How to do laser stone engraving? 

It is a typical laser engraving process, but the material is different. However, we have classified the laser engraving stone into four easy steps.

Preparation

Prepare the type of stone you want to engrave. Before placing it, ensure the stone is clean and free from dirt. If it is necessary, try to clean it first. After that, place it on top of the working table. Try to put it at the centre of the functional area. 

Choose a design

Choose a design, calligraphy, or text you want to engrave on the stone. You can customize the design and direction using stone laser engraving software. After that, set the laser power and speed of the nozzle. Usually, we recommend the average value of these parameters to our beloved customers. Therefore, you can get a general idea of what range of power and speed you should set for what type of materials. The following table highlights the average value, especially for stone.

After you set the power and speed of the laser engraver for stone, now you should check the focus point of the laser gun. Place the red rectangular light on top of the rock where you want to engrave the design. Now, close the enclosure and start the process. 

Finishing

After engraving the stone, the dust and contaminants will remain. Therefore, you may need an additional step for polishing and giving it a good look. 

What types of stones are suitable for laser engraving?

All types of rocks are suitable for laser engraving. But quality may not be similar for all of them. Quality finishing requires a polished and flat surface so that the stone’s surface can not distort the final result. Therefore, a smooth, clean, flat surface provides the best results. However, if you want to engrave a round surface, you can install a rotary attachment or modelling clay. The following types are the most common stones that are widely popular in stone engraving businesses. 

Granite

This stone is the most common and comparatively cheap than other rocks. It consists of 10% to 60% of quartz and feldspar. The higher the quantity of quartz, the more robust and durable stone. Typically, higher quartz granite is ideal for outdoor applications. However, other factors may also alter the quality of the engraving, such as colour, grains, fossils/veins, and composition. 

Slate

This stone is traditionally popular as a construction material. It is one type of natural rock famous for its strength and excellent resilience. These properties make this rock one of the most durable stones for roofing. However, laser engraving increases the beauty of a slate. As a result, you may find these engraved stones in gift and decorations shops. 

Marble

This stone is a metamorphic rock that comes in various colours. Besides, it has a smooth polished finish surface. Therefore, laser engraving on marble stone is highly noticeable. As a result, people love this type of engraved stone as a gift or decoration. 

Ceramics

Bricks and tiles are the most common ceramic materials for laser engraving stone. However, these two ceramics are famous for fundraising, memorials, or decorations. 

Pebbles and Agate

These two types of stones are more beautiful than other stones. However, pebbles are small rounded stones primarily found in rivers and fountains. On the other hand, agate is a typical rock formation that comes with a wide variety of colours. 

What power laser engraves stones?

Depending on the type of stone, we recommend choosing a laser power between 30W and 60W. Although, on marble, granite, or slate, the recommended minimum laser power is 40W. Therefore, you can engrave all stones using the Odin 32 model from Thunder Laser. Besides, the power density and speed can be different, too, based on the material type. Check the second step of the stone engraving process.

Besides, marbles, pebbles, and agates with laser-engraved characters are excellent gift items. Therefore, starting a stone engraving can be a profitable business.
