It may seem a touch misleading in name, but scientists at the University of Wollongong say they’re creating what they call 4D printing. The fourth dimension they refer to is time and shape shifting as the researchers have begun to develop 3D printed materials capable of morphing into new structures – post production – as those materials are influenced by the addition of external stimuli such as water or heat. The team at the ARC Centre of Excellence for Electromaterials Science say these new materials are able to transform themselves from one shape into another, and they see applications for...
