A prosthetic appendage for attachment to an outer extremity of an amputated limb that is composed of modular elements fabricated by three-dimensional printing. In one embodiment the prosthetic appendage is a leg. The prosthetic leg includes a foot portion and a plurality of modular and three-dimensionally printed limb elements. One of the plurality of limb elements is pivotally coupled to the foot portion and another of the limb elements is configured at one end to receive the outer extremity of the amputated leg. In another embodiment of the present invention the prosthetic appendage is a hand. The prosthetic hand includes a wrist element with one end configured to receive the outer extremity of an amputated hand, a base portion attached to the wrist element and a plurality of modular and three-dimensionally printed finger elements selectively coupled to adjacent finger elements or the base to form prosthetic fingers.

An example method for producing a prosthetic device for a patient includes obtaining imaging data corresponding to a body part of a patient, generating an object model corresponding to the body part based on the imaging data, generating a prosthesis model based on the object model, generating a set of instructions based on the prosthesis model, and executing the set of instructions using a three-dimensional printer, where the set of instructions, when executed by the three-dimensional printer, cause the three-dimensional printer to produce the prosthetic device for the patient.

Prostheses include a terminal device, a back-lock mechanism, a wrist, a limb-socket, and a harness system. The terminal device can be a five-fingered mechanical hand that provides a releasable adaptive grasp, and has independently flexible fingers. The limb socket can be 3D printed using a molded model of a remnant limb. The harness strap can encircle an unaffected limb and is coupled to the terminal device with a cable so that a user can control the terminal device. The harness system can include a 3D printed harness ring that couples to the cable.
