Porous structuresmanufactured using selective lasermelting (SLM) have beenwidely used in fields such as tissue engineering,
aerospace, and automobile. SLM-built gyroid structures made in stainless steel 316L has superior properties such as good
corrosion-resistance, good biocompatibility, good self-supporting performance, and excellent mechanical properties. In this
study, gyroid structures with different sizes were modelled and manufactured using SLM. Then the mechanical properties of the
structures under quasi-static compression loads were investigated. The elastic moduli and yield stresses of the structures were
calculated from stress-strain diagrams which was obtained by conducting quasi-static compression tests. Moreover, to estimate
the discrepancies between the designed and the as-produced gyroid structures, an optical microscope was used to observe
their micromorphology. Results shows that sizes of the as-produced structures were larger than their CAD (Computer-aided
design) sizes, and the elastic moduli and yield stresses of the structures were improved as their thickness values increased. The
process of compression failure shows that 316L gyroid structures manufactured using SLM has good toughness.
