摘要： Methods and systems for additively casting of a metallic object include constructing a mold region of a current production layer before producing the object region of the current production layer; depositing molten metal at a predetermined temperature in working areas at the object region of the current production layer according to a building plan; and moving one or more heaters over the deposition path and heating the working areas. The heating includes (1) heating the working areas to a pre-deposition target temperature before depositing metal on the working areas to affect a bonding of the molten metal with the working areas, and/or (2) heating the working areas to a post-deposition target temperature after depositing metal on the working areas to affect a thermal cooling profile of the working areas, the heating also includes providing annealing heating to earlier production layers by heat conduction through the current production layer.

摘要： A casting system for casting an object, wherein the casting system may include a mold system, a replaceable material provision system, and a molten metal processing system. The casting system may be configured to additively produce multiple production layers, one currently-produced production layer after the other. For each currently- produced production layer: (i) the mold system is configured to form one or more mold-layers, (ii) the replaceable material provision system is configured to provide one or more replaceable material layers; and (iii) the molten metal processing system is configured to form one or more current object regions of the currently-produced production layer by providing molten metal that replace the one or more replaceable material layers.

摘要： System and method for additive casting of metal objects by constructing production layers having mold regions and object regions includes a mold construction unit to construct a mold region of the current production layer; a Preparation-Deposition-Post (PDP) unit including: a molten metal depositor to deposit molten metal in an object region; a holder for holding the molten metal depositor; at least one induction heating unit; a build table for supporting the vertical stack of production layers; a movable platform to provide relative movement between the PDP unit and the build table; and a controller for controlling the PDP unit and the movable platform to deposit molten metal in a fabrication area, and to control the PDP unit to perform (1) pre-heating the fabrication area before molten metal deposition, to a pre-deposition temperature, and/or (2) post-heating the fabrication area after molten metal deposition, to a post-deposition temperature.
