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 ...

4D printing introduces the "time dimension" based on 3D printing, enabling printed structures to undergo controllable dynamic changes in shape, properties, or functions under external stimuli such as ...

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 ...

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 ...

(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, ...

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 ...

Stafford, England — A new manufacturing technique brings a fourth dimension to additive manufacturing through the use of "smart polymers" that can be programmed to remember shapes when they are ...
