UAV noise is a major showstopper. Also, performing field replacement of propellers using additive manufacturing (AM) is of increased interest. In this work, we analyze experimentally the noise and performance of the same propeller manufactured through popular AM techniques, and also perform numerical experiments to isolate the effect of different parameters related to AM.
