“…The basic mechanical performances of TPMS porous structures have been systematically studied. Based on the long linear elastic stage, TPMS structures can be applied as energy absorbers [46,102] or impact absorbers [169]. Owing to the mechanical vibration bandgaps, TPMS can also be utilized as vibration isolators [41].…”

“…Among the performances of different disciplines, the mechanical properties were mostly studied, including the basic Poisson's ratio [29][30][31], anisotropy [32][33][34], elastic behavior [35][36][37], yield strength [38], fatigue behavior [39,40], vibration and buckling characteristics [41,42], etc. Similar to other porous structures, TPMS can also be adopted as energy absorbers under compression [43][44][45][46]. Furthermore, TPMS porous structures are widely applied in tissue engineering [47][48][49][50][51] and implant devices [52][53][54][55][56].…”

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.

Three-periodic minimal surface (TPMS) metal porous structure is a new lightweight structure with wide applications in multifunctional structures. In order to study the deformation behavior and energy absorption of different structures, three TPMS samples with Diamond, Gyroid, and Primitive structures were prepared using the selective laser melting technique. Then the compression tests were carried out on the specimens and the obtained results show that the deformation of TPMS is dominated by bending deformation. Among the studied structures, the highest ultimate strength and energy absorption capacity was 186.44 MPa and 54MJ/m3， respectively, which was achieved in the Gyroid structure. The Gyroid porous structure deforms uniformly along the loading direction in a lamellar collapse pattern. The performed analyses show that when the strain reaches 30%, a shear band of 45° relative to the compression direction appears. Failures in the Diamond and Primitive structures first occurred at the cell junction, and the shear band appeared at a strain of 20%. Comprehensive analyses showed that different types of TPMS structures have different deformation behaviors and mechanical responses during compression. The results of this article can be used to design impact-resistant parts in vehicles or implants.

Six triply periodic minimal surface (TPMS) structures are designed, and their static compression behavior is evaluated in this research. TPMS structures are new type of porous structures super material, which can provide better mechanical properties than the traditional lattice structures in the engineering manufacturing field can. Six TPMS structures (Skeletal Diamond, Skeletal Gyroid, Skeletal I‐graph‐wrapped package (IWP), Sheet Diamond, Sheet Gyroid, and Sheet IWP) are actively designed by parameterization, and the relationship between parameter C and the structures’ relative density is obtained using the interpolation method. Six TPMS structures with different relative densities (10%, 20%, 30%, and 40%) are prepared by selective laser melting using Ti6Al4V powder. Static compression tests are conducted to evaluate the compression performance of these six structures. The results show that at the same relative density, sheet structures have better mechanical properties than skeletal structures. A deformation analysis of the compression process reveals that skeletal structures are dominated by layered fractures and sheet structures by overall fractures. An analysis of the overall experimental results further reveals that the Sheet Diamond structure has the best mechanical properties among the six structures, and the Skeletal Gyroid structure has the best mechanical properties among the three skeletal structures.
