      abstract     = {The additive manufacturing process Laser Powder Bed Fusion
                      (LPBF) has developed into series production in some areas,
                      e.g. in turbomachinery construction and medical technology.
                      Due to industrialization, there is also an increasing demand
                      for the LPBF process for spare parts and small series in the
                      tool industry in order to increase service life or shorten
                      development times. Compared to conventional production, the
                      integration of internal cooling channels or the use of
                      lattice structures for light weight in conjunction with
                      greater geometrical freedom are keys to the manufacturing of
                      complex individual special design tools for the tool
                      industry. It can therefore be deduced that the material
                      selection for the LPBF process must be extended to include
                      other tool steels. High-alloy, carbide-containing,
                      abrasion-resistant tool steels such as high-speed steels are
                      particularly suitable for use as cutting tools. However,
                      high-alloy tool steels tend to crack during processing by
                      LPBF due to internal stresses. In this work, the
                      processability of high-speed steels is investigated using
                      HS6-5-3-8 as an example based on different LPBF process
                      designs. The aim is to fundamentally investigate the
                      influence-effect relationships between LPBF process control
                      (preheating temperatures), system technology (preheating and
                      inert gas control), component number and component height,
                      and chemical composition on the resulting defect density,
                      microstructure and component hardness of HS6-5-3-8. The
                      developed process control is to be used as a starting point
                      for the manufacturing of a technology demonstrator. There
                      maining challenges in processing high-speed steel HS6-5-3-8
                      by LPBF will be presented. The successful processability
                      (large component density, crack-free specimens and
                      homogeneous microstructure) when using pre heating
                      temperatures ≤ 450 °C can be demonstrated.},
