As the process parameters in the LPBF-process influence the microstructure, density and hardness of the produced parts, their influence on the milling process is suspected. For this reason the new maraging tool steel alloy Specialis® has been investigated on its machinability depending on the built parameters. The influence of the energy density, laser power and scan speed in the LPBF-process on the milling process Specialis® is examined. During the milling process the process forces are measured as well as the obtained surface roughness. The results confirm the importance of adjusting the process parameters in the LPBF-process to the finishing process.
