Double-beam high-surface quality rapid additive manufacturing equipment

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. 种双光束高表面质量的快速增材制造设备，包括第激光增材装置，第激光增材装置包括第激光器201、第准直镜202、第动态聚焦镜203和第振镜204，其中，第激光器201发出的发散光，经过第准直镜202准直为平行光后，进入第动态聚焦镜2
