Additive and subtractive manufacturing (e.g. 3D Printing) is used to form aeroelastic airfoils with control surface region(s) having conventional rib/spar structural topologies and a continuous skin (e.g smooth surface) formed over the entire outer surface of the airfoil. The control surface is moved with internal actuators resulting in a “morphing” airfoil as the skin stretches to follow the moving structure of the control surface region. The airfoil can include a plurality of different material moduli and geometric featuring to balance the appropriate control of stiffness with topological requirements.
