An EPFL Ph.D. student in mechanical engineering has developed a device that significantly dampens the flow-induced vibration caused by rotating parts, such as those in boat propellers, turbines and hydraulic pumps. His device can be produced with a 3D printer and has recently been patented.

It’s a classic case of beginner’s luck. Thomas Berger had just started his Ph.D. in mechanical engineering at EPFL’s School of Engineering when he made his now-patented discovery, which is published in Scientific Reports.

His thesis built on work he had started as a master’s student, but with the help of a 3D printer. This led to the promising technology that’s now attracting interest from investors.
