Abstract Scope |
Innovation in Laser Powder Bed Fusion (LPBF) of metals is happening across the entire manufacturing process. Manufacturing parts consisting of multiple metals is a promising approach to improve functionality and performance in many applications, including high-performance heat exchangers in future fusion reactors. Selective Powder Deposition (SPD) is a technique in which a single deposited layer consists of a 2D pixelated pattern of powder, enabling three-dimensional control over the material distribution. In this work, Belgian company Aerosint’s SPD recoater is integrated into a 3D Systems ProX 320 LPBF machine. Whereas literature mainly focuses on thermo-metallographic studies of material interfaces, here attention is given to machine design and the influence of SPD process parameters on powder deposition. This camera vision-based study will contribute to multi-material LPBF by giving calibration procedures, as well as insight into deposition dynamics, resulting in informed design guidelines and identification of key limitations. |
