摘要： A method for producing an artificial bone (1) is provided wherein electromagnetic waves or electron beams (7) are irradiated to a layer of one or more types of powder (2) selected from metal biomaterials, ceramics for an artificial bone (1) and plastic resins for an artificial bone (1) based on image data corresponding to a shape of the artificial bone, thereby effecting sintering or melting, and wherein the thus sintered layer or the thus melted and solidified layer is laminated, and wherein a surface finish step is adopted in which inner faces and/or outer faces of both ends (11) and their vicinities configuring a joined part to a human bone part are polished by a rotating tool (6) based on the image data, and wherein further the irradiation of electromagnetic waves or electron beams (7) at both ends (11) and their vicinities configuring the joined parts is increased as compared to other regions. Further, an artificial bone (1) is provided which is produced by the method.
