Dear iMechanicians,

I hope this paper is of interest to the additive manufacturing, architected materials, and dynamic impact (high strain rate) communities.

Quasi-static and dynamic mechanical testing on stainless steel 316L cellular geometries is combined with material characterisation techniques to understand the interplay between additive manufacturing process parameters, geometry and mechanical performance (energy absorption, strength). Four architected materials were studied, finding that the geometry had a greater influence on the investigated mechanical properties, relative to the Laser Powder Bed Fusion (LPBF) process parameter sets.
