Abstract: A method of fabricating a functionally graded turbine engine component is disclosed and includes the step of depositing layers of powder onto a base and solidifying/fusing each layer with a first directed energy beam to define a component. The method further includes varying a process parameter between deposited layers to define different material properties within the component. The method also proposes surface enhancement approach that can be used after depositing each layer to locally customize the material properties. The method also proposes machining the different internal surfaces to achieve the proper surface finishing required.
