    Scientists report that they have developed a powerful new printer that could streamline the creation of self-assembling structures that can change shape after being exposed to heat and other stimuli. They say this unique technology could accelerate the use of 4D printing in aerospace, medicine and other industries. “We are on the cusp of creating a new generation of devices that could vastly expand the practical applications for 3D and 4D printing,” H. Jerry Qi, Ph.D., says. “Our prototype printer integrates many features that appear to simplify and expedite the processes used in traditional 3D printing...
