Make a three-dimensional winner’s trophy using a mix of wood and metal and 3-D relief engraving. Learn how by following the steps below…

Materials Needed:

  • Sheet solid wood maple
  • 2 sheets 1/4-inch cast acrylic glass (in different colors: one metallic is recommended)
  • Acrylic glue and tissue
  • Double-sided adhesive tape and dots

  • Power: 40 percent
  • Speed: 10 percent
  • ppi/Hz: 500
  • Passes: 1
  • Air assist: on
  • Z-offset: 2 mm

Scratching:

  • Color: red
  • Process: cut CO2
  • Power: 8 percent
  • Speed: .8 percent
  • ppi/Hz: 5000
  • Passes: 1

Step Four: Design and process relief engraving

Send the files for 3-D wood engravings and the other wooden parts to the laser.

  • Process mode: standard
  • Resolution: 500 dpi
  • Cut line: none

When engraving deeply into wood, it helps to cut the job first and engrave the job afterwards.

Engraving:

  • Color: black
  • Process: engrave CO2
  • Power: 100 percent
  • Speed: 30 percent
  • ppi/Hz: 500
  • Passes: 3

Step Five: Cleaning and assembling

trophy
Clean the two acrylic pieces with a damp cloth. The wood relief engraving can be cleaned best with some water and a tooth brush.

Put the acrylic glue on the engraved ring of the base plate and position the metallic ring on it. Press down firmly and allow the glue to cure.
Put double-sided adhesive tape or dots where the wooden relief will be positioned and fix it.

Take the wooden spacer and apply double-sided adhesive tape on both sides. Position it on the left and the right of the black base plate. Make sure to have a rectangular contact surface so that the trophy stands upright.

Finally, fix the lettering and the corresponding back on the spacers to complete this elegant trophy.
