Abstract
The use of 3D printing to create transtibial orthopedic prostheses has not been studied extensively, despite the increasing number of injuries in countries experiencing armed conflict. Mechanical metamaterials are being explored to simplify the manufacturing process and reduce costs. These metamaterials use artificial structures to create desired mechanical properties and can be designed to optimize strength and elasticity while minimizing weight. Additive manufacturing (AM) is a promising alternative to traditional prosthetic production methods, as it can create complex geometries necessary for mechanical metamaterials. This study proposes a design for a transtibial prosthesis that allows for autonomous movement without energy consumption. The prosthesis is made from a single material and constitutes a passive system. The design was created using 3D printing mechanical metamaterials and underwent static structural analysis by the Finite Element Method (FEM). A prototype was developed to evaluate the feasibility of employing 3D printing process for manufacturing a transtibial prosthesis based on mechanical metamaterials.
