Researchers at ETH Zurich have developed 4D printed objects that not only change their shape, but do so in a completely controlled manner that allows the researchers themselves to direct how the material reacts. The objects were developed by Kristina Shea, head of the Engineering Design and Computing Lab at ETH Zurich, and her lab. The structures are also capable of bearing weight. The ETH Zurich team is the first to create these kinds of load-bearing 4D printed structures. Read more at 3DPrint.com: http://3dprint.com/177346/eth-zurich...ed-structures/
