摘要： A method for producing an impeller, includes the following steps: a forming step of forming the impeller by fused deposition modeling; and a polishing step of polishing a wall that defines a channel of the impeller using particulate polishing materials. The particulate polishing materials are sprayed on the wall of the channel or the wall of the channel is rubbed with the particulate polishing materials in the polishing step.
