Researchers from the Georgia Institute of Technology (Georgia Tech) and Peking University developed a new technique, which makes good use of an LED projector and a PowerPoint slide, that makes self-folding 3D origami structures out of photocurable liquid polymers. The research team believes that this could be the first time that controlled volume shrinkage during patterned photopolymerization has been applied to create self-folding 3D origami structures. The researchers from Peking University and Georgia Tech published a paper on their research, titled "Origami by frontal photopolymerization," in the journal Science Advances.
