The laser cutting and engraving system are in BIDC229 – Prototyping
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
- 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.
(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)
- Plywood, balsa, softwoods, hardwoods
- HDPE - tends to melt for sheets thicker than 1/8"
- Cotton fabric / felt / genuine leather
- Paper / cardstock
- Poster board / foam board
- Trotec brand materials
- Uncoated metals
Consult with the TA on:
- Coated metals
- 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
- Any unknown material - you must know what you are cutting
- Materials containing bromine - usually anything flame retardant
- Polystyrene / polypropylene foam
