Abstract
The application of the 3D printing and additive manufacturing in making medical devices have become widespread in the last
decades as the opportunity of the technology is rapidly growing. Notably, the Fused Deposition Modeling (FDM) in 3D printing
technique has been applied to develop the ankle-foot orthosis (AFO) with different materials and composites. This paper presents
a new design and simulation results of a novel orthosis using Carbon Fiber Reinforced Polymer (CFRP). The orthosis for ankle foot is designed for rehabilitation of the patient from the foot drop disease. The orthosis’ shape is modelled to support the backside
of the calf. It contributes to the maintenance of the gait cycle. In this paper, two different models of the AFO are compared, namely
articulated and non-articulated. The finite-element analysis is done using the ANSYS software, and the results for equivalent Von Mises stress as well as total deformation are observed and analyzed. Various materials are applied during the numerical analysis,
as well as their combinations are tested
