Materials that controllably change shape over time – often called four-dimensional (4D) materials – are excellent candidates for advanced tissue engineering applications. Many 4D materials, however, ...

Scientists printed tissues in their final shape, hoping they would work like natural organs. But this approach failed to copy the active shaping that happens during early development.

As they told the Harvard Gazette, “the new method [of 3D printing responsive 4D materials] opens up new potential applications for 4D printing technology, including smart textiles, soft ...

By mimicking the way orchids, calla lilies and other plants bend and twist, scientists have created shape-shifting "4D-printed" structures that they say could one day help heal wounds and be used ...

This study developed a 4D-printed tubular biocomposite designed for precise moisture-triggered shape changes. The goal was to create sustainable, programmable actuators for applications like solar ...

Scientists are developing 4D printing technology to pave way for 'smart' materials that can change shape by themselves. LONDON: Imagine buying a dress online that takes shape in front of your eyes ...

Here comes 4D: Shape-shifting objects that fold themselves up and change over time are created using a printer. The technique uses a 'hydrogel ink' that swells when it is added to water; ...

Italian researchers have created a novel 4D-printed biodegradable soft robot shaped like a seed that changes shape in response to changes in humidity and can navigate through the soil.
