Example Embodiment

[0033] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0034] The metal three-dimensional additive manufacturing device of the present invention includes a jet nozzle 1, which is made of polypropylene and is provided with a conductor 5 made of platinum. The shape of the nozzle 15 is a rectangle with a width of 2 mm and a length of 10 mm, and the outlet is away from the cathode substrate. The height of 6 is 2mm; the film-forming nozzle 2 is provided with 2 nozzles communicating with the industrial paraffin in the hot melt state, the nozzle spacing is 10mm, the spacing can be adjusted in the range of 1-10mm, and the height between the outlet and the cathode substrate is 0.1mm; and The jet nozzle 3 with hot air communication and the cleaning nozzle 4 with an external deionized water source are also equipped with two nozzles. The nozzle spacing is always the same as the spacing of the film forming nozzle 2. The height ...

Abstract

The invention discloses metal three-dimensional additive manufacturing apparatus and method. The apparatus includes: a jet flow nozzle internally provided with an electric conductor, a film forming nozzle communicated with a high molecular polymer supply source, a gas ejection nozzle communicated with a hot gas source, a cleaning nozzle communicated with a deionized water source, a cathode substrate, an electro-deposition power supply, and an electrolyte cycle filter apparatus. In the apparatus, with scanning movement of the nozzles, the film forming nozzle stacks two rows of film layers on the cathode substrate, the gas ejection nozzle and the cleaning nozzle can rapidly clean and dry the surface of the films, and the jet flow nozzle ejects electrolyte to the zone between the two rows offilm layers on the cathode substrate, thus electro-depositing the metal layer in the localization manner; by increasing the height of the nozzles, the stack film layers and metal layers are added continuously, thus achieving the additive manufacturing of a three-dimensional metal member. The apparatus has simple structure and high efficiency, and can shape the three-dimensional metal member havinghigh compactness and precision.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to a metal additive manufacturing device and method. Background technique [0002] Compared with the commonly used processing modes such as subtractive material and equal material, additive manufacturing technology has been favored by the manufacturing industry in the past 10 years because of its advantages such as short manufacturing process, no restrictions on part shape, and few auxiliary operations. The metal additive manufacturing technology for the terminal manufacturing of metal parts is one of the focuses and hot spots in the industry and academia. More than 10 kinds of metal additive manufacturing methods such as Selective Laser Melting (SLM) and Laser Metal Direct Forming (LMDF) have been developed. Most of these metal additive manufacturing methods are based on the principle of thermal melting-solidification to realize the layer-by-layer superposition form...
