Individual bucket for pelton wheel impulse water turbine
Depending on the type of plastic used to print this bucket (and the scale/power of the pelton wheel), it is perhaps unlikely that the finished bucket will be made of plastic. However, these prints would used to create a mold, from which a metal or resin pelton bucket would be cast. Some hand finishing may be required to smooth the surface of the cups, depending on the resolution of your printer.
Object can be scaled according to power requirement of pelton wheel, flow rate and pressure of water jet.
This design is based on the work of Somjit Uppamatho
