Abstract

A device capable of improving the efficiency of laser selective melting forming, comprising a forming unit, a powder supply unit, a powder recovery unit, and a laser control unit; the forming unit is used to carry formed parts (3) and an unformed powder fastening layer (5) and unformed powder; the powder supply unit lays the powder according to the shape of the section of the in-plane forming part (3) to be formed; simultaneously forms the unformed powder fastening layer (5); the powder recovery unit is used to carry the unformed Formed powder: the laser control unit scans the powder in the surface to be formed according to the scanning path generated by the part cross-section information of the formed part (3), so that the laid powder is melted into a part of the formed part (3). The invention also includes a method for using the equipment that can improve the efficiency of laser selective melting and forming.

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,...
