Brief overview of what this is about:
- Wind turbine build from 3D printed parts
- HAWT design
- Rotor diameters from 0.5 to 1.2m possible
- 3D printed wings
- Uses a 3D printed disk generator for energy generation
- Safety functions through active pitch adjustment of the wings, mechanical brake and electronic brake function via the disk generator
- Can be printed using any "normal" (20x20cm bed size) FDM Printer

1. Why (in general):
I actually started this project as a follow-up project from the Nerdiskerator (infos here: https://hackaday.io/project/172445-nerdiskerator-a-3d-printed-disk-generator). This is a disk generator that I initially built as a kind of experiment. When I had successfully built it up I thought "Just putting it on the shelf is a shame". (I like to build things that have a practical use even after they have been set up.) So the Nerdiskerator should also get a practical use and maybe even relieve my electricity bill a bit. :)
Since I have no flowing water in the area, a water turbine is unfortunately not an option to drive the generator. Fortunately there is wind here where I live. Not much, but certainly enough to be able to harvest some free watts from Mother Earth here and there.
When researching for available and easy replicable wind turbine designs, I noticed that there is a lot of scattered information about building a wind generator yourself. Unfortunately, many of them were old and none of them seemed to me to be easy to replicate. I was hoping somehow that someone out there had already developed a design for a wind turbine that could easily be "reprinted" with a 3D printer.
I found a couple of designs, but either they weren't suitable or consisted of parts that could only be printed with very large 3D printers. Unfortunately, there was not a 3D printable design for a HAWT wind turbine as I imagined. I was looking for something easy scalable, easy adaptable and of course it should be safe.
Since I couldn't find something like this I decided to develop an own design of an easy replicable HAWT wind turbine. :)
2. Why a HAWT-Design:
First, because of the many technical arguments:
HAWT wind turbines are more efficient because all blades work in the wind at the same time. In addition, none of the wings prevent the effect of the wind like it happens with a VAWT-design wind turbine.
Second, as a personal challenge:
I like the various technical problems that have to be solved here. Additionally, at least until now there are not many DIY HAWT designs for wind turbines available.
3. Why build yourself when you could simply buy it?
Of course you could also buy such a wind turbine....Read more »
