Researchers used 4D printing to create a valve that opens and contracts according to water temperature
While 3D printing technology has proven to be a revolutionary solution with wide-ranging technological applications, a number of research teams have already begun looking beyond 3D printing, to the realm of 4D printing technology. While a number of 4D printed successes have already been achieved, researchers from the University of Wollongong in Australia have now created something very remarkable: a 4D printed a valve that automatically opens and contracts when exposed to either water or to high temperatures.
