We've heard of 3D printers being used to draw in 2D, but what about taking a 3D model and transforming it into a 2D template? That's what a group of researchers with the Institute of Science and Technology (IST) Austria are attempting to do in their research on self-actuating objects, which are essentially flat materials that use material forces to transform themselves into a 3D object. The group of current and former IST Austria computer scientists not only figured out a way to create smooth, self-actuating, free-form objects, they also developed a unique material design and a new self-transformation method.
