Zusammenfassung:	To provide a lamination molding method capable of favorably removing residual powder remaining in a path formed inside a molded object.SOLUTION: A lamination molding method according to the present invention includes a step of acquiring design data of a molded object (step S10), a step of determining a removability of a powder remaining when a molded object is manufactured based on the design data, based on at least one or more factors of a particle size distribution, shape, size, or stacking position of the powder (step S20 ), a step of modifying the design data so that the removability of the determined powder is improved (step S30), and a step of manufacturing the molded object based on the modified design data (step S40).SELECTED DRAWING: Figure 3 【課題】造形物の内部に形成された経路に残留する残留粉末を良好に除去することが可能な積層造形方法を提供すること。【解決手段】本発明に係る積層造形方法は、造形物の設計データを取得する工程（ステップＳ１０）と、設計データに基づき造形物を製造した場合に残留する粉末の除去性を、粉末の粒度分布、形状、大きさ、または積層位置のうち少なくとも１つあるいは複数の因子に基づいて判定する工程（ステップＳ２０）と、判定された粉末の除去性が向上するように設計データを修正する工程（ステップＳ３０）と、修正された設計データに基づいて造形物を製造する工程（ステップＳ４０）と、を有する。【選択図】図３
