Zusammenfassung:	To provide an additive manufacturing method with an excellent modeling quality.SOLUTION: There is provided an additive manufacturing method for forming a modeled object by repeatedly performing a powder layer forming step of forming a powder layer containing powder for three-dimensional modeling and an application step of applying a modeling liquid to the powder layer. A base layer forming step of forming a base layer is provided before the powder layer forming step, and a powder filling rate of the base layer is higher than a powder filling rate of the powder layer.SELECTED DRAWING: None 【課題】造形品質に優れる積層造形方法の提供。【解決手段】立体造形用粉末を含む粉体層を形成する粉体層形成工程と、前記粉体層に造形液を付与する付与工程と、を繰り返すことで造形物を形成する積層造形方法であって、前記粉体層形成工程の前に、下地層を形成する下地層形成工程を有し、前記下地層の粉体充填率が、前記粉体層の粉体充填率よりも高いことを特徴とする積層造形方法である。【選択図】なし
