PROBLEM TO BE SOLVED: To stably fix a shaping object that is being shaped and, after shaping is completed, to separate the shaping object from a shaping surface in a short time without imposing a load on the shaping object.SOLUTION: Provided is a manufacturing method of a three-dimensional object by laminating a shaping material on a shaping stage by using additive manufacturing, which includes a step of forming an underlay part containing a water soluble carbohydrate on a shaping surface on the shaping stage; and a step of laminating the shaping material on the underlay coat in accordance with a sectional shape of the three-dimensional object.SELECTED DRAWING: Figure 3 【課題】 造形中の造形物を安定して固定すると共に、造形完了後には、造形物に負荷をかけることなく造形物と造形面とを短時間で分離する。【解決手段】 造形ステージの上に積層造形法を用いて造形材料を積層して立体物を製造する、立体物の製造方法であって、前記造形ステージの上の造形面に水溶性炭水化物を含む下地部を形成する工程と、前記下地部の上に、前記立体物の断面形状に応じて造形材料を積層する工程と、を有することを特徴とする。【選択図】 図３
