Categorization of congruent TPMS by geometric features using manifold learning and clustering

Recent advances in additive manufacturing technology have enabled the use of architected porous materials in several fields of science and engineering. Triply periodic minimal surface (TPMS) structures garner particular interest due to their smooth and regular features that lead to advantageous effective properties for many applications. In this study, five geometric features (tortuosity of the structure, tortuosity of the flow channels, surface area, solid thickness, and channel width) are calc
