description An object of the present invention is to provide a method for manufacturing a three-dimensional molded product capable of performing support at high accuracy using a support material having sufficient hardness and rigidity, capable of removing the support material efficiently after molding, and requiring no finishing step in manufacturing a three-dimensional molded product by an inkjet optical molding method, and a three-dimensional molded product manufactured by this method. A roughly molded product formed from a model material (A) forming a molded product and a support material (B) supporting the shape of the model material (A) during molding is immersed in a washing liquid (C). At this time, the support material (B) swells at a swelling ratio of 10% or more, and is thereby peeled from an interface with the model material (A) having a swelling ratio of 1% or less. Then, the support material is easily and completely removed without applying an external force. Furthermore, a three-dimensional molded product can be manufactured with high accuracy and high efficiency.
