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 【課題】金型を製作して成形した正規の部品が求められる性能を発揮可能とする樹脂成形品量産用の金型の製造方法、成形方法、樹脂型の製造方法及び樹脂型の提供。【解決手段】量産用の成形金型の製作に先立って、樹脂型の三次元ＣＡＤデータに基づき三次元印刷機器を用いて、光硬化後の荷重たわみ温度が４５℃以上である光硬化性樹脂を印刷して樹脂型を得て、その樹脂型を用いて量産用の成形材料である樹脂原材料を成形し、その成形物の調査を行い、その調査結果を量産用の成形金型の製作の際に反映させる樹脂成形品量産用の金型の製造方法。【選択図】図１
