In this study, the bending behavior of different TPMSs (Triple Periodic Minimal Surface Structures), which have potential for biomedical applications and are fabricated using additive manufacturing, was investigated. Five different TPMS geometries (Primitive, I-WP, PMY, FRD, and Fischer-Koch S) were fabricated using a bio-compatible resin with an mSLA-type 3D printer and subjected to a three-point bending test in accordance with the ASTM D790 standard. The flexural performance of the specimens was evaluated based on the first peak force and maximum force values. The obtained results indicate that geometric differences are significant in flexural strength. The I-WP structures exhibited the highest strength with first peak values of 8.42 N and maximum force values of 9.17 N. The PMY structures have reached values close to I-WPs but have been found to be advantageous in terms of energy absorption by exhibiting more ductile deformation. The Fischer-Koch S structures, on the other hand, have exhibited average flexural strength and balanced deformation performance. In contrast, FRD and primitive structures exhibited low flexural strength and experienced early loss of stability due to brittle fracture behavior. The results indicate that I-WP and PMY geometries are particularly suitable for biomedical implant and bone implant designs, PMY structures are useful in energy absorption systems due to their ductility, and Fischer-Koch S structures are applicable in engineering applications requiring balanced deformation. This research has revealed the critical effect of TPMS geometry on mechanical behavior and demonstrated the importance of geometric selection in application-oriented designs.
