This tutorial shows you how to enhance the appearance of simple glasses with an individual 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, and some water and a sponge or a spray bottle. To prevent splintering of the glass, apply a paper towel on the surface and moisten it. To improve your results, make sure there are no air inclusions or wrinkles.
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 in a parallel position.
Next, import the PDF file into Corel Draw and customize it as you want. You could also make 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 (see screenshot in the slideshow above).
