Researchers Create Shape-Shifting Objects with New 4D Printing Method

We've written about 4D printing before, but the objects printed by researchers at the Georgia Institute of Technology, Singapore University of Technology and Design, and Xi'an Jiaotong University are a little bit different from most of the other 4D printed objects we've seen before. The researchers at the three institutions created their shape-shifting objects by 3D printing them from multiple reactive materials, each designed to respond differently to a heat stimulus.
