Abstract Scope |
Additively manufactured lattice structures are well-suited for lightweight structural and other multifunctional applications. However, the additive manufacturing process can contribute to various defects in the structures, which can lead to diminished mechanical properties. The small struts that comprise architected materials exacerbate the process-induced variability in mechanical properties, which often takes the form of size- and orientation-dependent strut-level material properties that differ from those of the bulk material. In this research effort, the extent of these strut- and lattice-level property variations are characterized experimentally, and the findings serve as input to process-aware techniques for designing additively manufactured lattice structures with improved properties that are more predictable. |
