Researchers have developed a technique that programs 2D materials to transform into complex 3D shapes. University of Texas at Arlington researchers have developed a technique that programs 2D ...

Wherein most 3D printers are designed to create objects that have to remain rigid in structure and shape, 4D printing, as it is called, allows the 3D printed objects to change their shape and ...

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 ...

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.

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

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 ...

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.

This KS2 maths article explains how to sort 2D and 3D shapes according to their properties using Carroll diagrams and Venn diagrams, ... Slide 1 of 3, Five 2D shapes in different colours: ...
