Hackaday Prize 2023: A 3D Printed Vertical Wind Turbine

September 23, 2023 by 23 Comments

We feature a lot of off-grid power projects here at Hackaday, whether they’re a micropower harvester or something to power a whole house. Somewhere in the middle lies [esposcar90]’s 3D-printed vertical wind turbine, which it is claimed can deliver 100 watts from its diminutive tabletop package.

It’s designed to be part of a package with another turbine but makes a very acceptable stand-alone generator. The arms have large scoop-like 3D-printed vanes and drive a vertical shaft up the centre of the machine. This drives a set of satellite gears connected to a pair of DC permanent magnet motors, which do the work of generating. For different wind situations, there are even some differing STL gear choices to speed up the motors. The motors are 12V devices, so we’re guessing the output voltage will be in that ballpark. However, it’s not made entirely clear in the write-up.

3D Printed Wind Turbine Uses Bamboo

April 21, 2015 by 16 Comments

Using wood and aluminum for wind turbines is one thing, but how about 3D printing the blades and using bamboo to hold them together?

[Jeff Heidbrier] of Hero Electronics decided to try something new. He designed his own wind turbine to use cheap and readily available bamboo, with 3D printed parts. It’s a vertical axis wind turbine, unlike the typical wind mills you see generating power. The blades were printed on a Thing-O-Matic (nice to see they still exist in the wild!), and the turbine blades are about a foot long.

To make sure everything was level, he used a laser level to ensure his bearing system worked well. All in all, it looks pretty sturdy, but who knows how it will hold up to mother nature. Unfortunately there’s no clip of it actually being used outside, but I guess that just means we’ll have to wait for part 2.
