Combine the various techniques for processing wood to create a unique wooden sign.

Materials Needed

  • Solid wood alder
  • Solid wood walnut
  • Double-sided adhesive film

Step One: Design

Download a premade template or create your own design, using black to indicate engraving, red for scoring, and blue for cutting. (Image 1)

Step Two: Tape

Affix a double-sided adhesive film to one side of the walnut board.

Step Three: Laser Processing

Using a 120-watt laser with a 2-inch lens, set the following parameters:

Laser Parameters for Alder:

Engraving (Black): Power: 15%; Speed: 20%; 500 ppi; Air Assist: On; Z-offset: +1mm

Scoring (Red): Power: 5%; Speed: 1%; Frequency: 1000 Hz; Air Assist: On

Cutting (Blue): Power: 64%; Speed: 0.8%; Frequency: 1000 Hz; Air Assist: On

Laser Parameters for Walnut:

Engraving (Black): Power: 60%; Speed: 30%; 500 ppi; 4 Passes; Air Assist: On; High Quality

Cutting (Red): Power: 100%; Speed: 1%; Frequency: 1000 Hz; Air Assist: On

Cut out all the elements from the various wooden boards. (Image 2) For the cups in this example, assign the “Relief” process option. Use the standard process option for the rest.

Select Optimized Geometries and Inner Geometries first for better results.

For the relief engraving, make sure that the job is not places over the joint of the two glued wooden boards because the laser cannot erode the glue.

Step Four: Assembly

Remove the protective film of the adhesive on the parts and stick them in the appropriately marked positions on the base plate. (Image 3)
