This paper presents a study case on the structural topology optimization of biomedical wrist orthosis. The manufacturing process integrates photosensitive resign that enables production of geometries that are both impact-resistant and exhibit a smooth, refined surface finishing which is essential for biomedical applications. The 3D printing is based on Digital Light Processing (DLP). Based on extensive biomechanical studies for accurate simulation parameters, four loading cases were defined for topology optimization. Maximam stresses and displacements were considered at upper limits for the optimization problem with weigh reduction.
