The invention discloses a manufacturing method of a 3D printing railway fastener system polymer part follow-up runner mold. The manufacturing method comprises the following steps: 1) establishing a three-dimensional model of the 3D printing railway fastener system polymer part follow-up runner mold by using modeling software, and importing the three-dimensional model into a 3D printer; (2) a 3D printer is used for printing a primary finished product of the shape follow-up runner mold of the polymer component of the 3D printing railway fastener system according to the three-dimensional model imported in the step (1); and (3) post-processing the primary finished product of the shape follow-up runner mold of the high-molecular component of the railway fastener system printed in the step (2), and manufacturing to obtain a finished product of the shape follow-up runner mold of the high-molecular component of the railway fastener system. The railway fastener system polymer component shape follow-up runner mold manu
