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!

File Preparation

File Preparation Instructions

  • Place your design in the laser cutting template provided
  • Instructions are provided in the template file
  • Templates are available in Rhino (.3dm), AutoCad (.dwg) or Illustrator (.ai). You can import many file types into these templates (.dxf, vectorised .pdf, .svg etc)
  • There are different templates for each different laser cutting machine, make sure you use the correct template for your laser cutting booking

Work smarter, not harder

Trying to make a laser cut box? Need a custom enclosure for your Arduino? Want to create a custom presentation box? 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!

Lasercut 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!
