Current prosthetic hand devices remain highly expensive and unaffordable for the majority of upper extremity amputees, especially in developing countries. With regards to finger amputees, there remains a lack of effective prosthetic solutions to aid in the performing of daily activities involving the grasping of objects. 3D printing offers an alternative development pathway for prosthetic hand devices with the potential to both lower the cost and increase the accessibility of these devices for finger amputees, without sacrificing functionality. This project focuses on the design and prototyping of a low cost, 3D printable, mechanical prosthetic hand device for individuals with multiple finger amputations, whom have at least one finger remaining. The device is designed to allow finger amputees to utilize the motion of a remaining finger to yield a grasping motion in the prosthetic fingers. With the incorporation of 3D scanning, this device can be customized for each patient.
