Today, balsa wood is one of the most widely-used materials in the model making branch. Due to its light weight and high degree of mechanical strength, it is ideally suited for model aircraft in particular. But there are a whole series of less well-known technical applications that also make use of these material properties.
Benefits of laser processing:
Contactless processing so no breakage, not even in the finest of details
Only very low laser power required
No chipping waste, less cleaning required
Less material waste

Balsa wood is a material that is ideally suited to processing with laser. The laser beam makes it possible to cut and engrave extremely filigree details in the material in one work step. Due to its very low density, this wood can be cut quickly and chiplessly with a very low laser power of 30 to 100 Watts. In addition, material damage caused by clamping or tool contact is prevented. The fibre direction has no effect on the quality of the cut.
The fibre direction has no effect on the quality of the cut. If optimum results are to be achieved, the raw material must be stored in a dry place before processing in order to keep the moisture content as low as possible. This results in an imperceptible browning of the cut edges.
We recommend the following systems for the processing of wood:
The name ‘balsa’ derives from Latin and means raft, because balsa wood was originally used for building rafts. Balsa trees are fast growing flowering plants that are cultivated in plantations in the vicinity of tropical rain forests in the northern part of South America and then felled when they are between 5-7 years old.
An exceptional property of this wood is its light weight combined with a relatively high structural strength. In addition, balsa wood is very pliable and elastic making it an ideal material for processing.
