[1] The ARC Centre of Excellence for Electromaterials Science (ACES) at the University of Wollongong (UOW) is currently working on a new 4D printing project.
[2] The institution claims that it is taking 3D printing to an entirely new level with 4D printing as an unfolding technology.
[3] According to ACES professor, Marc Panhuis, researchers have started to develop 3D printed materials that morph into new structures under the influence of external stimuli, such as water or heat.
