    Abstract: A method of casting a truss structure having spaced face sheets connected by columnar structures, including forming a three-dimensional pattern (3D pattern) in the shape of the truss structure with the spaced face sheets and columnar structures, forming a mold core of the 3D pattern by surrounding the pattern with a liquid and letting the liquid harden about the 3D pattern, removing the 3D pattern from the mold core, filling the mold core with a liquid alloy to cast and directionally solidify the truss structure.

    Abstract: A method for producing a layered object is provided. The method includes a) irradiating a given surface layer of the object with an energy beam to create an interaction zone on the surface layer; b) providing relative motion between the energy beam and the given surface layer so as to control the interaction between the energy beam and the given surface layer; c) introducing feedstock into the interaction zone so that the feedstock melts and forms a hot solidified surface after leaving the interaction zone; d) applying mechanical energy to the hot solidified surface; and e) repeating steps (a) through (d) to form at least part of the layered object.

    Abstract: Methods of manufacturing or repairing a turbine blade or vane are described. The airfoil portions of these turbine components are typically manufactured by casting in a ceramic mold, and a surface made up of the cast airfoil and at the least the ceramic core serves as a build surface for a subsequent process of additively manufacturing the tip portions. The build surface is created by removing a top portion of the airfoil and the core, or by placing an ultra-thin shim on top of the airfoil and the core. The overhang projected by the shim is subsequently removed. These methods are not limited to turbine engine applications, but can be applied to any metallic object that can benefit from casting and additive manufacturing processes. The present disclosure also relates to finished and intermediate products prepared by these methods.
