4D printing is real, happening now, and has the potential to shape the world. Self-assembly in 4D printing uses materials responding to external stimuli. A regular 3D printer can be used to create 4D ...

As a society we are constantly revolutionizing the materials we use. We have created 3D printers that print out digital shapes for us and now we have created printers that produce materials capable of ...

Three-dimensional printing, also known as additive manufacturing, takes a digital blueprint and turns it into a physical object using computer-aided design (CAD). A repeating 2D structure is built up, ...

We have all heard of 3D printing, but have you heard of 4D printing? Probably not. 4D printing takes the same technologies of 3D printing, but with a slight change, objects printed in the fourth ...

(Nanowerk Spotlight) Compared to creating static objects with 3D printing, 4D printing systems add time as the fourth dimension to 3D printing: 4D printing allows a 3D printed structure to change its ...

The days when 3D printing was simply dreamed about are far behind us. Today, the process of creating a three-dimensional object via successive layers of materials is a mainstream activity—from ...
