Abstract To provide a technique for detecting a coating failure of a powder material, and suppressing deterioration in dimensional accuracy of a molded article due to the coating failure.SOLUTION: A three-dimensional laminate molding apparatus includes: a powder coating apparatus 16 which has a squeegee, and coats a powder material to a molding plate 22 and forms a powder layer; a camera for imaging a molding surface of the powder layer; and a determination part for determining whether or not a coating failure of the powder material has occurred using the image imaged by the camera during or immediately after passage of the squeegee through the molding surface.SELECTED DRAWING: Figure 2 【課題】粉末材料の塗布不良を検出し、塗布不良によって造形物の寸法精度が低下することを抑制することができる技術を提供する。【解決手段】三次元積層造形装置は、スキージを有し、造形プレート22に粉末材料を塗布して粉末層を形成する粉末塗布装置16と、粉末層の造形面を撮影するカメラと、スキージが造形面を通過中または通過直後にカメラによって撮影された画像を用いて、粉末材料の塗布不良が発生したか否かを判断する判断部と、を備える。【選択図】図2
