Abstract: An auxetic (NPR) structure includes a plurality of vertical intersecting dimpled sheets, each dimpled sheet exhibiting a negative Poisson's ratio, each dimpled sheet intersects two adjacent dimpled sheets creating a rectangular tubular structure, and having a portion of each dimpled sheet projecting outward from its intersection with an adjacent dimpled sheet, the amplitude of each dimple on the plurality of dimpled sheets is such that no overhanging surface of the dimpled sheet exceeds an angle threshold for printability without support structures.

Abstract: An investment casting core (10) incorporates an alignment guide (24) extending through a body (12) of the core. The alignment guide (24) defines a coolant flow path (92) in a later-cast metal component (76) extending from a coolant outlet opening (90) in an impingement structure (88) to an impingement target area (86) of a cooling feature (84) formed on an impingement cooled surface (82) of the component (76). Methods of making the core (10) and using the core (10) in lost wax investment casting processes are also described.
