dc.description.abstract3D-printing technology allows designers to create customizable and functional prosthetics for amputee patients in need. This study explored the creation of 3D-printed prosthetic fingers that were specifically designed for a patient with a partial hand amputation. Since the patient’s remaining hand maintained a high degree of strength and wide range of motion, a body-powered prosthetic could enable the patient to move the prosthetic fingers with the rest of their hand. On-site visits with the patient and occupational therapist helped establish technical information such as finger measurements and current range of movement, details that were later used to design the prosthesis. The final design aimed to achieve basic grasps, appear near life-like, and be comfortably worn on the hand. 14 prototype iterations and physical models were 3D-printed and tested for durability and functionality. The final design of the prosthesis incorporated a four-bar linkage mechanism system that closed the fingers by flexing the back of the hand. It tailored to the specific needs of the patient and offered them the ability to perform basic functions such holding, grasping, and writing.
