Abstract
— Upper-limb amputations significantly impacts an individual's ability to perform daily activities. Therefore, the scientific community offers relief through prostheses. By utilizing benefits of 3D printing technology and compliant mechanisms in creating cost effective devices, this study aims to design a 3D printed hand prototype using a 3D printer with the dual-extrusion feature to provide compliant fingers, which were evaluated through nonlinear stress analysis FEA. It was found that the finger model that presented the ideal characteristics was the model with leaf-shaped joints, 2mm in thickness and ABS finger segments. The model was then printed and subjected to three simple grip experimental tests with various shapes and a given weight of 250g wherein it was able to successfully perform all trials.Keywords
