University researchers from Harvard, the University of Illinois and the University of Pittsburgh, received a grant worth $855,000 from the U.S. Army to advance 3D printing to another dimension. The group plans to develop 4D materials that can exhibit changes that occur over time. Current 3D printing technology allows the researchers to build in complicated functionality at the nano and micro levels not just throughout an entire structure, but also within specific areas of the structure. Composites can be reconfigured in the presence of different stimuli, for example.
