Title:
APPARATUS FOR MULTI-NOZZLE METAL ADDITIVE MANUFACTURING
Document Type and Number:
WIPO Patent Application WO/2019/055343
Kind Code:
A3
Abstract:
An assembly for rapid manufacturing of symmetrical objects by direct metal deposition is disclosed. A rotary stage provides rotational movement to an object supported by the stage around a central stage axis. Nozzles are spaced above the rotary stage for performing direct metal deposition for building an object supported by the stage. Each nozzle is independently moveable along a horizontal axis and independently pivotable, and combined, moveable along a vertical axis for providing symmetrical movement corresponding to a symmetrical deposition configuration of the object while the object is rotated around the central stage axis.
