Device Drastically Reduces the Vibration from Rotating Parts

(EPFL, September 22, 2025)

Researchers at EPFL, led by Thomas Berger and Dr. farhat Mohamed, have created a gyroid structure that stops destructive vortex formation in fluids, overcoming a decades-old engineering challenge. This 3D-printed device dampens the vibrations caused by rotating parts such as boat propellers, turbines, and hydraulic pumps, enhancing machinery design and operation. The team tested various shapes and materials using 3D printing and settled on the gyroid, a structure known for its curved surfaces, porosity, and strength, that can effectively prevent vortices when attached to a steel blade in a wind tunnel. This innovation could allow for customized, cost-effective solutions that reduce wear and extend the lifespan of rotating machinery, with rapid prototyping and deployment advantages thanks to 3D printing.
