Inspired by natural porous architectures, numerous attempts have been made to generate porous structures. Owing to the smooth surfaces, highly interconnected porous architectures, and mathematical controllable geometry features, triply periodic minimal surface (TPMS) is emerging as an outstanding solution to constructing porous structures in recent years. However, many advantages of TPMS are not fully utilized in current research. Critical problems of the process from design, manufacturing to applications need further systematic and integrated discussions. In this work, a comprehensive overview of TPMS porous structures is provided. In order to generate the digital models of TPMS, the geometry design algorithms and performance control strategies are introduced according to diverse requirements. Based on that, precise additive manufacturing methods are summarized for fabricating physical TPMS products. Furthermore, actual multidisciplinary applications are presented to clarify the advantages and further potential of TPMS porous structures. Eventually, the existing problems and further research outlooks are discussed.

“…Based on findings in the literature, waviness in cell struts or walls, deviation of strut cross-sectional geometry, thickness variation of strut, strut detachment, rough surface due to powder particles attachment to the surface, voids between printed layers, and microporosity are the most common types of defects reported in 3D printed polymeric lattice structures [59,[73][74][75][76][77][78][79][80][81][82][83][84].…”

“…Based on the fine element analysis, it was observed that the gyroid cylindrical lattice structure (G-CLS) shows improved energy absorption capability in comparison to CLS based on the strun unit cells. Research carried out by Cao et al for G-CLS [50] and primitive cylindrical lattice structure (P-CLS) [51] showed that geometrical defects have a significant impact on the mechanical properties, what should be taken into consideration during analyzing the deformation mode and preparing simulation models. Szatkiewcz et al [52] analyzed the mechanical properties, energy absorption capacity, and deformation models of Gyroid TPMS cylindrical structures.…”

Triply periodic minimal surfaces (TPMS) are structures inspired by nature with unique properties. Numerous studies confirm the possibility of using TPMS structures for heat dissipation, mass transport, and biomedical and energy absorption applications. In this study, the compressive behavior, overall deformation mode, mechanical properties, and energy absorption ability of Diamond TPMS cylindrical structures produced by selective laser melting of 316L stainless steel powder were investigated. Based on the experimental studies, it was found that tested structures exhibited different cell strut deformation mechanisms (bending-dominated and stretch-dominated) and overall deformation modes (uniform and “layer-by-layer”) depending on structural parameters. Consequently, the structural parameters had an impact on the mechanical properties and the energy absorption ability. The evaluation of basic absorption parameters shows the advantage of bending-dominated Diamond TPMS cylindrical structures in comparison with stretch-dominated Diamond TPMS cylindrical structures. However, their elastic modulus and yield strength were lower. Comparative analysis with the author’s previous work showed a slight advantage for bending-dominated Diamond TPMS cylindrical structures in comparison with Gyroid TPMS cylindrical structures. The results of this research can be used to design and manufacture more efficient, lightweight components for energy absorption applications in the fields of healthcare, transportation, and aerospace.
