From May 12 to 15, 2025, Louis Becker and Prof. Sebastian Weber from LWT attended the final conference of the Priority Program 2122 "Materials for Additive Manufacturing" in Hanover.
The program (https://www.uni-due.de/matframe/) funded by the German Research Foundation (DFG), aimed over two funding phases -each lasting three years- to research and further develop new materials and modified powders for powder bed-based additive manufacturing. LWT participated in the program throughout its entire duration with two different projects.
In the first funding phase, LWT collaborated with the Chair of Materials Testing Technology (WPT) at TU Dortmund and the Leibniz Institute for Materials Engineering (IWT) in Bremen to investigate the additive manufacturing of tool steels using powder blends.
In the second funding phase, LWT worked closely with the Institute for Applied Powder Metallurgy and Ceramics (IAPK) at RWTH Aachen. The joint research focused on the additive manufacturing of high-nitrogen steels by adding silicon nitride (Si₃N₄) to corrosion-resistant steel powders.
As part of the conference, Louis Becker (left in the photo) and Mr. Radtke from the Institute for Applied Powder Metallurgy and Ceramics (IAPK) at RWTH Aachen (right in the photo) presented the joint research results.
We sincerely thank the German Research Foundation (DFG) for funding this forward-looking project, as well as all participating researchers for their dedication and excellent collaboration within the framework of the priority program.
