Understanding Glass Engraving: How It Works
Laser engraving on glass is different from engraving on wood or metal. Glass doesn’t vaporize like wood—it cracks microscopically under heat. That’s why it’s important to use the best settings for glass engraving with CO2 lasers, balancing power and speed to avoid chipping or uneven textures.
Best Settings for Glass Engraving with CO2 Lasers
The following table shows a general guide to get you started. These settings are ideal for a 60W CO2 laser like the Monport.
| Setting | Recommended Value |
|---|---|
| Power | 20% – 35% |
| Speed | 300 mm/s – 500 mm/s |
| Resolution (DPI) | 300 – 500 DPI |
| Number of Passes | 1 (adjust if needed) |
| Focus | Slightly out of focus |
| Air Assist | ON |
Pro Tip: Defocusing the laser by about 1-2mm helps to spread the beam and reduce the chance of cracking.
