How Does Laser Engraving Stone Work?
The laser beam works by instantly increasing the temperature of the surface of the stone. Due to the high temperature, the color on the surface of the material changes, or a layer of the surface are removed, leaving a visible mark or tangible depth, depending on the power.
What Type of Laser Engraver Can Engrave Stone?
A CO2 laser engraver is a preferred option for engraving stone. Due to its wavelength, it can be easily absorbed by stone, making it an ideal laser to engrave stones.
Can a Diode Laser Engrave Stone?
A diode laser engraver can also engrave stone. Diode laser engravers are usually less powerful than CO2 laser engravers, but they can also engrave stone, and they are more affordable.
The commonly available diode lasers have a blue light and an optical power of 10-40W. If you need better, faster, and darker engraving, you can go for one above 20W.

Advantages of Engraving Stone Using a Laser Engraver
There are other ways of engraving stone, such as drilling. However, a laser engraver is the best option for stone engraving. Let’s discuss why.
1. No Wear and Tear
The first benefit of laser engraving is no wear and tear. Engraving with drills and chisels is quite difficult, and mostly, people end up damaging the object.
If you are doing it with your hand, it is quite difficult to control the force. There can be cracks and other wear and tear on the object. Even if you are using a CNC drilling machine, there are chances of wear & tear because there is physical contact.
When you engrave a stone with a laser engraving machine, there is no physical contact made between the machine and the object. Therefore, there is no wear and tear on the object.
2. Quick Results
Laser engraving machines are very fast. They engrave stones in no time.
If you are using a powerful machine, such as the xTool F1 Ultra, then the speed can be up to 10,000mm/s or more, depending on the type of the machine and the optical power. The engraving can be done in one only pass without any pre and post treatments.
3. Incredible Accuracy
The accuracy of laser engraving machines is phenomenal. It does not matter how fine the details are; the machines are very accurate. Their sturdy design, positioning sensors, and accurate motors keep the engraving as accurate as possible.
With some laser machines, the accuracy can be up to 0.0004 inches, which means you won’t see any errors or defects. The repositioning accuracy can be up to 0.0007 inches. Therefore, the laser returns to the same point if needed, and there won’t be any noticeable error.
4. Intricate Designs
Using CNC drills and traditional methods, you cannot engrave very intricate designs. Due to the physical contact, the object can be damaged if the design is too small and intricate.
However, with a laser engraving machine, you can engrave without any worries. The laser spot of the machines is usually smaller than 0.10 x 0.10mm. You can engrave any type of design, irrespective of its complexity and size. The laser machine will offer perfect results.
5. Waste-free Process
There is almost no or very little waste when you engrave stone using a laser. Mostly, the laser marks stones and does not remove the material. But even if it removes some material, it will be very minimal.
