In situ experiment for selective laser melting — •Jan Rosigkeit, Peter Staron, Florian Pyczak, and Martin Müller — Institute of Materials Research, Helmholtz-Zentrum Geesthacht, Germany

We are currently developing a new industry-relevant sample environment purposefully designed for time-resolved in situ selective laser melting (SLM) studies using high-energy (30−200 keV) and high photon flux (up to 10¹² ph/s) synchrotron radiation. The high photon flux combined with a new fast-acquisition-time (4 ms) 2D-detector for high photon energies permits time-resolved in situ structural analysis of the selective laser melting process. The high-energy synchrotron-radiation based X-rays result in small scattering angles (<8^∘), allowing large areas of reciprocal space to be imaged with a 2D detector. The device for in situ experiments (FlexiSLM) is planned for use at the P07 High Energy Materials Science (HEMS) beamline at the most brilliant synchrotron radiation source PETRA III at the Deutsches Elektronen-Synchrotron (DESY) in Hamburg.
