Abstract

A three-dimensional object producing method for producing a three-dimensional object using a curable composition A and a curable composition B, and using a curable composition C is provided. The method includes discharging either or both of the curable compositions A and B by an inkjet method and curing either or both of them, to produce a base cured product, and discharging the curable composition C containing a coloring material by an inkjet method and curing the curable composition C, to produce a cured product C. A deposited region (D1) formed by deposition of the curable composition C discharged is smaller than a base deposited region (D2) formed by deposition of the curable compositions A and B discharged. An absolute value of a total light transmittance difference between a cured product A of the curable composition A and a cured product B of the curable composition B is 10% or greater.
