Acrylic Valentines Day Necklace Charms

Laser cutting acrylic allows you to create stunning glass edges. By combining laser tape and an acrylic laser cutting grid table you will create a nice down draft, which plays an important part in creating glass edges when laser cutting acrylic.


Materials required:

  • 1 sheet of 3mm thick acrylic
  • Laser tape
  • Necklace chain
  • 6mm jump rings
  • Needle nose pliers

You can purchase a wide range of different laser acrylics from our engraving supplies webshop

Laser machine used:

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

To create these charms you can also use other Speedy Laser engraving machines or SP laser cutting machines


  • In this sample we used cast acrylic.
  • To create a more elegant look, we chose a darker coloured acrylic.
  • When creating a glass edge it is important to have a nice down draft. Which makes laser tape (painter tape) an important tool to have.

Step by Step

Step 1: Import /create design template

When creating your necklace charm you can use our template or create your own stunning design. Please not that the parameters will differ depending on your laser machine, available power and the chosen material. 

Print settings:­

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

Step 2: Laser cutting

As mentioned we recommend using the acrylic cutting grid table for laser cutting acrylic. Place the material onto your laser and seal off the rest of the laser table with tape. This will increase the exhaust power creating a better down draft.
