Abstract
A lower limb modular prosthetic system that may be fabricated by a 3D printer capable of printing with composite fiber filament, nylon, or metal. The production process may include a 3D printer that is capable of routing fiber in specifically programmed patterns. The components of the prosthetic system may be designed for direct patient end-use, and may be energy returning in nature.
Claims17
A prosthetic, comprising:
- a plurality of layers that are stacked in abutment with each other so that each layer is aligned in parallel along a common plane to build up a three-dimensional body, wherein the body comprises a foot having a heel and a forefoot interconnected to the heel by a curved portion;
- wherein each layer of the plurality of layers of the body comprises a series of boundary rings that are positioned concentrically and in abutment with each other so that an outside of each ring of the series of boundary rings is abutting the outside of another ring of the series of boundary rings to build each of the plurality of layers;
- and
- wherein each boundary ring of the series of concentric boundary rings is formed from a single continuous composite fiber.

A prosthetic system, comprising:
- a foot formed from a first plurality of layers stacked in abutment with each other so that each layer of the foot is aligned in parallel along a first common plane to build up a three-dimensional body, wherein each layer of the plurality of layers of the body comprises a first series of concentric boundary rings that are positioned concentrically and in abutment with each other so that an outside of each ring of the series of boundary rings abuts the outside of another ring of the series of boundary rings to build such layer and each boundary ring of the first series of boundary rings is formed from a single continuous composite fiber, wherein the foot has a first mounting portion;
- and
- a pylon formed from a second plurality of layers stacked adjacently to each other so that each layer of the body is aligned along a second common plane, wherein each layer of the second plurality of layers of the pylon comprises a second series of concentric boundary rings that are positioned concentrically and in abutment with each other so that an outside of each ring of the second series of boundary rings is adjacent to and abuts the outside of another ring of the second series of boundary rings to build each of the plurality of layers, wherein each of the second series of boundary rings is formed from a single continuous composite fiber, wherein the pylon is interconnected to the first mounting portion.
