Description

Abstract
Additive manufacturing methods are applied in various fields of industry because of advantages like rapid production of parts or freedom in design. In most cases materials with a low amount of carbon, e.g. stainless steels, are used for 3D-printing. An important and widely used representative of these grades is the material 1.4404 (316L), which is well established because of an easy processability and good corrosion properties. However, with focus on tooling and wear resistance, materials like 316L are not suitable because of low hardness, strength and wear resistance.
As an alternative, tool steel materials like the 1.2343 or 1.2344 are used, providing a far better hardness and wear resistance. Unfortunately, L-PBF is a complex process with a small process window for these materials. Therefore, the aim of this study is to identify a material composition that offers both, good processabilty and good wear resistance.
