abstract = {The development of a sample environment for in situ x-ray
characterization during metal Electron Beam Powder Bed
Fusion (PBF-EB), called MiniMelt, is presented. The design
considerations, the features of the equipment, and its
implementation at the synchrotron facility PETRA III at
Deutsches Elektronen-Synchrotron, Hamburg, Germany, are
described. The equipment is based on the commercially
available Freemelt ONE PBF-EB system but has been customized
with a unique process chamber to enable real-time
synchrotron measurements during the additive manufacturing
process. Furthermore, a new unconfined powder bed design to
replicate the conditions of the full-scale PBF-EB process is
introduced. The first radiography (15 kHz) and diffraction
(1 kHz) measurements of PBF-EB with a hot-work tool steel
and a Ni-base superalloy, as well as bulk metal melting with
the CMSX-4 alloy, using the sample environment are
presented. MiniMelt enables time-resolved investigations of
the dynamic phenomena taking place during multi-layer
PBF-EB, facilitating process understanding and development
of advanced process strategies and materials for PBF-EB.},
