Laser Engraving and Cutting


How a Laser Cutter Works

A laser cutter/engraver works by burning or melting a hole or slot in material. The heat comes from the infra-red light of the laser. The designer chooses the path the laser follows and its power setting to make cuts and patterns. For a more detailed explanation see ESAB Education.

Examples of Laser Cutting and Engraving

Put in several pictures of what the laser can do.

Bechtel Center's Trotec Speedy 400 Flexx Laser

- Dual laser: a 130W CO2 laser and a 60W optical fiber laser
- Bed size 39.5" long X 24" wide X 12" tall
- Metal cutting is very limited, "paper thin" sheets only (please see a TA if you are wanting to cut metal)
- Some materials up to 1/2" thick can be cut (please check our materials sheet)
- Please note that there will be a slight taper to cut edges depending on material thickness.

Cutting considerations:

(tested on 1/8" acrylic, values will vary depending on material)

  • Typical "kerf" of the beam : approx 0.017"
  • Typical dimensional accuracy : +0.005"/-0.01"
  • Smallest space between lines : 0.03"
  • Suggested minimum space between lines : 0.06"
  • Typically a 2 degree taper to most cut edges. (Taper will increase with material thickness typically)
