HAWT Wind Turbine Is Mostly 3D Printed:
Wind turbines are a great source of renewable energy, and a great DIY project, too. They can be built with all kinds of materials and the barrier for entry is low for the beginner. [Fab] has built just such a device, taking advantage of modern construction techniques, and dubbed it the WinDIY.
[...] [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.

Much cooler is the way my father made prop blades for the homebuilt airplane he made in high school...c.1930. He started with a drawing that showed the cross section and pitch for each section along the length, perhaps 10 stations over a 6 foot long prop--note, prop blades twist along the blade length. Then glued up several planks of good clear pine for a blank. Cut in the pitch at each station with back saw (using templates made from the drawing.) Then started working with a draw shave (draw knife) to develop the final shape. He reported that he could shape one blade in a morning and the other in the afternoon (2-blade prop). So a three blade (more complex around the hub) might have taken a couple of days.
I still have a sample of his work, very smooth and well proportioned.
How long will it take for a little 3D printer to make all the parts of this plastic wind mill?

The endorsement by Paris Hilton just writes itself.
