3D-printed Structures Shrink when Heated

12.01.2018 tribonet 36 Views
Counterintuitive “metamaterial” may enable heat-resistant circuit boards. 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 […]
