In Brazil, assistive technology devices are available through the public health system. However, custom-made orthoses are complex to produce and require specialized professionals and expensive materials that are not readily available in the Brazilian public health system. This study evaluated the feasibility of producing orthoses to prevent Acquired Drop Foot Syndrome using photogrammetry, generative design, and 3D printing technologies. The critical contribution of this project is to reduce manufacturing costs and increase the accessibility of these devices. A qualitative action research approach was used to conduct this study, involving a hospital where the demands for orthosis were explored and two clinics that employed digital manufacturing for orthoses production. The production process of 3D-printed orthoses was analyzed. Results showed that a prototype for the orthosis was developed using photogrammetry, generative design, and 3D printing technologies. The prototype developed in this project resulted in a highly personalized orthosis meeting patient’s need. This alternative proved innovative, with significantly lower costs than traditional orthoses. It also demonstrated the feasibility of producing orthoses through the fusion of generative design and 3D printing, representing a technological advancement in healthcare. In conclusion, making these orthoses available within the public health system increases accessibility. It optimizes resources, ultimately positively impacting patients' quality of life, a crucial aspect that this research strives to improve.
