PROBLEM TO BE SOLVED: To provide a model material applied to a three-dimensional molding method by an inkjet optical molding method extremely low in swelling due to water or moisture absorption, or moisture absorption deformation during optical curing and after curing.SOLUTION: A model material contains a monofunctional ethylenic unsaturated monomer (A) having weighted average of SP value of 10 or less, a polyfunctional ethylenic unsaturated monomer (B) containing no urethane group having weighted average of SP value of 10 or less and an urethane-containing ethylenic unsaturated monomer (C) having weighted average of SP value of 10.9 or less, further contains a photoinitiator (D) with the content of (B) of 3 to 25%, the content of (C) of 5 to 35%, the content of (D) of 0.1 to 10% based on weight of the model material and weighted average of SP values of the curable resin component (A) to (C) of the model material of 9.0 to 10.3.SELECTED DRAWING: Figure 1
