Abstract:
1. A method for producing an artificial bone comprising the steps of: irradiating one of electromagnetic waves and electron beams to a layer of at least one type of powder selected from metal biomaterials, ceramics for an artificial bone and plastic resins for an artificial bone, based on image data corresponding to a shape of the artificial bone, thereby effecting at least one of sintering and melting, laminating the thus sintered layer or the thus melted and solidified layer, a surface finish step of polishing at least one of inner faces and outer faces of both ends and vicinities thereof configuring a joined part to a human bone part by a rotating tool based on the image data, and said step of irradiating irradiates said both ends and their vicinities which configure the joined part, by said one of electromagnetic waves and electron beams, with a radiation dose which is set greater than a radiation dose for other regions by one of: to prevent fatigue and friction of said joined part.
