Laser and microbeam plasma composite 3D (3-dimensional) printing equipment and method

Abstract

The invention discloses a laser and microbeam plasma composite 3D (3-dimensional) printing equipment and method. The equipment comprises a central control system, a sealing forming chamber, a laser forming device and a plasma processing device, wherein a laser forming spray head and a plasma gun are correspondingly put on a support frame arranged at the left and right side inner walls of the sealing forming chamber, and the laser forming spray head or the plasma gun is clamped through a co-work numerical control main shaft, so that the laser forming spray head or the plasma gun moves in the Z, X and Y directions in the sealing forming chamber. The central control system controls the co-work numerical control main shaft for conveying back the laser forming spray head back to the support frame, then, the co-work numerical control main shaft clamps the plasma gun for filling the inside of the profile of a formed metal part, and the work is alternately carried out in such a way until the part manufacturing is completed, so that the scanning time is reduced to a great degree. The laser fast forming is combined with the plasma, the problem of conflict between the efficiency and the precision of a metal 3D printing technology is solved, and in addition, the plasma is adopted for replacing the laser to be used as a heat source, so that the high-efficiency and low-cost industrial level metal 3D printing equipment is obtained.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing of metal parts, in particular to a laser and micro-beam plasma composite 3D printing device and method. Background technique [0002] Laser 3D printing equipment integrates laser, precision transmission, new materials, CAD / CAM and other technologies. Through the fine laser focusing spot of 30-80 microns, the selected area on the new powder layer is overlapped and scanned line by line, and the surface contour is formed. Layer-to-layer stacking and forming, so as to directly obtain metal functional parts with almost any shape and complete metallurgical bonding, and the density can reach nearly 100%. Its advantages are mainly manifested in: [0003] 1) Using layered manufacturing technology, the formed parts are not affected by the geometric complexity, and any complex formed metal parts can be directly manufactured, which is convenient for the manufacture of personalized small batch c...

Problems solved by technology

Due to the high price of lasers and troublesome maintenance operations, it is not conducive to the industrial application of laser 3D printing equipment

Although the latter can realize the direct manufacture of large parts by using certain control methods, but in order to ensure the precision and surface roughness of the parts, the molding efficiency must be sacrificed.
