Abstract
Off the shelf, universal hinged leg braces are large, awkward looking devices that are often uncomfortable for the user. With the use of 3D printed components it is possible to modify and streamline the traditional leg brace design making it compact, lightweight, and comfortable. A customizable 3D printed orthotic leg brace is presented that provides the user with assisted mobility in addition to an increased degree of rigidity. The 3D printed frame lattice structure of the brace is tailored around the dimensions of the user's leg. The movement assist mechanism consists of dual mechatronic linear actuators mounted on the brace that aid the leg in flexion and extension during the gait cycle. The brace is a lightweight, independently functioning device that will provide increased mobility for the user.
