[Problem] The present invention addresses the problem of providing: a supporting material for shape support, which is able to be efficiently removed after shaping in additive manufacturing; and an active energy ray-curable resin composition which is used for the purpose of forming the supporting material. [Solution] By using an active energy ray-curable resin composition which contains (A) an ionic monomer, (B) a non-ionic water-soluble monomer, (C) a non-polymerizable compound, (D) a photopolymerization initiator, and/or (E) a polyfunctional monomer, a supporting material is able to be efficiently removed from a roughly shaped object, whereby a three-dimensional model with high modeling accuracy is able to be obtained without undergoing surface contamination. |
