Selective laser melting (SLM) is a powder bed-based additive manufacturing process for the production of metallic, highly complex components. With regard to tool manufacturing for forming production (e.g. extrusion, deep drawing), an almost unrestricted freedom of design enables the integration of cooling channels close to the contour in order to reduce hot spots, so that the component distortion of the semi-finished product is minimized, the service life of the tool is extended and the process time is shortened.
