Title: Article and method of forming an article

Abstract

A cooling article and method of forming a cooling article are provided. The cooling article includes a body portion separating an inner region and an outer region, an aperture in the body portion, the aperture fluidly connecting the inner region and the outer region, and a reinforcing feature extending at least partially along the body portion, the reinforcing feature being oriented with respect to a build direction. The method includes forming a body portion defining an inner region and an outer region, forming at least one reinforcing feature concurrently with the forming of the body portion, the at least one reinforcing feature extending at least partially along the body portion, and forming an aperture in the body portion, the aperture fluidly connecting the inner region to the outer region. The forming the body portion, forming the aperture, and forming the at least one reinforcing feature comprises additive manufacturing.
