- About us
The technology stands out mainly as a method to create complex-shape metal parts that are difficult to process using conventional procedures. A metallic powder of a prescribed granularity is spread out on each layer of the model’s printing area and selectively melted using laser. This creates an interlayer bond between the current and the preceding layer; this process repeats itself up to the final shape. This great benefit of this technology is that it enables the creation of any complex structures.
One of the main assets of this printer is a small printing area which enables a relatively low-cost operation, and makes it easier to cover the whole printing platform with parts for printing. This leads to a higher material efficiency. The printer is equipped with one 200W laser device.
