ETH Zurich scientists create load-bearing and predictable 4D printed objects, take '4D printing' a step further

With 3D printing now over three decades old, a growing number of researchers are looking ahead at the next logical step: “4D printing” is the popular science term for 3D printed objects that transform over time. Not just any random transformation, 4D printing is so innovative precisely because of its design parameters. Structures are pre-programmed to respond especially to a stimulus. While 4D printed materials such as shape memory alloy and electroactive polymers have been paving the way for some time, a group of scientists at the Swiss Federal Institute of Technology Zurich (ETH Zurich) have been pushing the […]
