Abstract
Laser powder bed fusion is a type of metal-based additive manufacturing method that can be customized for a given material through modification of process parameters, resulting in changes to the overall quality and mechanical properties of the as-built component. Optimal mechanical properties are typically achieved by performing experimental builds of fully dense components with multiple parameter sets and comparing the resulting mechanical properties. Additionally, AM allows geometric freedom that can be utilized to produce structures tailored for energy absorption, such as cellular structures or lattice structures. There is limited previous work of scaling effects on mechanical properties of cellular structures. The first part of this work aims to determine process parameters that result in the best overall mechanical properties of L-PBF manufactured maraging 300 steel. This work then uses the optimal parameters to produce cellular structures scaled both uniformly and selectively to perform mechanical and physical analysis on their response.
