The art of laser engraving stone a technique also known as stone laser marking or stone laser etching. It involves the precise utilization of laser beams to etch intricate designs, text, or images onto various types of stone surfaces, such as marble, granite, and slate.
Stone laser engraving is always the better choice among all methods of stone engraving as it offers precise and durable engraving on various types of stones, providing intricate designs with lasting quality.
In this comprehensive guide, we delve into stone laser engraving, exploring its working process, required machine, suitable stones for laser engraving, and the preparatory steps needed before starting the engraving process.
In this article:
Part 1: What is Stone Laser Engraving and the Machine?
1. How Does Laser Engraving Work on Stones?
Stone laser engraving works by directing a focused laser beam onto the surface of stone, which causes localized heating and vaporization of the material.
This process removes a thin layer of stone and creates the desired engraving, such as text, graphics, or patterns and this method offers precision and versatility, making it ideal for various applications such as personalized rock accessories or paintings.
2. Stone Laser Engraving Machine:
To begin laser engraving stone , particularly on stone plates or slabs, you'll require a laser engraving machine. These machines are indispensable for stone laser engraving, as they can handle the hardness and density of stone materials, streamlining the engraving process and ensuring precise and durable results.
With numerous laser engraving machines available, some people may wonder What laser is best for engraving rocks or what laser engraving machine is best for stone engraving?
Actually, both Diode and CO2 lasers are ideal for engraving stones. However, if you prioritize portability, convenience, and cost-efficiency, Diode laser engravers are the preferred choice.

Step 4: Set up the Stone Laser Engraving Machine
Firstly, Make sure your engraver is powered on, and then connect your laser engraver to your computer or mobile device using the appropriate interface (USB, Bluetooth, etc.)
Secondly, Open the graphic design software and load your design.
Thirdly, Turn on the "Preview Mode" to confirm if the laser lens is correctly focused. To verify it, you have 2 methods.
If you choose LaserPecker 4 (LP4), the first method is to use a ruler to measure the distance between the slate slab surface and the machine, with a recommended distance of 15cm or 150mm.
Alternatively, you can achieve the correct focal length by judging whether the two red dots emitted by the machine overlap. This ensures precise focusing for optimal engraving results.
Fourthly, You need to place the items within the designated working area and examine the design's appearance on the slate slab. If it doesn't fit correctly, you'll need to adjust its position and size to ensure it aligns with the dimensions of your project.
Finally, Access the software's laser settings to adjust parameters like power, speed, and resolution according to the stone slab's properties and design intricacy. You might be wondering, "How much laser power is needed to engrave stone slab?" and "How deep is the laser etch on stone slab?" Rest assured, I've got you covered!
To get the best result, the recommended laserpecker 4 material settings for stone slab is 2 W 1064 nm; Resolution: 2k; Power: 100%; Depth: 10%; Pass: 1
