PROBLEM TO BE SOLVED: To provide a method for manufacturing a mold for mass production of a resin molded article for achieving such a purpose that a normal component molded by using a mold manufactured by the method can exhibit desired performances, and a molding method, a method for manufacturing a resin mold, and a resin mold.SOLUTION: The method for manufacturing a mold for mass production of a resin molded article includes the following steps: prior to manufacturing a mold for mass production, a resin mold is obtained by printing a photocurable resin, which shows a load deflection temperature of 45°C or higher after photo-cured, by using a three-dimensional printing apparatus based on a three-dimensional CAD data of the resin mold; a resin raw material as a molding material for the mass production is molded by using the obtained resin mold; a molded object thus obtained is inspected; and the inspection results are reflected in manufacturing the mold for the mass production.SELECTED DRAWING: Figure 1 |
