TPMSpro: Software for generating B-spline-based triply periodic minimal surface models

Triply Periodic Minimal Surface (TPMS) structures hold significant potential in engineering applications. However, they are typically modeled using tessellated meshes, which limit geometric accuracy and editability. This study presents a reverse modeling framework that integrates MATLAB with Computer-Aided Design (CAD) software to generate B-spline-based TPMS models. Within the developed TPMSpro software package, feature curves are automatically extracted, optimized, and exported as CAD-compatible scripts, enabling batch generation of B-spline curves for constructing high-precision TPMS structures. The resulting geometries can be exported in standard CAD formats (e.g., STEP), enhancing surface smoothness, modeling flexibility, and facilitating downstream engineering tasks. • Propose a reverse modeling framework for B-spline-based TPMS models. • Automate feature curve optimization, extraction, and export in TPMSpro software. • Enables export to standard CAD formats (e.g., STEP, X_T). • Enhance models’ accuracy and editability compared to traditional methods.
