Abstract: A manufacturing method is for repairing a damaged three-dimensional (3D) article having a fracture zone which is a site of a broken-off portion of the 3D article. The method includes using a forming tool to form an attachment feature into material at the fracture zone, imaging the 3D article including the fracture zone to provide image data, defining a repair portion 3D body based upon a comparison between the image data and data defining an intact 3D body, printing the repair portion 3D body including a complementary attachment features, and attaching the repair portion to the damaged 3D article through the interengagement of the complementary attachment feature and the attachment feature.
