A 3D-Printer offers unique manufacturing capabilities. Complicated parts can be manufactured without having to design and manufacture complicated tools. The following proposal seeks to use exactly this capability in order to manufacture a simple and small wind mill. The mill can power small generators (such as the Shimano DH-3N20) or pumps in remote locations or third world countries. Designing, manufacturing and testing this machine will definitely inspire a lot of kids to maybe become engineers. Using 3D printing offers unique flexibility.
The blades and their shape definitely belong to the more complicated parts. They are designed using the open source propeller design software supplied by Dr. Martin Hepperle (http://www.mh-aerotools.de/airfoils/javaprop.htm). All parts are printable within the available machining space. The design is by no means completed (time… ;)), but should show the principle.
In the above images, printed parts are colored red, standard part yellow.
