But to do it right, you need the proper setup, the right engraving machine, and a clear understanding of glass as a medium.

In this guide, we'll show you how to configure your laser engraver for flawless glass results, explore which machines are best for the job, and share real-world applications of glass engraving in everyday life. Whether you're a hobbyist or a growing business in Australia, this guide will help you get started on stunning laser projects with confidence.

 

Best Laser Engravers for Glass Projects

Not all lasers are suitable for glass engraving. While glass is widely used in design, it requires a specific type of laser to engrave safely and effectively.

1.Use a CO2 Laser

A CO2 laser is ideal for engraving on glass. The infrared wavelength (~10.6 μm) of a CO2 laser is absorbed by the glass surface, creating a frosted, textured look. This type of laser doesn’t cut into the glass but gently etches it, giving you control and precision without the risk of shattering.

We recommend exploring our CO2 laser machines for glass engraving. These machines are designed to work with non-metal materials like acrylic, wood, leather — and, most importantly, glass.

2.Mid-Range Options for Home or Business

If you're looking for a balance between size, power, and affordability, OMTech's mid-range laser engravers offer the perfect solution. These machines are great for:

• Personalised glass gifts
• Drinkware engraving
• Small-run commercial glassware
• Decorative home signage

With intuitive controls and powerful CO2 capabilities, these machines provide flexibility for both hobbyists and small business owners across Australia.

 

Basic Setup and Key Tips for Glass Engraving

Even with the right engraving machine, your success with glass depends on the way you prepare and operate your laser engraver. Below are key steps and tips to help you get clean, professional results:

Machine Setup

• Use Low Power + High Speed: Glass is sensitive to heat. Start with lower power (10–20%) and higher speed to avoid cracks and chips.
• Check Your Focus: Make sure your laser is properly focused on the surface of the glass to avoid blurry or uneven engraving.
• Masking Technique: Apply a damp paper towel or masking tape over the engraving area. This reduces heat stress and helps prevent shattering or flaking.

Engraving Tips

• Avoid Tempered Glass: It’s heat-treated and more prone to breaking when laser-engraved. Use float glass, crystal, or borosilicate glass for best results.
• Clean the Surface First: Dust or oil can interfere with the engraving. Wipe the surface with alcohol or a glass cleaner.
• Always Test First: Try your design on a scrap piece or inexpensive item before engraving the final product.
• Proper Ventilation: Glass engraving produces fine dust and fumes. Always use your exhaust fan or filtration system for a safe workspace.

These best practices will help you get the most out of your OMTech laser projects, ensuring your final product looks clean, polished, and ready to display.

Common Questions

Q: What is the best kind of glass for laser engraving?

A: we recommend using non-tempered glass types such as float glass, borosilicate glass, and crystal glass for laser engraving. When looking at glass for engraving, you can also look for glass that is marked "laser-compatible" to show the manufacturer is confident it can be used in lasers.

Q: Can I control the depth of the engraving?

A: Of course! You can control the intensity and texture of the mark by adjusting the laser’s power, speed, and number of passes. At OMTech, we recommend using lower power settings and higher speeds to achieve a clean, frosted finish without chipping.

Q: After I engrave the glass, how should I clean it?

A: After engraving, gently clean the glass non-abrasive glass cleaner and lint-free cloth. If you used masking tape or paper towel during engraving, remove it carefully and clean the surface to reveal a smooth, finished result.
