A 4D printed object is like a 3D printed object, but it changes shape or self-assembles when its environment changes. [Teaching Tech] has been reading about this technology and decided to try to ...

Have you ever imaged high-resolution 3D structures at the micro/nanoscale that react dynamically to their surroundings? The 4D printing technology is changing the game by using smart materials that ...

A recent study published in Advanced Materials introduced a 4D printing method to create tubular moisture-responsive actuators called meta biocomposites. These structures use continuous flax fiber ...

(Nanowerk Spotlight) The colors in the world around us are produced through either absorption of light by molecules (pigmentary colors) or scattering of light by nanostructures (structural colors).

A research team at City University of Hong Kong (CityU) has successfully developed the world's first-ever 4D printing of ceramics. In a paper published this August in the journal Science Advances, the ...

(Nanowerk Spotlight) Hygromorphs are materials that can change their shape or size in response to changes in humidity or moisture. They are also sometimes referred to as humidity-responsive materials ...

In the latest research in the field of materials science and engineering, researchers have made remarkable progress in the 3D and 4D printing of electromagnetic metamaterials (EMMs). This breakthrough ...

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 ...

Gutenberg’s printing press revolutionized the way the written word was replicated, bringing two-dimensional printing into the world and so vastly increasing accessibility of information. From that ...
