The effect of design parameters on the mechanical performance and energy absorption behavior of additively fabricated triply periodic minimal surface structures

Abstract In this study, the mechanical performance of triply periodic minimal surface (TPMS) structures under compression load, which are widely used in biomedical applications, was systematically investigated. The aim of the study was to compare the mechanical strength, energy absorption and surface-to-volume ratio of structures fabricated with different TPMS types (diamond, gyroid, primitive), volume fractions (40%, 60%, 80%) and layer thicknesses (0.10 mm, 0.15 mm, 0.20 mm) to determine the o
