The invention relates to the technical field of additive manufacturing equipment, in particular to an additive manufacturing powder drying and screening integrated device and a using method.The additive manufacturing powder drying and screening integrated device comprises a drying and screening cabinet and screens, and the multiple screens are arranged in the drying and screening cabinet at equal intervals from top to bottom according to the sequence that the apertures are gradually decreased; a drying lamp is arranged between every two adjacent screens; each screen is correspondingly provided with a scraper unit, and a scraper in each scraper unit can reciprocate at a constant speed in the horizontal direction so as to turn over and push powder in the screen corresponding to the scraper unit. The scraper unit further comprises a ball screw driving the scraper to do reciprocating constant-speed motion in the horizontal direction, and the ball screw is driven by a motor. A vibration screening mode is abandoned
