Based on using laser micro welding of any type of metallic powder such as stainless steel, tool steel and alloy steel, LaserCUSING ® - fusion of single-component metallic powder materials - allows the layer-by-layer construction of components from almost all metallic materials (e.g. stainless steel and hot work steel powders). Metallic powder is hereby fully fused layer for layer to produce a 100% component density. A specially developed exposure strategy allows the generation of solid and large-volume components without any deformation. A patented surface post-treatment process directly after the construction process ensures the highest surface quality and hardness. Countless technical refinements such as automatic powder evacuation, a separately developed coating system and a circulating inert gas atmosphere make the M3 linear a machine concept in a class of its own.
