Laser engraving on wood

Wood: ecological and elegant

Wood is known for its warm and natural appearance. It brings a touch of elegance to any space and has the ability to create cozy environments. It is a noble, durable and timeless material, which offers ecological advantages as a sustainable resource because it is biodegradable and recyclable.

Like most materials, wood can be engraved, and CO2 laser engraving is the most effective technique.

Laser engraving wood

Basically the system uses a CO2 laser to vaporize or burn the surface layer of the wood, thus creating precise and detailed engravings, with high definition and high quality.

Two types of laser engraving on wood can be highlighted:

  • Pyroburned or burnt type
  • Embossed engraving


Burn-type engraving or pyrography is one in which the CO2 laser strikes in a linear manner, “burning” the surface to be engraved in a controlled manner, leaving it darker. This creates a “fire” engraving effect, where only the drawing remains darker or blackened. As it is controlled by computer, you can engrave the wood with the desired drawing. The effect is very aesthetic and is a good alternative to screen printing or painting wood.

Embossed engraving

Embossed engraving (high or low) is the one in which the CO2 laser eliminates superficial layers of the material to leave the drawing to be engraved in relief with respect to the original surface (raised, in the case of high relief, or lowered, in the case of low relief). Unlike other engraving techniques, laser engraving offers greater precision and finer details.

Wood is an ecological and elegant material that offers endless possibilities for engraving. The CO2 laser engraving system will help us obtain the desired results on wood in the most effective way.

Things to keep in mind when laser engraving wood

  • The color of the wood can influence the contrast and visibility of the engraving. For one thing, lighter woods, such as maple or spruce, can provide a strong contrast for dark engravings. On the other hand, with darker woods, such as walnut or mahogany, the engraving could be a color more similar to the wood, generating a less strong contrast. Additionally, the color of the wood can change with time and light exposure, which can affect the appearance of the engraving in the long term.
  • The hardness of the wood contributes to the quality of the engraving. Hardwoods, such as oak, walnut, cherry, or maple, produce cleaner, more detailed engravings. Soft woods, such as pine or cedar, produce less precise engravings due to the lower density of the wood.
  • Wood grains are visible patterns in the wood that mark the direction in which the fibers of the tree grow. They are formed due to the annual growth process of the tree and represent the growth rings. Each tree has its own grain pattern. These can vary the uniformity and depth of the engraving, significantly affecting the final result. For example, in soft woods the grain can be harder than the wood itself and can cause variations in the engraving. This can also occur if the grain is very pronounced or irregular.

Taking these aspects into account and making adjustments to the laser, the desired results can be obtained.
