Abstract (en)
[origin: WO2019212551A1] The present disclosure is directed to a method for manufacturing a rotor blade component, such as shear web, of a rotor blade of a wind turbine. The method includes forming, via 3-D printing, an intemal lattice structure of the rotor blade component. More specifically, the internal lattice structure includes a plurality of open cells. In addition, the method includes covering at least a portion of the internal lattice structure with an outer skin layer to form the rotor blade component.
