3D printing has contributed to plenty of eco-friendly pursuits and artistic innovations, but one often-overlooked application of the technology is its impact on the medical field. MIT researchers have created a 3D printer that creates objects with shape memory, meaning they can take on different shapes depending on the temperature. This opens all sorts of doors for the future of biomedical devices, as well as aerospace technology. By using a 3D printing process called microstereolithography...
