Laser marking wood and bamboo

Laser marking processes on wood

Laser marking on wood exploits the concentrated power of a laser beam to engrave or mark the surface of the wood. This process takes place through the absorption of laser light by the material, which generates enough heat to alter its surface. The three main methods of laser marking on wood are engraving, ablation and carbonization.

Engraving

The engraving technique creates a permanent marking by removing a thin layer of the wood. This is ideal for creating fine details and legible texts.

Ablation

In this method, the laser completely removes a thin layer of wood, creating visual contrasts and a distinctive look. It is often used for decorative purposes.

Carbonization

Carbonization harnesses the heat of the laser to create a dark contrast on the surface of the wood. This technique is particularly suitable for marking on light woods.

Other organic material applications

In addition to wood and bamboo, which are certainly the most common, the CO2 marking laser is also optimal for engraving leather and fabrics. It can create geometries, logos, and complex designs with very high precision. The engraving in this case is done by burning and the edges can also be cut at the end of the process. In this case, the laser finds space in the world of Fashion and Furniture.

The CO2 laser

The CO2 marking laser is a versatile and widely used technology in the field of industrial marking. This type of laser exploits a gas composed mainly of carbon dioxide (CO2) as an active medium to generate the laser beam. One of the distinctive features of the CO2 marking laser is its wavelength of about 10.6 micrometers, making it particularly suitable for working on non-conductive materials such as wood and bamboo. CO2 laser marking is valued for its accuracy, speed and ability to generate high quality permanent markings, contributing significantly to product traceability and identification in industrial production.
