AI Technical Summary
Existing additive manufacturing technologies are prone to damaging the original structure of parts with concave features, and the processing quality and efficiency are not high.
A powder spreading and scraping device for laser selective melting of concave structures is designed, including a powder spreading mechanism and a scraper device. Through the coordinated design of synchronous rotation and scraper, local directional powder spreading and scraping of concave feature structures can be achieved, avoiding interference with other structures. It is suitable for local additive manufacturing of concave features.
Without damaging the original structure of the part, efficient local additive manufacturing of concave feature structures was achieved, improving processing quality and efficiency.
