All you need to know about laser cutting at UNSW Makerspaces!

Laser cutting is a digital fabrication process that uses a thin, focused, laser beam to cut and etch materials into custom designs, patterns, and shapes. This non-contact, thermal-based fabrication process is ideal for several materials, including wood, paper, plastic and leather.

There are two main types of laser cutting technologies widely available, Fibre and CO2. For this module we will be focusing on the CO2 laser, which we use primarily for woods and plastics.

Key considerations:

Is your file curves only? (not surfaces or meshes)

Have you removed duplicate lines?

Have you joined all curves where possible?

So how do you choose which laser cutter to use?

  1. What material are you planning to cut?
    Timber, plastics, cardboard, leather, felt, cork etc. can be easily cut on our Trotec laser cutters
    Cutting metals? The Kern metal laser cutter is the one for you!
  2. How big is your material/design? Take a look to the right at the bed size guides for the laser cutters we have on campus!

Work smart, not hard

Trying to make a laser cut box? Need a custom enclosure for your Arduino Mega? Want to create a custom engraved box for a gift? There's a web app for that: MakerCase

This web app generates laser cut-able files from the specific dimensions you need - feel free to download the file and adjust it with engraves, holes and any other features you may need!

Grinding your gears

If you're in need of any gears for your robotic arm or want more torque out of your small hobby DC motors, use this Gear Generator to create laser cut gears!
