Abstract Scope |
Additive Manufacturing (AM), both Laser Powder bed Fusion (LPBF) and Laser Blown Powder Directed Energy Deposition (LBP-DED) promise to produce and repair unique, high quality components from aerospace to biomedical applications. However, the underlying physics controlling the melting, solidification, flow and other phenomena are still poorly understood. Many groups are modelling these processes, but more work experimental investigations are required to estimate many of the initial, boundary and material properties. Here, we present two unique in situ and operando LPBF and LBP-DED rigs that correlatively image the process using synchrotron X-ray, optical and infra-red imaging to capture the underly phenomena that control AM. We show how correlative imaging can be used to both inform and validate analytic and computational models of the process for a wide range of materials from bio-ceramics to Ni superalloys to Ti alloys. |
