If you're wondering what your students will be creating next... how about these 4D printed aquatic forms. In 4D printing we have the usual three dimensions, plus an additional dimension of movement (in this case enabled using pneumatic inflation in water. "They can respond to external forces such as gravity, water ripples or currents, and interaction with people or other 3D prints in real life," Hone said. "Their man-made composite materials behave uncannily similar to living organisms." Right now they're mostly eye-candy, but no doubt useful applications for 4D printing will be found.
