Basic rules for the Trotec Speedy 400 Flexx laser cutter/engraver

  • If you don't know what the material is, then don't cut it. It can poison you, cause a fire, or damage the laser system
  • You must have previously completed the badge on passport for the laser cutter (proof will be required to use the laser)
  • A BIDC TA must be present during the setup of the laser. Incorrect setup leads to poor cutting and engraving
  • Do not tamper with any safety system on the laser or you will be asked to leave. Laser beams move at the speed of light - you cannot dodge them as in films
  • You must clean up after you have finished
  • Ask questions if you need help
  • Please review the videos below before coming in to work on your project

Trotec Speedy 400 Flexx Laser

  • Both a 130W CO2 laser and a 60W optical fiber laser
  • Bed size 39" long X 24" wide X 12" tall
  • Metal cutting is very limited, "paper thin" sheets only
  • 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)

Pre-approved materials:

  • Plywood, balsa, softwoods, hardwoods
  • Acrylic
  • HDPE - tends to melt for sheets thicker than 1/8"
  • Cardboard
  • Cotton fabric / felt / genuine leather
  • Paper / cardstock
  • Poster board / foam board
  • Trotec brand materials
  • Uncoated metals

Consult with the TA on:

  • Coated metals
  • ABS
  • Carbon fiber
  • Any material containing carbon, zinc, chloride due to potential fire or poison
  • Polycarbonate or Lexan - often produces poor results
  • Any materials not listed elsewhere

Pre-banned materials:

  • Any unknown material - you must know what you are cutting
  • Materials containing bromine - usually anything flame retardant
  • PVC
  • PET
  • Vinyl
  • Fiberglass
  • Polystyrene / polypropylene foam
