Engraving Stone and Ceramic with OMTech: Precision Art with the Power of Laser
Laser engraving on hard materials like stone and ceramic is no longer reserved for industrial workshops. With today’s advanced desktop and mid-range machines, it’s now entirely possible to turn ordinary tiles, coasters, or stone plaques into beautifully detailed art, right from your home or small business.
At OMTech, we provide creators across Australia with laser engraving solutions that can handle not only soft materials like wood and acrylic, but also challenging surfaces like granite, marble, slate, and ceramic. In this guide, we’ll walk you through the fundamentals of engraving these tough materials, show you which OMTech laser engraver is right for the job, and share practical tips to get professional-grade results.
Why Stone and Ceramic Are Ideal for Laser Engraving
Though seemingly unforgiving, stone and ceramic are surprisingly receptive to laser engraving. Here’s why they’re perfect for high-impact design work:
- Highly Durable: Unlike wood or paper, engraved stone and ceramic won’t fade, peel, or wear down — making them excellent for outdoor signage, garden memorials, or keepsake items.
- Strong Visual Contrast: Laser-engraved lines on marble or slate stand out with natural contrast, especially on dark materials, without requiring colour fills.
- Tactile Quality: These materials offer depth and texture, adding a physical dimension to any engraved design.
Which OMTech Machines Work Best on Stone and Ceramic?
While engraving stone and ceramic requires more power than engraving softer materials, you don’t need an industrial setup. OMTech’s CO₂ laser machines offer more than enough wattage to etch these surfaces with precision and consistency.
OMTech 60W CO₂ Laser Engraver (AF2440-60)
With its large 610 × 1016 mm work area and powerful 60W CO₂ laser, this model is ideal for stone plaques, ceramic tile art, and memorial markers. Its adjustable focus and cooling system make it especially suitable for long engraving jobs on hard materials.
Perfect for hobbyists or boutique creators, OMTech’s mid-range line offers 40–50W of power and easy-to-use software compatibility (like LightBurn), letting you engrave detailed designs on marble coasters or slate wall pieces with minimal setup.
A quick note: Fibre lasers are best suited for metals and should not be used for engraving stone or ceramic, as their wavelength is not absorbed well by these materials.
Understanding Your Materials: What Works Best for Laser Engraving
Different stone and ceramic types respond differently to laser energy. Here’s a breakdown of common materials:
Marble
- Best for: Portraits, fine text, logos
- Settings: Lower power (~20–40%) with slow speed
- Tips: Marble is soft and smooth, ideal for intricate engraving. Avoid overburning by using grayscale photo dithering if engraving images.
Granite
- Best for: Memorial plaques, signage
- Settings: High power (>60%), moderate speed
- Tips: Being very dense, granite requires strong output. Multiple passes may be needed for deep contrast.
Slate
- Best for: Coasters, rustic wall art
- Settings: Medium power, fast speed
- Tips: Slate can flake — reduce focus height slightly and avoid overlapping passes.
Ceramic Tile
- Best for: Kitchen art, nameplates
- Settings: Medium power, high speed
- Tips: Glazed ceramic needs less power than unglazed. White tiles with dark engraving produce the best visual effect.
Step-by-Step: Engraving Stone or Ceramic Like a Pro
1. Prepare the Surface
Clean your tile or stone thoroughly. Dust, oils, or coatings can interfere with the laser’s ability to etch the surface evenly.
2. Design Your Artwork
Use high-contrast designs. Vector outlines work well for logos or text, while photo engravings should be processed into dithered black-and-white formats for best clarity.
3. Secure the Material
Use clamps or brackets to prevent movement during engraving — even slight shifts can ruin alignment.
4. Set Your Parameters
No two materials are alike. Test power and speed on scrap pieces first:
- For marble: start with 30% power, 100 mm/s speed
- For granite: try 70% power, 80 mm/s speed
- For ceramic: 40% power, 120 mm/s speed works well
5. Engrave and Clean
Engrave your design, then clean residue with a damp cloth or mild cleaner. A final polish makes the design pop beautifully.

Frequently Asked Questions
Q: Can I engrave on all stone types?
A: Most natural stones — like marble, granite, and slate — are safe for CO₂ laser engraving. Just avoid pre-sealed or resin-coated stones, as the coating may burn or block the laser beam.
Q: How deep can a CO₂ laser engrave into stone?
A: CO₂ lasers etch into the surface rather than cutting deeply. For stone, expect a few millimetres of surface contrast, which is ideal for text, logos, and images.
Q: Do I need to use additives like marking spray?
A: No. On stone and ceramic, the laser itself creates natural contrast without needing sprays or colour fills.
