To provide a configuration that allows the tater of moldings applied to a powder bed fusion bonding device to be compensated for the aircraft characteristics and depth shrinkage of the device.SOLUTION: A method of creating data for a powder bed fusion bonding apparatus according to one embodiment includes the processes of acquiring basic data of a molding object to be fabricated by the powder bed fusion bonding apparatus 1, and correcting the basic data of the molding object based on dimensional information of raw data including dimensional information of a test part fabricated by a powder bed fusion bonding apparatus or a similar machine of the powder bed fusion bonding apparatus in the depth direction and dimensional information of basic data for fabricating the test part. The process includes the process of correcting the acquired basic data of the molding object based on the dimensional information of the basic data for fabrication.SELECTED DRAWING: Figure 33 【課題】粉末床溶融結合装置に適用される造形物のテータを、その装置の機体特性及び深さ方向の収縮を考慮して補正することを可能にする構成を提供する。【解決手段】一実施形態に係る粉末床溶融結合装置用のデータ作成方法は、粉末床溶融結合装置１で作製する造形物の基本データを取得する工程と、粉末床溶融結合装置又は粉末床溶融結合装置の同種機体で作製したテストパーツの深さ方向の寸法情報を含む生データの寸法情報と、そのテストパーツ作製用の基本データの寸法情報とに基づいて、取得した前記造形物の前記基本データを補正する工程とを含む。【選択図】図３３
