Abstract

Equipment capable of improving the laser selection melting and forming efficiency comprises a forming unit, a powder supply unit, a powder recovery unit and a laser control unit; the forming unit is used for bearing a forming part (3), an unformed powder binding layer (5) and unformed powder; the powder recovery unit is used for spreading powder according to the section shape of the forming part (3) in a plane to be formed; meanwhile, the unformed powder binding layer (5) is formed; the powder recovery unit is used for bearing unformed powder; and the laser control unit is used for scanning powder in the plane to be formed according to a scanning path generated by the part section information of the forming part (3), so that the spread powder is melted into a part of the forming part (3).The invention further provides a using method of the equipment capable of improving the laser selection melting and forming efficiency.

Description

technical field [0001] The invention relates to a device capable of improving the efficiency of selective laser melting and forming and a method for using the same, belonging to the technical field of additive manufacturing. Background technique [0002] Compared with other additive manufacturing technologies, laser selective melting forming technology has the advantages of high precision and high performance, and has become an important force in the field of additive manufacturing to make up for the shortcomings of traditional processing methods. Although this technology has greatly reduced the forming cycle of the parts compared with the traditional processing technology, it is still an important task for the relevant staff to further improve the forming efficiency. To this end, people have successively developed methods and technologies that can improve the forming efficiency of laser selective melting forming technology, such as path optimization, variable speed scraper,...
