MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641050547 A) filed by Easwari Engineering College; Srm Institute Of Science And Technology, Ramapuram Campus, Chennai, Tamil Nadu, on April 21, for 'integrated process-structure-performance optimization of 3d printed tetra chiral lattices.'
Inventor(s) include Sivasankar E; Subash V; Subash V; Mari Venkatesh K; and Elumalai B.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention proposes an integrated process-structure-performance optimization framework for tetra chiral lattice structures fabricated using fused deposition modelling (FDM) with Polylactic Acid (PLA) material. The study focuses on the systematic design of lattice geometries by varying parameters such as node radius, ligament thickness-to-length ratio (t/L), and relative density to achieve enhanced mechanical performance and lightweight characteristics. The fabricated structures are subjected to quasi-static compression tests to evaluate properties including strength, stiffness, and energy absorption. A data-driven approach using machine learning (ML) models is employed to predict structural performance based on design and process parameters. Explainable AI techniques such as SHAP and LIME are integrated to identify key influencing factors, improving model interpretability. Furthermore, multi-objective optimization using NSGA-II is applied to obtain optimal design configurations. The invention provides a scalable, intelligent framework for developing high-performance, energy-absorbing lattice structures for advanced engineering applications."
