This tutorial will show you how to enhance the appearance of simple glasses with a custom engraving for weddings and other special events.
- Rotary attachment
- Champagne glass
- Paper towel
- A sponge or a spray and some water
Trotec laser used
- Speedy 300
- 80 watts
- 2.0 inch lens
Use a 2 inch lens instead of a 1.5 inch lens to prevent cracking in the glass.
To mount the rotary attachment and plug it in, the laser has to be switched off. After that you can switch on the laser and put the prepared glass into the rotary attachment.
To prepare the glass you will need a paper towel, some water and a sponge or a spray. To prevent the glass from splintering, apply a moist paper towel to the surface. The easiest way to do this, is by using a sponge or a spray. Make sure that there are no air bubbles or wrinkles in order to get a perfect result.
Put your prepared glass into the rotary attachment and make sure that it is firmly attached. If your glass is conical, adjust the inclination angle until the surface you want to engrave is positioned parallel to the worktable.
Import the PDF file into Corel Draw, customize it as you like or take your own design and send it to the laser. Make sure that you have activated the rotary attachment and entered the diameter of the glass in the properties dialog.
