Step by step guide

Create a multi-layer sign using different sign making techniques. You can combine engraving and cutting with a multi-layer technique and dimensional lettering. Use backlit with LEDs to put the sign in the best perspective.


Preparation

Required material:

  • Acrylics and Laminates / engravable plastics
  • We used 3 mm, 6 mm and 10 mm Acrylics

Used Trotec Laser:

  • Speedy 360
  • 100 watts
  • 2 inch lens and 2.5 inch lens

Step by Step

Step 1:

Open the file "Multi-layer-sign" file in your graphics software and send it to the laser.  Settings for speed and laser power may vary depending on the machine used.

Black (engraving)

Power: 60 %, Speed: 100 %, Resolution: 500 dpi, air assist on, z-Offset: +1 mm

Tip:

Use reverse engraving to protect your materials from dust and keep them clean.


Step 2:

Red (cutting)

  • 3 mm Acrylics
    Power: 40 %, Speed 0,2 %, Frequency 20.000 Hz, air assist on
  • 6 mm Acrylics
    Vector marking: Power: 10 %, Speed 1 %, Frequency 2000 Hz, air assist on
    Cutting: Power: 95 %, Speed 0,2 %, Frequency 20.000 Hz, Z-offset -2 mm, air assist on
  • 10 mm Acrylics
    Cutting: Power: 95 %, Speed 0,1 %, Frequency 20.000 Hz, Z-offset -3 mm, air assist on

Tips:

  • Use the 2-inch lens for engraving the laminate and for cutting 3 mm acrylics
  • For cutting acrylics of 6 or 10 mm, use the 2.5 inch lens and keep in mind that a good exhaust is
    very important for perfect cutting results when cutting acrylics.
  • Proper preparation is key. Prepare the layers with double-sided adhesive tape, then the
    assembling only takes some minutes.
  • Engraving the baseplate and the laminate helps for the correct positioning.
  • Mounting a top layer on the 10 mm acrylics creates a visual multidimensional effect.
