Abstract

A photocurable material formulation for a lost model that has a high elastic modulus, shows small thermal expansion, has heat resistance in a certain temperature region, and is free of a photoacid generator to be used in an epoxy material or the like. The formulation is a photocurable composition including curable materials formed of monofunctional (meth)acrylates each having a molecular weight of 150 or more and less than 350, and a bifunctional (meth)acrylate having a molecular weight of 200 or more and less than 400.
