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.

Abstract: An assembly for measuring metal powder material mass flow rate during direct metal deposition is disclosed. A detection strip is placed in the gas-blown metal powder material flow path. The detection strip is fixed in one end and suspended at the other end. The flowing metal powder material particles induce displacement to the detection strip. A displacement measurement sensor measures the amount of displacement of the detection strip. The amount of displacement of the detection strip gives relationship to the amount of the metal powder material flowing in the metal powder material flow path. Preferably, the detection strip and the sensor are enclosed in a housing with a metal powder material inlet port and metal powder material outlet port and includes internal features for smooth travel of metal powder material particles.

Abstract: A source of heat energy and a source of material for performing a material additive process upon the thin wall member is disclosed. A fixture is located relative to the thin wall element. The source of heat energy used for forming a joining member between the workpiece and the fixture to fixedly secure the fixture to the workpiece preventing the thin wall member from deforming when subject to the source of heat energy. A direct material additive process is upon the thin wall member adding material to the thin wall member to improve physical characteristics of the thin wall member. The joining member is mechanically removed from the workpiece after the work piece cools. A portion of the material is mechanically removed from the thin wall member to achieve desired dimensional characteristics.

Abstract: A method of forming a three dimensional component includes predetermining a geometric configuration of the component. A first portion of the component is preformed from a first material by one of casting, forging, stamping, roll forming, extruding or molding. A second portion of the component is including a second material is deposited onto the first portion of the component using direct material deposition for reconfiguring the first portion to the predetermined geometric configuration of the component. The physical characteristics of the component are enhanced with the second portion providing a geometric configuration to the component not provided by preforming the first portion.
