    • 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.
    • 提供一种制造人造骨(1)的方法,其中电磁波或电子束(7)照射到选自金属生物材料,人造骨(1)的陶瓷和一种或多种人造骨的陶瓷中的一种或多种类型的粉末(2) 基于与人造骨的形状对应的图像数据,进行烧结或熔融的人造骨用塑料树脂(1),其中层压如此烧结的层或如此熔化和固化的层,并且其中表面精加工步骤 采用其中基于图像数据通过旋转工具(6)对构成与人骨部分的接合部分的两端(11)及其附近的内表面和/或外表面进行抛光,并且其中进一步照射 与其他区域相比,构成接合部分的两端(11)的电磁波或电子束(7)及其附近增加。 此外,通过该方法制造人造骨(1)。
