Individuals with hemiplegia or hemiparesis often require the use of orthoses. The aim of this study was to develop an orthosis for the lower limb using digital modeling and three-dimensional printing. Three distinct designs were created. The orthotic models were developed using Inventor software and printed with the Elegoo Neptune 4 Pro printer, using ePA-FC filament. Finite element simulation was carried out using SolidWorks software. According to the simulation, the orthosis design and the material used in the 3D printing process meet mechanical resistance requirements, as the von Mises stress value (55.9 MPa) remained below the material’s yield strength, which is 140 MPa. The orthosis was found to be well-suited to the patient’s anatomical and biomechanical features. Overall, the device demonstrated good functionality, usability, and user experience. However, certain aspects can still be improved.
