Preparation

Required material:

  • 2 sheets of TroGlass Color Gloss, one with double-sided adhesive tape (available at Trotec)
  •  2 sheets of Alder wood 0.11'' thick, one with double-sided adhesive tape (available at Trotec)
  • Covering material and adhesive tape

Machine used:

  • Speedy 360 flexx
  • 100 Watt with 1.5" lens

For this sample you can use any laser machine from the Speedy Series.

Important:

  • Use the acrylic cutting grid table or the acrylic slat cutting table.
  • Remove one side of the protective foil from the acrylic. Next, leave on the remaining layer of foil to protect the acrylic sheet from getting scratches during handling.

Step by Step

Step 1: Import /create design template

Import our design template into your graphic program and adapt it according to your needs. Remember to remove the protective foil from the side of the acrylic that you want to engrave on.

Step 2: Laser process

Engrave and cut out the design (B) from the acrylic sheet with adhesive tape. For the best results, we recommend using an acrylic cutting grid table or an acrylic slat cutting table. These tables minimize the reflections of the laser beam on the back of the material. Cover the rest of the table and don't forget to remove the protective film from the top side.
Next, cut the outer contour (B) from the acrylic without adhesive tape.

Additional Info:

  • We used the standard laser parameters from Jobcontrol®, which are optimized for speed
  • Thanks to the z-offset, you get a particularly smooth engraving
  • The material parameters used in JobControl® can be downloaded from www.troteclaser.com

Step 3: Post-processing

The material requires no cleaning after engraving and cutting, just remove the protective foil from the back of the acrylic elements that was cut. Remove the cover of the cut-out circles and alternate the positions of the acrylic and wood starting from outside. The combination of the different materials will create a cool effect.


Inspirations

  • If you wish, you can optimize your results by using the "quality" laser parameters
  • The fiber laser of the Speedy flexx will create good results with some darker acrylic
  • The acrylic will become very bright if you use a 1.5" lens to engrave. You can also cut a 0.11'' material with this lens.
