Claim:
1. A modeling material for forming a photofabrication model in ink-jet three dimensional printing method, comprising curable resin ingredients (A) to (C) with a weighted average of SP value of 9.0 to 10.3 and a photopolymerization initiator (D), wherein curable resin ingredient (A) is a monofunctional ethylenically unsaturated monomer (A), curable resin ingredient (B) is a polyfunctional ethylenically unsaturated monomer containing no urethane group (B), curable resin ingredient (C) is a urethane group-containing ethylenically unsaturated monomer (C) and, wherein the content of (A) is 50 to 90%, the content of (B) is 3 to 25%, the content of (C) is 5 to 35%, and the content of (D) is 0.1 to 10% on the basis of the weight of the modeling material, and the water-swelling ratio of a phototcured product of the modeling material is not more than 1% by weight.
