The main objective of the project is the error-free and low-tolerance production of freeform geometries through the analysis of melt pool dynamics in variable spatial orientations of the melt pool. The gained knowledge will be applied and further developed for the manufacturing of stress-optimized components. In collaboration with the partners of the Research Group, an experimental setup will be designed enabling the reproducible production of components through DED-LB (Directed Energy Deposition with Laser Beam) using wire as an additive feeding material. Besides austenitic wires, martensitically hardenable wire materials are also being investigated. The relative motion between the component and processing head is performed by an industrial robot, facilitating the deposition welding process in arbitrary spatial positions. Thus, the initial task involves determining robust process windows and boundaries for material deposition in variable spatial orientations, considering different building strategies for the materials used. Geometry and roughness measurement, combined with immediate subsequent laser processing to reduce roughness, are additional tasks of this subproject.
