This is a prototype of a mirror mount that scientists made using a new 3-D printing technique. The part at the top near the glass mirror is made of a metal with low thermal expansion, so that it won't shrink in space as much as most metals do. Using this kind of metal therefore prevents stress in the epoxy adhesive between the mirror and the metal. The bottom part of this mount is stainless steel, and could be connected to a stainless steel component of a spacecraft.
