The mechanical performance of powder bed fused (PBF) components can vary significantly,
even within a single build with processing parameters kept constant. To better
understanding this variability, two sets of uniaxial fatigue specimens were examined,
differing only in gage section surface area and location on the build plate. Significantly
different fatigue performance was observed between the two geometries, despite being
manufactured in the same laser power bed fusion (L-PBF) build. Possible explanations for …
