Laser Cutting

Laser cutting is a process that uses a laser beam to cut or engrave materials. The machine is computer-driven, based on design data generated by the user. Industrially, powerful lasers can cut thick metals. In the Product Realization Lab, our lower powered machines are designed to work with thin plastics, woods, and paper materials.

Complex 3D forms can be assembled from flat-pattern designs. Many students use SolidWorks and Adobe Illustrator to generate design data. Additionally, a useful free program is Autodesk’s 123D Make, which can generate slices to cut and form a solid model.

  • Acrylic (mirrored, textured/frosted, opaque, transparent)
  • Duron
  • Some Hardwoods (Black Cherry, Pine, Poplar, Walnut, Ash, Maple, Basswood)
  • High-quality Birch plywood
  • Corrugated cardboard
  • Felt
  • Matboard
  • Chipboard
  • Silicone
  • Cork
  • Various papers
  • Foam core
  • Cotton fabric
  • Anodized Aluminum (etching only!)

The following materials are NOT allowed on Room 36 laser cutters:


  • Any hardwoods NOT explicitly listed above
  • Polycarbonate
  • PTFE
  • Delrin
  • Carbon fiber
  • Transparency sheets
  • Camera gels
  • Polypropylene (HDPE, LDPE, etc...)
  • Polyethylene
  • Styrene
  • Laser-engravable rubber stamp material

See a TA if your material is not listed!! Do NOT assume that it is allowed.
