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

, 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.

Flow Characterization in Triply Periodic Minimal Surface (TPMS)-Based Porous Geometries: Part 1—Hydrodynamics

Transport in Porous Media, 2022
The modeling of flow and heat transfer in porous media systems have always been a challenge and, the extended Darcy transport models for flow and equilibrium and non-equilibrium energy models for heat transfer are being used for macro-level analysis, however, the limitations of these models are subjected to porous geometry.

Computation of Implicit Representation of Volumetric Shells with Predefined Thickness

Algorithms, 2021
We propose and validate a method to find an implicit representation of a surface placed at a distance h from another implicit surface. With two such surfaces on either side of the original surface, a volumetric shell of predefined thickness can be ...

Implementation of triply periodic minimal surface (TPMS) structure in mesenchymal stem cell differentiation.

, 2022
Abstract Tissue engineers have recently been interested in triply periodic minimum surfaces (TPMSs) for use in creating biomimetic porous scaffolds. Improved cell attachment, migration, and proliferation may be achieved with TPMS scaffolds because of its many benefits, such as a high volume to surface area ratio, reduced stress concentration ...
