PROBLEM TO BE SOLVED: To provide a production method of a three-dimensional molded object which makes the strength of a three-dimensional molded object compatible with impact resistance and high definition.SOLUTION: A production method of a three-dimensional molded object is for production of a three-dimensional molded object including a heat-meltable resin part composed of one or more layers and an inkjet ink part composed of one or more layers and comprises a step of discharging a heat-meltable resin from a first discharge nozzle to form layers constituting the heat-meltable resin part on a stage and a step of discharging an active ray-curable ink for three-dimensional molding from a second discharge nozzle by an inkjet system and irradiating with active rays to form layers constituting the inkjet ink part on the stage. 【課題】三次元造形物の強度および耐衝撃性と高精細性とを両立させることのできる三次元造形物の製造方法を提供する。【解決手段】１または複数の層からなる熱溶融樹脂部と、１または複数の層からなるインクジェットインク部とを含む三次元造形物を製造する方法であって、熱溶融樹脂を第１の吐出ノズルから吐出して該熱溶融樹脂部を構成する層をステージ上に形成する工程と、活性光線硬化型の三次元造形用インクを第２の吐出ノズルからインクジェット方式で吐出し、活性光線を照射して、該インクジェットインク部を構成する層をステージ上に形成する工程と、を含む、方法。【選択図】図４
