Abstract

The invention relates to the field of 3D printing, and specifically relates to a 3D printing system and method. The 3D printing system is characterized in that a processor is used for generating a material increasing route and a material decreasing route; a powder paving assembly is used for paving powder into layered pieces in a plurality of times through a powder cylinder; after paving powder into the layered pieces each time, a dynamic focusing unit is operated to sequentially adjust the laser transmitted to a galvanometer by a laser into a large spot and a small spot; the large spot is used for preheating the layered pieces, and the small spot is used for processing the layered pieces based on the material increasing route; in addition, a milling assembly is used for processing the layered pieces based on the material decreasing route; before 3D printing, the large-spot laser is used for heating the layered pieces, so that the layered pieces are prevented from warping and deformingcaused by thermal stress.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to a 3D printing system and method. Background technique [0002] With the rapid development of science and technology, the research on 3D printing technology has gradually deepened, and various 3D printing systems have gradually appeared in our work and life. When 3D printing is carried out, it is often realized through the cooperation of the subtractive system. The additive and subtractive composite processing system is a composite system that integrates additive manufacturing and subtractive processing, so that the advantages of the two systems complement each other. [0003] At present, 3D printing is commonly used in powder-spreading laser printing. Although this method can form parts with arbitrary complex structures, some defects are prone to occur during the printing process. Unsatisfactory results, or even printing failure due to warping and deformation; or problems such as pore...
