Photron Ltd provided an excellent product (FASTCAM SA-Z 2100K) and outstanding technical support for our research group (led by Professor Peter D Lee at the Research Complex at Harwell and University College London). Our group is a core team of the EPSRC Manufacturing Hub in Manufacture using Advanced Powder Processes (MAPP) https://mapp.ac.uk/. Our aim is to gain new insight into powder based processes, such as laser additive manufacturing (LAM), using high-speed imaging.
The Photron camera was used with our custom built LAM process replicator and synchrotron X-rays to take images inside the laser-material interaction zone. This enabled non-invasive observation of the molten pool and defect dynamics during LAM. The very high quality and low noise images taken by the SA-Z only require a minimal amount of image processing to extract the features of interest. We are delighted to partner up with Photron on this exciting piece of research.
