Abstract

The invention discloses a micro beam plasma 3D (three dimensional) printing device and a micro beam plasma 3D printing method. The micro beam plasma 3D printing device comprises a plasma processing device, a central control system, a shaping chamber, a work platform, a numerical control main shaft, a drive device and a powder feeding device. The plasma processing device comprises a plasma power source, a plasma generator, a plasma arc pressure increasing device, a plasma gun, a work gas circuit and a cooling water circuit. The plasma generator, the plasma arc pressure increasing device, the plasma gun, the work gas circuit and the cooling water circuit form a plasma processing integration unit. When the micro beam plasma 3D printing device is used in processing, the numerical control main shaft clamps the plasma processing integration unit, and is driven by the drive device to move in the XYZ direction, and the work platform moves up and down, and achieves feeding in the X direction. According to the micro beam plasma 3D printing device and the micro beam plasma 3D printing method, micro beam plasma is used as a hot source of melting metal material in metal 3D printing, and the industrial grade metal part 3D printing device high in efficiency and low in cost can be obtained on the premise that shaping accuracy similar to that in a laser 3D printing technology is guaranteed.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing of metal parts, in particular to a micro-beam plasma 3D printing device and method. Background technique [0002] 3D printing equipment integrates optics, precision transmission, new materials, CAD / CAM and other technologies. Through the fine high-energy density focusing spot of tens of microns, the selected area on the new powder layer is scanned line by line. After forming the surface outline, the layer It is manufactured with layer accumulation molding, so that metal functional parts with almost any shape and complete metallurgical bonding can be directly obtained, 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 smal...
