4D Printing with Smart Materials

Still in its early stages, 4D printing, which enables the printing of objects that can transform their shape in response to certain conditions, is opening doors to new advances in aerospace, electronics, medical, and robotics.

Using commercial 3D printers, a 4D-printed object is printed just like any 3D-printed shape. The difference is that the 4D-printing technology uses smart materials. This video highlights three applications of 4D printing.
