Granite is generally considered the best stone for laser engraving due to its consistent density, durability, and the high contrast it produces when engraved. Black granite particularly stands out as it creates the sharpest contrast, showing white or light gray markings against the dark background, resulting in crisp, clear, and highly visible engravings.
Other good options include marble, slate and pebbles, but granite’s uniform composition and ability to withstand the laser process while producing excellent detail makes it the top choice for professional laser engraving projects.
The results of laser engraving on stone are influenced by many factors, with material being the primary consideration. We have provided reference processing parameters based on our Thunder Laser Bolt and Thunder Aurora machines, using marble and slate as examples.
| Laser source | Material | Marking result | Speed(mm/s) | Power(%) | Blow Type | Frequency(khz) | Bi-directional or not | DPI |
|---|---|---|---|---|---|---|---|---|
| 30w (RF) | Marble | / | 1000 | 40 | low | / | / | 350 |
| 50w (fiber) | Slate | White | 200 | 20 | / | 60 | Double | / |
The key to creating excellent laser-etched stone pieces is having a quality stone engraver. Thunder Laser Machines offer both high quality and high precision, making laser engraving stone an effortless process. Our different series of machines have distinct features that benefit stone etching.
First, our flagship CO2 Nova Series stands out with its higher laser power and a working platform with pass-through doors, making it ideal for those who need precise and high-volume cutting. You can effortlessly process larger stone materials with these machines.
Second, the Bolt Series, also using CO2 lasers, performs custom stone engraving with its desktop-sized format, perfect for enthusiasts. For those seeking higher precision and professional results, the Bolt Pro offers enterprise-level accuracy for laser-etched stone works.
Additionally, the Aurora series, equipped with Fiber Lasers or UV lasers, can etch into stone with high energy, creating deep markings. While primarily designed for metal marking in a desktop format, it’s also commonly used for processing laser engraved stone works like slate.
You can select the machine based on your specific needs! We’re always here to provide professional consultation and service to answer your questions.
Rock engraving requires a careful approach to both image preparation and post-engraving care to achieve the best results.
In the following steps, we’ll cover key techniques to enhance clarity and contrast in your engravings, along with tips on how to preserve your work for long-term durability.
Image preparation is critical for successful photo engraving on stone. Start with high-contrast images but use a lower resolution of 250-333 DPI, as stones’ natural texture makes ultra-fine details difficult to reproduce. You can adjust your image settings by increasing contrast slightly and converting to grayscale, ensuring dark areas will engrave deeply enough while maintaining lighter details. Additionally, consider the stone’s natural texture and color – darker stones often produce clearer photo engravings with better contrast.
After engraving and cleaning off debris, apply a stone enhancer or sealer to enhance contrast and protect your work. You can simply apply a thin, even layer using a clean, soft cloth or brush. Work in small sections to ensure complete coverage, and wipe off any excess after a few minutes to prevent residue buildup. For outdoor pieces, consider using a UV-resistant sealer like StoneTech Professional BulletProof Sealer.
Most enhancers require 24-48 hours to fully cure – during this time, keep the stone in a clean, dry environment away from direct sunlight and moisture.
Laser engraving on stone is a fascinating and rewarding craft that opens up endless possibilities for creative expression. By understanding the right techniques, materials, and settings, you can produce beautiful, lasting engravings that stand the test of time.
Whether you’re creating custom gifts, memorial markers, or decorative pieces, laser engraving provides a unique way to add depth and contrast to stone surfaces. With the right preparation and attention to detail, you can bring your vision to life and make the most out of this innovative technology. Happy engraving!
