The invention discloses a built-in bidirectional switching 3D printing scraper. The built-in bidirectional switching 3D printing scraper comprises a movable sliding plate and a blade; a through groove is formed in the movable sliding plate, and a sinking flat plate extending in the direction of the printing platform is arranged on the groove wall of the through groove. The blade is embedded into the through groove and forms a material surrounding groove with the sinking flat plate in a surrounding mode. A material surrounding groove is defined by the sinking flat plate and the blade, so that a printing material is restrained in the material surrounding groove all the time and does not overflow, a fence does not need to be arranged outside a non-working area any more, and the overall structure is simplified. Printing materials are prevented from overflowing, the printing materials are saved, and unnecessary resource waste is reduced; and the printing material is always limited in a specific range, so that clea
