The optimal approach for reliable metal part production and prototypes

The selective laser melting system SLM® 280 HL provides a build chamber of 280 x 280 x 350 mm and a powerful double/multi laser technology. The SLM® 280 HL dispenses with the F-Theta optics and puts on a 3-D scanning optics. This improves not only the laser beam profile but also the quality of components.
