"ESA Develops Innovative 3D-Printed Bend-Based Mechanism"

A 3D-printed frictionless gear mechanism, designed as a compliant mechanism, has been developed to enable precise rotation in space applications. The mechanism, made of high-performance stainless steel, incorporates 24 bendable blades to reduce turning force and allow fine control of rotary motion. This innovative design eliminates the need for lubrication, reducing the risk of contamination and wear and tear. The mechanism was developed by CSEM in Switzerland and tested by Almatech SA as part of an ESA Technology Development Element activity.
