3-D-printed structures shrink when heated: Counterintuitive ‘metamaterial’ may enable heat-resistant circuit boards | ScienceDaily

Almost all solid materials, from rubber and glass to granite and steel, inevitably expand when heated. Only in very rare instances do certain materials buck this thermodynamic trend and shrink with heat. For instance, cold water will contract when heated between 0 and 4 degrees Celsius, before expanding.

Engineers from MIT, the University of Southern California, and elsewhere are now adding to this curious class of heat-shrinking materials.
