Sprockets from 3D printing make e-bikes whisper

Sven Weber | 21. March 2019

In the last few years, the bicycle has changed from a mere object of utility to a weight-optimized lifestyle object. Not least the electrification has contributed significantly to this trend. Customers want as quiet a run as possible. The excessive background noise of the bicycle chain on the e-bike is a thorn in the side of every passionate rider.

A metal sprocket acts as a deflection pulley on the chain to prevent it from colliding with the frame. And here the metal sprocket makes immense running noises. igus® has dedicated itself to making the bicycle run as quietly as possible. With the 3D printing service, the disturbing part was reprinted, but this time from the high-performance plastic iglidur® I3.
The chain wheels have now been in use for two months in two wheels – and the background noise is clearly minimized.

With 3D printing, igus® offers the optimum solution for printing individually manufactured drive elements such as sprockets made of high-performance plastics. The special solutions are not only lubricant- and maintenance-free, but also reduce the noise level at the same time.
