| Abstract Scope |
With increasing demand in using additive manufacturing (AM) technologies to produce high-quality industrial products, a better understanding of the underlying phenomena is required. To achieve this, we developed an in situ and operando process replicator (ISOPR) to simulate industrial laser powder bed fusion in a synchrotron beamline. We determined the design based on the build process and experimental constraints, evaluating the trade-offs required. The key design criteria included the capacity to be integrated on a range of beamlines (5 to date), to enable high-speed X-ray radiography and diffraction to capture melt pool dynamics and microstructural feature evolution. We also incorporated a correlative high-speed infra-red and optical imaging, enabling the synchrotron imaging to be used for calibrating surface-based process responses. We conclude that in situ process replication of laser additive manufacturing provides a means to transform the understanding of AM processing and expedite the optimisation of strategies that improve product quality. |
