Move on over 3D printing, because 4D printing is taking the spotlight. (WATCH FULL VIDEO BELOW, transformation near end of clip) Scientists at Harvard University created a new 4D printing method— ...

During the early stages of life, organs do not just appear in their final form. They take shape through a process of controlled bending, twisting, and folding. These changes help cells organize into ...

Drawing inspiration from how plants change shape in response to environmental stimuli, Harvard scientists from the Wyss Institute and John A. Paulson School of Engineering and Applied Sciences have ...

With 4D printing, the objects can change shape or properties using external stimuli such as temperature, light, pH, magnetic field, electricity, and moisture. Additionally, the changes in shape or ...

Enter 4D materials, which are like 3D materials, but they change shape when they are exposed to specific environmental cues, such as light or water. These materials have been eyed by biomedical ...

Combining materials with different swelling ratios creates structures that transform into tubes when exposed to water. (Courtesy: Yu Bin Lee) Materials that controllably change shape over time – often ...

Nowadays, 3D printing allows items to be created from a wide variety of materials — plastic, ceramic, glass, metal and even stranger ingredients such as chocolate and living cells. The machines work ...

New work out of Georgia Tech promises to lend a sense of permanence to shape-shifting 3D printing. The technology, commonly referred to as 4D printing by those in the know, aims to add another ...

It takes a lot of money to launch stuff into space — even by NASA terms. The cost ranges from around $9,000 to more than $40,000 per pound. With that sort of price tag, weight and space are at a major ...

New hydrogel-based materials that can change shape in response to psychological stimuli, such as water, could be the next generation of materials used to bioengineer tissues and organs, according to a ...
