Compression behavior of lattice structures produced by selective laser melting: X-ray tomography based experimental and finite element approaches

The compression behavior of hollow architectured structures obtained by additive manufacturing was investigated in this work. Two face-centered cubic structures with the same shape and repetitive pattern but different struts and nodes thicknesses were produced using the selective laser melting (SLM) technique. Deformation of the structures under compression was imaged by in-situ and ex-situ X-ray tomography scanning. The initial state of the...
