PROBLEM TO BE SOLVED: To provide a method for manufacturing a three-dimensional molded article, by which a three-dimensional molded article can be efficiently manufactured, and a high-quality three-dimensional molded article.SOLUTION: In the method for manufacturing a three-dimensional molded article, layers are stacked to manufacture a three-dimensional molded article. The method includes: a layer formation step of forming a layer by using a composition for three-dimensional molding, which comprises particles, a binder resin, and a solvent; an ejection step of ejecting a binding solution comprising a binder to the layer; and after repeating the layer formation step and the ejection step, a removal step of removing the particles not bound by the binder by using a removal solution. The binder resin has a water-soluble functional group having a pKa to water smaller than a pH of the removal solution. |
