Additive manufacturing (AM) offers high design freedom compared to conventional manufacturing processes. However, this has not yet been fully utilized for producing high-quality products in the aerospace and energy sectors. BRAVE therefore aims to create an integrated digital framework to optimize the AM supply chain, with a particular focus on improving surface quality. 

On the German side, a camera-based sensing system will be developed that enables in-situ roughness measurement during the AM process, particularly for internal, hard-to-access areas. The subproject BRAVE-TUHH includes the design and fabrication of test geometries for roughness investigations, as well as the experimental determination of process parameters optimized for roughness. Subsequently, components will be developed that enable the integration of the light-field camera as a sensor in a PBF-LB/M system (powder bed fusion of metals using a laser beam), as well as the commissioning and functional testing of the modified system. Comparative measurements will be performed to validate the novel roughness sensing technology.
