters can cut metal. You could use a CNC mill instead, or try one of these services:
