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.
