We've wrote articles before about large 3D Printed structures, but how about smaller parts? A team from both Peking University in China and the Georgia Institute of Technology have created a unique way of 3D printing complex self-folding origami-like structures using a conventional light projector and PowerPoint slides. Simple right? The technique is called the “frontal photo polymerization method,” and could be used for making of microelectronics, soft actuators, mechanical metamaterials, and biomedical devices.
