Prosthetic leg comprising three-dimensionally printed elements

A prosthetic appendage for attachment to an outer extremity of an amputated limb, comprising:

• a base element wherein the base element forms a foot structure to support walking upon the prosthetic appendage;
• a plurality of three-dimensionally printed modular limb elements forming a protrusion at a first end and forming at a second and opposing end a recess to receive the protrusion from an adjacent three-dimensionally printed limb element;
• a sphere;
• a first three-dimensionally printed modular limb element having an end pivotally connecting to the base element and forming at a first end a depression configured to receive a portion of the sphere and forming at a second and opposing end a protrusion or a recess to engage another of the plurality of three-dimensionally printed limb elements;
• a second three-dimensionally printed joint element forming at a first end a recess to receive a portion of the sphere;
• and
• a third three-dimensionally printed modular limb element having an end configured to receive the outer extremity of the amputated limb instead of engaging an adjacent limb element.
