Although 4D printing is considered very promising for various biomedical applications – such as tissue scaffolds, neural scaffolds, grafts and stents, cardiac patches and valves, even bionic ...

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 ...

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 ...

Repairing and reusing plastics and delivering cancer drugs more effectively are only two of many of the potential applications a new 3D/4D printing technology might have, thanks to the pioneering work ...

4D printing develops materials that can change properties and characteristics based on changes in the environment—like temperature. The changes could let materials self-assemble thus speeding up ...

(Nanowerk Spotlight) The next generation of robots may not look anything like the rigid, mechanical machines we’re used to. Instead, imagine a robot that moves more like an octopus or a human hand, ...

Researchers worked to revolutionize 4D printing by making a 3D fabricated material change its shape and back again repeatedly without electrical components. Reversible 4D printing technology could ...

The aviation industry faces multiple pressures from higher fuel costs and increased scrutiny over the environmental and quality-of-life impacts from its aircraft. Researchers are looking for new ...

In CNC milling, the so-called “4th axis” is rotation of either the tool or the part around the other. In additive manufacturing techniques, like 3D printing, the angle at which a material is deposited ...

It wasn’t so long ago that 3D printing was the new kid on the block. Now the term 4D printing is making headlines, stretching our ability to conceptualize once again. To understand 4D printing, it ...
