Scanner Method For Modeling and Manufacturing of 3d Printable Upper Limb Orthosis

The study aims to design and manufacture orthosis using the programming process instead of the common traditional method in manufacturing orthosis, which requires several steps, more cost, time, and less accuracy. This work makes a new design of orthosis for patients with wrist drop deformity due to radial nerve palsy, by using a different method in the formation of the 3D model, where several images were taken over the patient’s hand, and then processed by (meta shape) program to produce the 3D model of the hand. After processing the 3D model of the hand, the new design of the orthosis was created using the mesh mixer program relying on the 3D model of the patient’s hand and then printed through the 3D printer from polylactic acid. The presented and discussed results show the new orthosis is comfortable, and light, contains ventilation enough for the skin, and has enough strength to prevent mechanical failure.
