Abstract

Selective laser melting (SLM) is a metal additive manufacturing process that shows significant advantages in manufacturing lattice structures. In this paper, a novel surface-based square origami structure made of a nickel-based superalloy was fabricated using SLM. Three different wall thicknesses (50, 75 and 100μm) were used to examine the manufacturability and corresponding compressive behaviour of the manufactured lattice components. Finite element analysis (FEA) was conducted to determine the uniaxial compression and then verified by quasi-static compression testing. The results showed that the components with thinner walls more easily folded and buckled than those with thicker walls, indicating that higher densification strains and energy absorption values may be achieved with thinner walls, although the thicker walls were stronger and could withstand larger loads. This research offers insights into the design and manufacture of advanced lattice structures by providing an improved understanding of the compressive behaviour of surface-based square origami structures.
