This study explores the mechanical properties of porous structures derived from 15 triply periodic P-surfaces (TPS(P)) originally modeled on zeolite atomic frameworks. Elastic characteristics were computed for representative volume elements (RVEs) of these surfaces, revealing significant variations in elastic moduli and pronounced anisotropic behavior. From the RVEs of the most mechanically robust structures, larger-scale architectures were fabricated using PLAþ material via additive manufacturing (AM). These specimens underwent thorough mechanical characterization, integrating numerical simulations with experimental tests, including load curve analysis. Computational predictions showed strong alignment with experimental data. A key finding is that some structures exhibit compressive strength surpassing that of the base material, underscoring the exceptional load-bearing capacity of these engineered porous structures.
