Abstract
A wind turbine blade includes a lengthwise portion that extends between a root region and a tip region of the wind turbine blade. The lengthwise portion includes a cross section in which a first region surrounds a second region. The densities of the first and second regions vary with the first density being greater than the second density. The lengthwise portion includes a surface layer that bounds the first region, forms an exterior surface, and is configured to resist environmental degradation. At least one structural element extends longitudinally through the first region and is configured to reinforce the blade during use of the wind turbine. The lengthwise portion of a wind turbine blade may be made through an additive manufacturing process by depositing a main body in a plurality of layers. Each layer may be deposited in a plane generally parallel to a longitudinal axis of the lengthwise portion.
