Additive Manufacturing of Metallic Components
The Additive Manufacturing of Metallic Components Division deals with the relationship between material, geometry, process design and the resulting properties of additively manufactured components. The focus lies on the laser powder bed fusion process (L-PBF).
We develop strategies to produce safe and reliable components through the development of adapted processes, the knowledge of essential influencing variables on defect and microstructure formation and the consideration of the thermal history in the build-up process.
Our work not only considers the additive manufacturing process itself, but also subsequent processing steps such as thermal post-treatment, thermal joining and laser surface treatments and the build-up on existing structures (hybrid manufacturing).
