    Abstract: A laser net shape manufactured BLISK, compressor blade, turbine blade or turbine component including a plurality of overlapping predetermined variable bead widths of a material defining a first material layer, a plurality of overlapping predetermined variable bead widths of a material deposited on top of the first material layer, forming a second material layer; and additional material layers deposited on top of the first material layer and the second material layer. The variable bead width of the deposited material is controlled to maintain the approximately constant percent of bead width overlap. A first 2 to 100 deposited powder layers are deposited by a first laser power and the remaining powder layers are deposited by a laser power that is ramped down over the course of depositing the remaining powder layers. In addition, disclosed is A BLISK, compressor blade, turbine blade or turbine component formed by a method.

    Abstract: A collimator grid and a method of fabricating the collimator grid are disclosed. The method includes molding a plurality of plates, each plate includes a plurality of grooves in a first surface, a plurality of fin tips in a second surface disposed opposite to the first surface, plurality of ribs on a first pair of peripheral sides, a plurality of first fiducials formed on the plurality of ribs, and a plurality of second fiducials formed on a second pair of peripheral sides. The method includes machining the second surface to form the plurality of fins having predefined dimensions. Further, the method includes stacking the plurality of plates overlapping each other based on the plurality of first fiducials, and machining the plurality of ribs and first fiducials to form the collimator grid.
