Learn how to create beautiful laser cut glass edges when using acrylic engraving material. Having a good down draft is crucial when creating intricate pieces, such as jewellery.


Required material:

  • Needle nose pliers

Check out our entire range of laser engraving materials here.

Machine used:

  • Speedy 400
  • 120 watt
  • 2.0" lens
  • Acrylic cutting grid table

You can use any laser machine from the Speedy laser engraver series or the SP laser cutter series for this application.


  • We have used a darker coloured cast acrylic for this application.
  • When creating a glass edge it is important to have a nice down draft. This makes laser tape (painter tape) an important tool.

Step by Step

Step 1: Import /create design template

You can use the template we have provided, or alternatively, you can create your own stunning necklace charm. The laser parameters may vary depending on the material used.

Print settings:­

Process mode Resolution Cut line
Standard 500dpi None
Halftone Other
Colour None

Step 2: Laser process

We recommend using the acrylic cutting grid. Place the material onto the laser bed and ensure that the remaining area is sealed with tape. This will increase the exhaust power, which in turn will create a better down draft.
