Additive manufacturing (AM) offers a high degree of design freedom compared to conventional manufacturing processes. However, this has not yet been fully exploited for the manufacture of high-quality products in the aviation and energy sectors. BRAVE therefore aims to create an integrated digital framework for optimizing the AM supply chain, and in particular to increase surface quality. On the German side, a camera-based sensor system is to be developed that allows in-situ roughness measurement during the AM process, particularly of internal areas that are difficult to access.
The BRAVE-TUHH sub-project comprises the design and production of test geometries for the roughness investigations, as well as the experimental determination of roughness-optimized process parameters. 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-based melting of metals using a laser beam), as well as the commissioning and functional tests of the modified system. Comparative measurements are carried out to validate the new roughness sensor technology.
