Load-balanced knee joint orthopedic brace and implementation method thereof

The invention discloses a load-balanced knee joint orthopedic brace and a 3D printing method thereof. The printing method includes designing and printing of a thigh supporting part, a shank supporting part and a connecting part; both the thigh supporting part and the shank supporting part are represented as an annular curved surface; the connecting part comprises a leg inner side connecting unit and a leg outer side connecting unit; and the designing includes 3D scanning and modeling, manifold, relaxation, offsetting and shelling. The brace disclosed by the invention is simple in structure and reasonable in design, and is capable of preventing further abrasion of a knee joint under a flexion-extension state; and the printing method, which conducts 3D printing by virtue of polylactic acid fiber, has a good physical effect.
