Follow these easy instructions for personalizing a glass set with a laser engraving system.

Required Materials

  • Tumbler/carafe
  • Rotary engraving attachment
  • Moist single-layer paper towel

Step One: Design

Download a premade template or create your own individual designs and adapt them to the shape of your glasses and carafes.

Step Two: Preparation

Cover the area to be laser engraved with a moist single-layer paper towel. This prevents the glass from splintering during engraving. (Image 1) Then switch the Air Assist OFF to avoid premature drying of the paper during engraving. Make sure that no air bubbles or overlaps are formed when you place the paper towel on the workpiece. This would affect the engraving results.

Step Three: Rotary engraving attachment

For installing and removing the rotary engraving attachment, the laser must be switched off. Insert the rotary attachment into your laser and connect it via the connecting cable on the inside of your machine. Now you can clamp the glass into the rotary attachment and focus on the surface.

Step Four: Software settings

Send the print job to the laser. In the Print dialog, set the positioning to Center-Right. Check the Rotary Attachment options and then enter the height of your graphics and the diameter of the workpiece on the right-hand side. (Image 3) Measure the diameter at the point where you want to engrave your workpiece.

Step Five: Engraving

Tips

  • Waterproof acrylic paint can be used to create a color background for bold and subtle engraving effects. Make sure the paint is non-toxic and rinse the glasses manually.
