Processing system and method for production and reloading of photosensitive resin 3D printing supplies

The invention discloses a processing system and method for material replacement in production of photosensitive resin 3D printing supplies. The processing method comprises the following steps that S1, whether the capacity of raw materials in the material changing cylinder exceeds a preset value or not is determined; s2, when the capacity of the raw materials is lower than a preset value, a main frame is arranged on the side wall of a material changing cylinder; s3, a cleaning assembly is hung at the position of the main machine, and the cleaning assembly contains cleaning liquid; and S4, an execution command is input into the main machine, the main machine does horizontal circumferential movement in the direction of the upper end of the side wall of the material changing cylinder, the main machine drives the cleaning assembly, the cleaning assembly reciprocates up and down along the inner side wall of the material changing cylinder, and the cleaning assembly wipes the photosensitive resin 3D printing consumab
