One way to 4D print is through the use of Shape Memory Polymers (SMP). these are a type of polymer which react to an external stimulus (e.g. temperature) and subsequently change their shape in a programmed manner. Previous 4D printing research has focused on different material properties (chemistry) or geometric shape (size, thickness etc.) to control its morphing behaviour.
