Abstract
Triply periodic minimal surfaces (TPMS) exhibit a unique combination of mechanical properties that are
advantageous for structural applications, particularly in flexural bending. In this study, the flexural behavior of
cellular beam structures with TPMS cores was experimentally investigated. Cellular structures with TPMS are
fabricated using polylactic acid via fused deposition modelling (FDM). The specimens, measuring 24 x 24 x 150
mm³, were designed with various unit cell geometries, including gyroid, diamond, and lidinoid types. Samples
were fabricated in three different cell sizes with two different directions. Each sample was subjected to three threepoint pending. Results showed that cell form and size affect the flexural strength of the fabricated cellular
structures.
