Woodworking lasers are perfectly-suited for laser engraving and laser cutting wood and timber, such as toys, decorative items, artistic craftwork, souvenirs, Christmas decorations, gifts, architectural models and wood inlays.
When cutting and engraving wood and timber with the laser, high processing speed and clean edges are particularly important. Woodcutting lasers produce a clean laser cut and accurate edges, even when working on highly complex object shapes and sizes. Time consuming and difficult cleaning processes are eliminated, as no chips are produced when cutting or engraving wood or timber with the laser.
In the cutting clearance of the material, the laser will generate a temperature increase that is higher than the sublimation temperature of wood. The 'suddenly evaporated'—in other words 'sublimated'—wood is visible in the form of smoke escaping at a fast rate. This smoke also transports the introduced heat away from the wood. Consequently, there is only relatively low thermal stress on the material near the cutting clearance. By accurate focusing, selecting the appropriate optics and supplying compressed air, high-quality cuts on wood can be produced, and the cutting edges, with their brown colour, can often be used effectively in the design.
Since wood is a natural material, the laser user must consider various characteristics, such as the density and resin content of each individual type. Soft woods, like Balsa wood, require a lower laser power and can be cut at a higher speed. Hard wood, as an example of dense wood types, on the other hand, requires a higher laser power. When working with MDF, which consists of glued wood fibers, we recommend the use of compressed air.
