Problems solved by technology

[0003] In the traditional additive manufacturing process, the entire format uses the same size of light spot. When the light spot is too large, the processing efficiency is high, but the surface roughness is high and the surface quality is poor; the light spot is too small, the surface quality of the part is better, but the processing efficiency is low.

Abstract

Double-beam high-surface quality rapid additive manufacturing equipment comprises a first laser additive device. The first laser additive device comprises a first laser 201, a first collimating mirror202, a first dynamic focusing mirror 203 and a first galvanometer 204, wherein divergent light emitted by the first laser 201 is collimated into parallel light through the first collimating mirror 202, then the parallel light enters the first dynamic focusing mirror 203 to converge into large light spots, the large light spots are projected to a processing plane 401 through the galvanometer 204,and the light spots projected to the processing plane 401 are large light spots. By means of the double-beam high-surface quality rapid additive manufacturing equipment, the high-surface quality 3D printed products can be produced, the machining efficiency is improved, and the surface quality is also improved.

Description

technical field [0001] The invention relates to a double-beam high-surface-quality rapid additive manufacturing equipment, which belongs to the technical field of additive manufacturing and is suitable for powder-based additive manufacturing. Background technique [0002] Additive manufacturing technology is a process technology in which materials are added and fused according to the three-dimensional digital model of the required processed product. The main difference from the traditional processing method is that the processing is realized by superimposing materials layer by layer. Among them, the powder-spreading 3D printing technology is currently one of the more mature and main 3D printing forming technologies. When processing, a layer of material powder is evenly spread on the processing plane, and the thickness of the powder is often determined according to the processing technology. Afterwards, the control system controls the laser to output laser, and scans the pr...
