Abstract
A process of forming an air cooled turbine airfoil using a metal additive process, where the airfoil is formed by first producing a ceramic core having an internal cooling circuit shape, and then building up the airfoil over the ceramic core. The ceramic core is then leached away, and the outer surface of the airfoil is machined to remove rough surfaces formed by the metal additive process.
