Abstract
This invention relates to a method and a wind turbine blade, wherein one or more airflow modifying devices are attached to a wind turbine blade having a base aerodynamic profile. The base aerodynamic profile is configured to substantially carry the structural loading of this modified wind turbine blade. The airflow modifying device is manufactured via 3D-printing and/or via 3D-machining and optionally coated or laminated before attachment. Once attached, the airflow modifying device may further be coated or laminated before working the outer surfaces into their finished shape.
