Radial Impeller

youmagine

Making radial impellers for turbines in any size by printing them in sections. The sections can be attached to a flat base plate. In the images above, a CD is used as the foundation for the impeller, and the gaps between the small segments are sealed using a soldering torch. It has been spun up to 20,000 RPM with no issues using a Dremel. To balance it, hot glue is applied carefully. When operating, protective eyewear is essential! The parametric 3D model is publicly available at https://goo.gl/QBuZ6H - slice it without the top or bottom sections. It's hoped that people will share their findings on housing design and identify the optimal aerodynamic parameters. This can be used to create dust collectors and wind turbines for energy collection... a lot of fun!
