1. A method for manufacturing an orthopaedic prosthetic, the method comprising:
providing a manufactured acetabular shell component having an outer wall, wherein the outer wall comprises a distal rim and an outer surface that extends from the distal rim;
receiving a specified inclination angle or a specified version angle for the manufactured acetabular shell component;
determining a target orientation of the manufactured acetabular shell component relative to a patient's bone as a function of the specified inclination angle or the specified version angle, the target orientation defining an inclination angle corresponding to the specified inclination angle or a version angle corresponding to the specified version angle;
determining a position of an augment on the outer wall of the manufactured acetabular shell component, the position corresponding to a positive contour of the patient's bone when the manufactured acetabular shell component is positioned in the target orientation; and
additively manufacturing the augment coupled to the outer wall of the manufactured acetabular shell component at the position on the outer wall, wherein the augment extends outwardly from the outer surface at a position adjacent to the distal rim, wherein the augment comprises an outer surface that defines a customized patient-specific negative contour shaped to conform to the positive contour of a patient's bone, and wherein the positive contour comprises an acetabular rim of the patient's bone.
