Abstract

See full text

An array-spraying additive manufacturing apparatus and method for manufacturing a large-sized equiaxed crystal aluminum alloy ingot, comprising: a liquid aluminum spraying mechanism having array nozzles disposed in an atmospheric pressure chamber, a movable condensing mechanism disposed in the atmospheric pressure chamber below the liquid aluminum spraying mechanism, and a control mechanism. The control mechanism sends an upward guiding command to a release mechanism and issues a three-dimensional movement command to the movable condensing mechanism, such that liquid aluminum in the liquid aluminum spraying mechanism is sprayed at the surface of the movable condensing mechanism in a continuous array of liquid flows according to a preset path and is rapidly condensed to form an ingot. Also disclosed is an additive manufacturing method employing the apparatus.
