It's one of the basic facts of science: Heat something and it expands. But a team of scientists from the Lawrence Livermore National Laboratory's (LLNL) Additive Manufacturing Initiative in partnership with the University of Southern California, MIT, and the University of California, Los Angeles have gone counterintuitive and invented a 3D-printed material that shrinks when heated. Developed as part of DARPA's program to study materials with controlled microstructure architecture, the lightweight metamaterial exhibits what the researchers call "negative thermal expansion."
