Optimizing Lumbar Implants with Functionally Graded Lattices

Created using ChatSlide

This project focuses on the development of patient-specific lumbar reconstruction implants, addressing the limitations of traditional titanium cages. By utilizing gyroid TPMS lattices, the design aims to reduce stiffness and weight. The study employs FEA-driven grading to optimize material distribution in high-load areas, adjusting parameters like cell size and shell thickness. Results indicate that cell size influences stiffness while shell thickness affects mass, leading to improved...
