Abstract
Provided is a method for producing a three-dimensional manufactured product, the method including: a shaping step of performing a vat photopolymerization process using a liquid photocurable composition containing a radically-polymerizable monomer, an inorganic filler, a photopolymerization initiator, an activating light absorbent, and a polymerization inhibitor, to obtain a shaped product having a shape corresponding to the shape of a target article and containing an effective amount of the photopolymerization initiator in the interior thereof; and a post-polymerization step of irradiating the shaped product with activating light at an irradiation intensity of 10 to 10,000 mW/cm, and then heating the shaped product at a temperature of 50° C. or higher and lower than 110° C., to polymerize an unpolymerized component contained in the shaped product. Further, provided is a method for producing a dental restoration, including producing the dental restoration according to this method for producing a three-dimensional manufactured product.
