Fiber-reinforced 3D printed polymer pelvis substitute

A fiber-reinforced 3D printed polymer pelvis substituteis divided into an acetabulum-free pelvis substitute and an acetabulum-containing pelvis substitute, wherein the acetabulum-free pelvis substitute comprises a reinforced bearing part, a boundary part and a non-bearing part, and the acetabulum-containing pelvis substitute comprises a reinforced bearing part, a boundary part, a non-bearing partand an acetabular cup part; the boundary part is connected with the bone; the non-bearing part plays a role in maintaining the original anatomical morphology of the pelvis; reinforced fibers are arranged in the reinforced bearing part and play a role in enhancing tensile strength and bending strength of the substitute. The trend of the reinforced fibers is determined according to the force line direction of the defect substitute part in the pelvis integral force line, and the fineness and the volume of the reinforced fibers are determined according to the stress distribution of the pelvis in aservice state, so that th
