▼This page was part of an MTU course MSE4777 OA and MSE4777 OB/MSE5777/EE4777/EE5777: Open-source 3-D printing

Please leave comments using the talk page. The course runs in the Fall semester. It is not open edit.

This is a cross-flow turbine,^[1] basically a water wheel turned by stream to produce energy. This provides energy without the cost of fossil fuels; while the only time and energy used to work on it is occasional maintenance and set up. This would used in developing areas around the world because it is much cheaper and less time consuming to make. The material cost of this turbine itself is significantly reduced using 3D-printing.

Bill of Materials

1. PLA or ABS Filament (1.75mm)
2. All of the STL files and the SCAD files are here.
3. Hexagon axle shaft

Tools needed

1. MOST Delta RepRap or similar RepRap 3-D printer
2. Exacto Knife

Skills and knowledge needed

• 3D-printing
• 3D-modeling

Technical Specifications and Assembly Instructions

1. Place 3/8" hexagon shaft through printed turbine.
2. Connect shaft to electric generator.

Cost savings

1. The micro-turbine is about $1.00
2. Cost savings depend on the size of the wheel.
3. Micro-turbine plants can cost up to $20000.^[2]
