A prosthetic hand is an artificial device which is designed for disabled people who lose their hands through trauma or congenitally. In recent decades, unaffordable price, high weight and bad appearance of metal-based prosthetic hands cannot meet the requirement of customers. Owing to the development of 3D printing technology, designing sophisticated mechanisms for a life-like 3D printed prosthetic hand is meaningful. In this project, life-like appearance of prosthetic hand is produced by 3D scanning technology. And all the designs are done within the solid hand file generated by 3D scanning machine. Moreover, two prototypes which have four different mechanisms are printed from flexible materials-Tango Plus. Finally, analysis and improvements done on last prototype demonstrate a functional design.
