To realize molding with high precision without lowering of molding efficiency even if a recess surrounded with a hardened part is formed during molding.SOLUTION: A three-dimensional molding apparatus includes a molding bath that houses a resin composition and a recoater that smooths a liquid surface of the resin composition by moving in a predetermined direction. The recoater includes a first part that smooths the resin composition in front and a second part that smooths the resin composition in back when moving in the predetermined direction, and a bottom end of the first part is higher than a bottom end of the second part in a vertical direction.SELECTED DRAWING: Figure 1 【課題】 造形中に硬化部で囲まれた凹部が形成されても、造形効率を低下させることなく、精度の高い造形を実現する。【解決手段】 樹脂組成物を収容する造形槽と、所定の方向に移動して前記樹脂組成物の液面を均すリコータを備える三次元造形装置であって、前記リコータは、前記所定の方向に移動させたときに、前方で前記樹脂組成物を均す第１の部分と、後方で前記樹脂組成物を均す第２の部分と、を備え、鉛直方向において、前記第１の部分の下端が前記第２の部分の下端よりも高いことを特徴とする。【選択図】 図１
