Abstract: A aerodynamic particle separator for an Additive Manufacturing System (AMS) has an air supply device to entrain a mixed powder in an airstream flowing through a housing. Each particle in the mixed powder is imparted with a momentum dependent upon the particle weight and size. Utilizing this momentum characteristic, the heavier particles are capable of crossing streamlines of the airstream at a bend portion of the housing and the lighter particles generally stay within the streamlines. Utilizing this dynamic characteristic, the particles of specific weight ranges are collected through respective offtake holes in the housing and controllably fed to a spreader of the AMS.

Abstract: A method of forming a metal component with two and three dimensional internal functionally graded alloy composition gradients includes forming the component by a powder based layer-by-layer additive manufacturing process. The areal composition distribution of each powder layer is determined by simultaneously depositing different powders and powder mixtures through a mixing valve attached to a single nozzle during powder deposition. The layers are then sintered with a directed energy source to form a forging preform. The preform is then forged to form a component.

Abstract: A method of forming a component includes preparing a starting powder and spreading the powder on a platform to form a first layer. A first mask with a plurality of openings is placed over the platform and the platform is irradiated with an energy source, such that the energy passes through the openings in the mask and transforms selected regions of the first layer into a denser form of matter according to a 3-D model of the component stored in a control system of the device. The platform is then indexed down one layer of thickness and a second layer of powder is spread on the first layer. A second mask with a plurality of openings is positioned between the energy source and the first layer and the first layer is irradiated with energy that passes through the mask and transforms selected regions of the second layer into a denser form of matter. The platform is indexed down one layer of thickness again and the process repeated until the component is formed.
