The invention discloses an integrated forming additive manufacturing device and method of a multi-material component. The forming device comprises a powder feed system and a forming cylinder. The powder feed system comprises a powder flow powder feeder, powder feed pipelines and a multi-way powder mixing nozzle. The multiple powder feed pipelines are arranged, and the powder feed pipelines serve as pipelines used for allowing the powder flow powder feeder to convey powder to the multi-way powder mixing nozzle. The device further comprises a powder clearing system. The powder clearing system comprises a dust collector, a powder clearing pipeline and a powder clearing nozzle. The powder clearing pipeline serves as a connecting pipeline between the dust collector and the powder clearing nozzle, so that when the dust collector works, suction force for sucking powder on a powder feed cylinder and the forming cylinder is generated at the inlet end of the powder clearing nozzle. The forming device further comprises
