Computational Characterization of Functionally Graded Porous Absorbers Based on Triply Periodic Minimal Surfaces (TPMS) [PDF]

Proceedings of the 10th Convention of the European Acoustics Association Forum Acusticum 2023, 2023
Triply periodic minimal surfaces (TPMS), a class of periodic implicit surface with zero mean curvature, are emerging as an excellent solution to create graded porous structures. The grading of a porous layer can enhance and broaden the acoustic absorption in a target frequency range.

Triply Periodic Minimal Surfaces (TPMS) for the Generation of Porous Architectures Using Stereolithography [PDF]

, 2020
A new generation of sophisticated tissue engineering scaffolds are developed using the periodicity of trigonometric equations to generate triply periodic minimal surfaces (TPMS). TPMS architectures display minimal surface energy that induce typical pore features and surface curvatures.

An Overview of Additive Manufacturing of Triply Periodic Minimal Surface (TPMS) Structures. [PDF]

Polymers (Basel)
Triply periodic minimal surfaces (TPMS) are mathematically defined minimal surfaces that exhibit zero mean curvature and repeat periodically along all three Cartesian axes. They integrate mathematically defined geometry with extensive functional adjustability. Their smooth, non-self-intersecting topology enables systematic control over relative density
