Topology optimization, design, and characterization for the use of different biomaterials in orthesis manufacturing by additive manufacturing method

Orthoses are devices used to enhance the structural and functional features of the neuromusculoskeletal system. Despite orthoses made in different sizes, they cannot address the exact varying anthropometric requirements due to their standardized dimensions. Typically, orthoses are used in temporary injury situations and discarded when the need for them diminishes. Traditional orthoses, constructed using non-biodegradable materials, contribute to environmental pollution by becoming plastic waste. Therefore, there is potential in employing additive manufacturing methods to create orthoses that perfectly fit an individual's body measurements and possess biodegradable features. In orthotic usage, it is desired to minimize the weight of the orthosis while ensuring the necessary strength. High-density plastics add weight to orthoses, while the use of low-density plastics results in ergonomically disadvantaged structures. These reasons provide opportunities for the utilization of new biomaterials in orthotic production. This research aims to develop innovative orthoses through topology optimization, design, and characterization for the use of various biomaterials in orthotic production using additive manufacturing methods. The goal is to expand the limits of orthosis utilization by incorporating biodegradable materials, enhancing user experience, and reducing production costs. This study aims to investigate how to improve orthotic user comfort, contribute to the country's economy and industry by lowering production costs, support sustainable production, and facilitate the localization of medical products.
