PROBLEM TO BE SOLVED: To provide a three-dimensional molded article with excellent dimensional accuracy.SOLUTION: The three-dimensional molded article manufacturing method is a method for manufacturing a three-dimensional molded article through repeatedly forming layers by using a substantial-part forming composition and a support-part forming composition. The manufacturing method includes: a first pattern forming step which forms a first pattern by discharging the support-part forming composition; and a second pattern forming step which forms a second pattern by discharging the substantial-part forming composition. In the first pattern forming step, the support-part forming composition is discharged along a first scanning direction to form a first linear part. In the second pattern forming step, the substantial-part forming composition is discharged along a second scanning direction that intersects with the first scanning direction to form a second linear part, and edges of the second linear part are brought to be in contact with side faces of the first linear part.SELECTED DRAWING: None 【課題】寸法精度に優れた三次元造形物を提供すること。【解決手段】本発明の三次元造形物の製造方法は、実体部形成用組成物およびサポート部形成用組成物を用いて層の形成を繰り返し行うことにより、三次元造形物を製造する方法であって、前記サポート部形成用組成物を吐出して第１のパターンを形成する第１のパターン形成工程と、前記実体部形成用組成物を吐出して第２のパターンを形成する第２のパターン形成工程とを有し、前記第１のパターン形成工程では、第１の走査方向に沿って、前記サポート部形成用組成物を吐出して第１の線状部分を形成し、前記第２のパターン形成工程は、前記第１の走査方向と交差する第２の走査方向に沿って、前記実体部形成用組成物を吐出して第２の線状部分を形成し、当該第２の線状部分の端部を前記第１の線状部分の側面部に接触させることにより行う。【選択図】なし
