Abstract
A cryogenic environment implies a lot of constraints and uncertainties when it comes to the use of mechanical parts since the material properties are thermally dependent. This is even more true when the mechanical parts ensure the motion of a mechanism. In that context, the Centre Spatial de Liège (CSL) has developed a speci�ic mechanism with 3D printed parts. The Mode Selector Mechanism (MSM) is a bi -stable cryo-actuator operated at 4.2 K developed by Centre Spatial de Liège. The MSM development started as part of the far-infrared spectrometer SAFARI on the ESA/JAXA SPICA space telescope. It is taking place now in the preparation and anticipation of next-generation cryogenic missions.
