Hackaday highlights a 3D printed wind turbine:
The WinDIY design is mostly 3D printed, with a familiar three-bladed design. The diameter of the rotor is 1.2 m, meaning that braking and regulating the turbine is required for safety in high winds. [Fab] is aiming to achieve this control with a combination of mechanical and electronic braking, as well as variable-pitch blades. The benefit of 3D printing the design is it allows iterations to be made quickly, particularly of parts with complex geometries that would be too time-consuming or expensive to machine otherwise.
[Fab]’s writeup goes into great detail on topics like the design of the pitch control systems and other minutae, which should serve as a great reference for anyone else working on a similar project. If you’re looking for something with more of a sci-fi future vibe, consider attempting a vertical-axis build instead.
