Development and Optimization of Interbody Cage Prototypes: From Design to Validation

This three-year project aims to design, manufacture, and evaluate intersomatic cage prototypes made from various materials using SLM (Selective Laser Melting), FDM (Fused Deposition Modeling), and SLS (Selective Laser Sintering) methods. The focus is placed on the design and simulation phase, including modeling of the associated thermal and mechanical effects. Prototypes will be developed using Computer-Aided Design (CAD), and numerical simulations will be carried out to optimize manufacturing parameters. Researchers will concentrate on fabricating the prototypes using these technologies, combined with post-fabrication heat treatments to enhance mechanical properties. A mechanical, physical, and microstructural characterization of the prototypes will then be conducted. In addition, numerical simulations will be performed to optimize the structural and mechanical parameters. Final mechanical performance tests will be carried out, followed by adjustments to the manufacturing protocols based on the results obtained. This project aspires to improve the manufacturing techniques of biomedical implants and to contribute to the advancement of knowledge in the fields of materials science and additive manufacturing processes.
