Imagine buying an apartment.
Furniture that can be assembled by itself.
Or buy a dress online that forms in front of your living room\'s eyes.
3D printers have allowed users to print simple objects at home, but scientists are now using \"smart\" materials that can change their own shapes for 4D printing.
At present, 3D printers use nozzles to store materials in layers to create a small lifeless object, usually made of a single material such as plastic.
However, researchers now combine different types of plastics and fibers to create \"smart\" materials that change shape when they come into contact with stimuli such as heat or water.
