| Abstract Scope |
High speed in situ synchrotron x-ray imaging in real and reciprocal space is now an established tool for gaining understanding of the laser-matter interaction during a range of additive manufacturing (AM) process. However, replicating realistic build conditions on a beamline remains a challenge. Many of the studies in powder bed are just on the substrate or using a single layer of powder, rather than looking at multi-layer builds. For both powder bed and blown powder experiments, the processing parameters and hence pool size have not always matched the typical values use commercially. This talk will first review the benefits and limitations of using idealised conditions, and then show examples of how some of the limitations can be overcome through second and third generation in situ process replicators that have many of the features of industrial machines allowing multi-layer builds and even multi-lasers coupled with optical and IR imaging. |
