PROBLEM TO BE SOLVED: To provide an ink for 3D molding having a low viscosity, from which a 3D molded object having high levels of a yield stress, elongation and impact resistance can be manufactured, and a method for manufacturing a 3D molded object by using the above ink.SOLUTION: A model material ink for 3D molding by an inkjet process is provided, which comprises a photopolymerizable monomer, a polymer and a photopolymerization initiator. In the ink, the polymer has a molecular weight of 5000 or more and 30000 or less; a difference in a solubility parameter between the photopolymerizable monomer and the polymer is 0.5 to 2.0 (cal/cm); and a mass ratio of the polymer to the photopolymerizable monomer is 85/15 or more and 60/40 or less.SELECTED DRAWING: None |
