| Abstract Scope |
Hybrid integration of Laser Powder Bed Fusion (L-PBF) with Rotational Friction Welding (RFW) enables the manufacturing of complex assemblies. However, RFW is conventionally restricted to cylindrical geometries due to strict coaxial alignment and chuck-clamping requirements, limiting its applicability. This study presents a semi-automated parametric workflow for generating custom holding structures that allow non-standard geometries to undergo RFW. Implemented in a graphical programming environment using implicit modelling, the workflow analyses input geometry and generates a structure. To take full advantage of additive manufacturing (AM) capabilities, the structure incorporates an internal lattice infill, reducing material usage, manufacturing time, and thermal artifacts associated with large solid L-PBF builds. The workflow was validated by generating a holding structure and successfully performing RFW on a non-circular geometry. This work demonstrates a scalable path toward hybrid L-PBF-RFW fabrication of complex components.
