From March 24 to 26, 2026, the 5th Symposium on Materials and Additive Manufacturing will take place in Kassel. The conference, organized by the German Materials Society (DGM), combines manufacturing and materials-related aspects of additive manufacturing and will be held in hybrid format.

Leibniz-IWT is represented with numerous contributions from various departments. The lectures and posters cover current research topics such as heat treatment and microstructure evolution in laser powder bed fusion, in-situ alloying of iron-based shape memory alloys, process optimization for titanium and aluminum alloys, gas atomization of amorphous metal powders, and modeling of nitrogen transport in additive manufacturing of martensitic steels.
