Additive Manufacturing (AM) holds great promise for producing complex components with tailored properties in the aerospace, automotive, and medical industries. However, the successful implementation of AM relies heavily on the availability of suitable materials with tailored properties to meet the demanding requirements of specific applications. In 2016 voestalpine BÖHLER Edelstahl GmbH & Co KG started its journey in the world of AM by installing its first AMPO powder production unit. Since then, intensive research focuses on the development and characterization of steels and superalloys for AM processes. Through a systematic approach combining alloy design, powder metallurgy, and advanced characterization techniques, the microstructure and mechanical properties of AM-produced parts will be optimized to enhance performance and reliability. Special emphasis will be placed on understanding the effects of alloy composition, process parameters, and post-processing treatments on the resulting microstructure and properties. The findings of this study will contribute to the advancement of materials science for AM, enabling the fabrication of high-performance components with enhanced structural integrity and mechanical properties.
