Overview

Acrylic is a type of plastic that can be easily cut and formed to be used in many applications.

Safety

ALWAYS keep a close eye on the machine when cutting acrylic due to its flammability.

Two Main Types of Acrylic Sheet

Extruded Acrylic

Created by extruding molten acrylic pellets through a machine.

  • Pros of Extruded Acrylic
    • Cheaper than cast acrylic
    • Better tolerances
    • Easier to bend and form
    • Easier to flame polish edge
  • Cons of Extruded Acrylic
    • Easy to crack
    • Engraving produces grey frost
    • Lower optical clarity when compared to cast (still very high)
    • Less scratch resistant

Cast Acrylic

Created by pouring molten acrylic pellets into a mold.

  • Pros of Cast Acrylic
    • Produces better results when engraving (white frost)
    • Comes in many colors
    • Machines better than extruded acrylic
    • Higher optical clarity
    • More scratch resistant
  • Cons of Cast Acrylic
    • Expensive

Tips

  • Multiple passes may allow cutting of thicker materials.
  • When vector cutting, use masking tape on the backside of the piece to protect against flair up scorch marks as the laser hits the cutting grid.
