PROBLEM TO BE SOLVED: To provide a 3D shaped object manufacturing method capable of manufacturing a high strength shaped object having the strength of a 3D shaped object, in particular excellent extension and hardness.SOLUTION: A 3D shaped object manufacturing method comprises: a step of forming a 3D shaped object precursor containing a model material; and a step of, after the step of forming the 3D shaped object precursor, postcuring the 3D shaped object precursor; and a step of removing a cured product of a support material. The model material contains a photopolymerizable compound and a photoinitiator. The photopolymerizable compound comprises a first monomer having at least one of a water-curable functional group and a thermosetting functional group and one ethylenically polymerizable group. Th postcuring is performed under a condition where the water-curable functional group or the thermosetting functional group of the first monomer is reacted. The glass transition temperature (Tg) of the precursor is 50°C or more. |
