什么是4D打印？
3D printing is still a fledgling industry, despite having been around for a while. But what is 4D printing?
4D printing technique is unfolding as a technology that takes 3D printing to an entirely new level. First invented at MIT in 2013, it consists of smart materials that adapt and re-programme their properties, functionality or shape on demand, based upon external stimuli (such as submersion in water, or exposure to heat, pressure, current, ultraviolet light, or some other source of energy).
Researchers are combining different types of PLAstics and fibres to create smart materials that self-assemble or change shape after 3D printing. Here, the fourth dimension relates to the time taken for the self-transformation.
