Shrinking When Heated

Most things expand when heated (the one notable exception is cold water).

A team at MIT led by Nicholas Fang has created a 3D printed material (made using copper and certain polymers) that shrinks.

The primary use is actually heat proofing in certain applications. It can be tuned to certain temperatures, and may be used in building bridges, in making microchips that lose less performance as they heat and even in dental fillings.
