Abstract
Selective Laser Melting (SLM) offers new possibilities in part manufacturing and many of these are of big interest for the tool- and die industry. Besides structural optimisation, further SLM-processable materials are currently in R&D focus, as the combination of structural improvements - such as conformal cooling for tooling applications - the use of application-specific materials can further improve the overall part performance. 14 Ni (200 grade) maraging steel is a die steel that ideally fulfills the requirements of the aluminium die casting process. High thermal conductivity, a low thermal expansion coefficient and stability of mechanical properties at elevated temperatures lead to an amelioration of tool performance. The paper presents a general characterization of 14 Ni (200 grade) maraging steel powder and ist SLM processability. A comparison of material properties of additively and conventionally processed 14 Ni (200 grade) maraging steel is shown. The paper finishes with an outlook on further applications for SLM processed 14 Ni (200 grade) maraging steel.
