The present master dissertation examines the optimisation of a biomedical 3D printed implant study. The finite element method (FEM) is used to discretise the model of an implant made from a human shoulder blade (scapular). Simulations are performed using the Computer-Aided Design (CAD) software Siemens NX, specifically the NX Nastran solver. This work is intended to reduce implant mass and create a personalised geometry that considers the anatomy of the patient. Topological optimisation (TO) is employed, and Ti-6Al-4V is chosen as the implant's material. The different operating conditions, manufacturing constraints, and application of forces/loads at points where bone stress is applied are studied. Next, the design goal is established, which is to reduce the mass in order to allow tissue regeneration. The results show the distribution of the material. When the results are displayed, the redistribution of the material is visible, and then the lattice structure is added. Later, the printing simulation was conducted where the overlapping layers are simulated using the Direct Energy Deposition (DED) 3D printing method. Unfortunately, the real object was not able to be 3D printed.
