Abstract
A method for producing an artificial bone capable of accurate molding at a joined part with appropriate strength, in which electromagnetic waves or electron beams are irradiated to a layer of at least type of powder selected from metal biomaterials, ceramics for the artificial bone and plastic resins for the artificial bone based on image data corresponding to a shape of the artificial bone, thereby effecting sintering or melting, and the thus sintered layer or melted and solidified layer is laminated, such that a surface finish step is adopted that inner faces and/or outer faces of both ends and their vicinities configuring the joined part to a human bone part are polished by a rotating tool based on the image data and also irradiation of electromagnetic waves or electron beams at both ends and their vicinities constituting the joined part is set greater than that at other regions.
