Propeller is very familiar to every family. But little is known about the production process. And the method of copying 3D propellers is one of the most important stages of the process. Propeller is a highly balanced product. So the design thinking here is, design a wing and multiply that wing into the desired number. Another important note is that the thickness of the rotor surface is not equal, so it is not possible to use evenly spaced design, which is also the most misleading point of the fan blade design. And if there are errors then you need to fix the design and then repair the molds, edit the processing ... To overcome the above errors you should apply 3d scanning technology - reverse design to design fast, accurate, copy sample rotor
