Selective Laser Melting technology is one of the metal additive manufacturing technologies, and it has become an important choice for precision manufacturing of metal parts with high performance and complex shape. In the process of selective laser melting, the accuracy and efficiency of laying powders directly affect the quality and time of parts printing. In order to realize laying powder accurately and efficiently in printing process, the mechanical mechanism and movement strategy of the powder laying device are studied in this paper. A powder laying mechanism with automatic leveling function is designed. On the premise of ensuring the powder laying accuracy, a variable position powder laying movement strategy is proposed to improve the powder laying efficiency The case analysis results show that the laying powder efficiency has been increased by 49.2%.<\/jats:p>","DOI":"10.3233\/jcm-204672","type":"journal-article","created":{"date-parts":[[2020,10,2]],"date-time":"2020-10-02T13:55:44Z","timestamp":1601646944000},"page":"939-950","source":"Crossref","is-referenced-by-count":0,"title":["Design
