"drastically reduces vibration from flow-induced Kármán vortices caused by rotating parts... patented device produced with 3D printer... prevents damage to turbines, bridges... researchers glued the plastic-resin device that had been 3D-printed onto the trailing edge of a steel blade and ran experiments in a small-scale tunnel... there was zero vortex formation, and therefore no vortex-induced vibration... doesn't alter the blade's performance... boat propellers, turbines, hydraulic pumps"
