Most people who design 3D printed objects want them to keep their shape as closely as possible after printing, but an emerging field known as 4D printing aims to make objects that can reconfigure themselves after fabrication. In episode 8 of the Digital Factory Podcast, we speak with Kristina Shea, professor of Engineering Design and Computing at ETH Zürich, on why self-assembly and 4D printing could be foundational design technologies in the very near future, with applications from aerospace to medical devices.
