Abstract: A rotor blade formed via additive manufacturing is provided. The rotor blade includes an airfoil and a coupled component. The airfoil includes a plurality of fused layers of a first material formed via additive manufacturing and defines a leading edge and a tip at a distal end. The coupled component includes a plurality of fused layers of a second material formed via additive manufacturing. An interlocking transition zone includes a plurality of projections alternately extending from the airfoil and the coupled component, respectively, to undetachably couple the airfoil and the coupled component.
