The utility model relates to the technical field of additive manufacturing equipment, in particular to an additive manufacturing cladding head smoke dust fast exhaust device which comprises a flow guide cover, an air inlet unit and an air exhaust unit, the flow guide cover comprises an air storage cavity and a top plate, the air exhaust unit is connected with the top plate, the air storage cavity is arranged on the outer side of the top plate in a sleeved mode, and a narrow-slit flow channel is arranged on the air storage cavity. The narrow-slit flow channel is opposite to the exhaust unit, and the air inlet unit is arranged on the outer side of the air storage cavity and communicates with the air storage cavity. The air inlet unit is connected with the air storage cavity, the narrow-slit flow channel is formed in the air storage cavity, the flow speed of airflow flowing out of the narrow-slit flow channel is increased, the pressure intensity of the inner side of the flow guide cover is reduced, and therefore
