Description
Summary:Topology optimisation (TO) and Laser Powder Bed Fusion (LPBF) for the manufacturing of welding jigs used in automotive body shops shows high potential regarding material efficiency, weight reduction, and the integration of additional functions into the metal LPBF jig elements. For conventional series production, steel or aluminium jig elements are manufactured by using water jet cutting and machining processes, such as milling, drilling, and turning. To determine the economic efficiency of the topological optimised jig elements, the manufacturing costs for using LPBF with steel powder is compared to the costs for using conventional manufacturing processes. Based on the results, the application of TO and LBPF for jig elements is discussed.
