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 ...

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 ...

A Chinese research team has developed a single-step femtosecond laser 4D printing technology that enables rapid and precise ...

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 ...

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 ...

The combination of 3D and 4D printing technologies with EMMs holds great promise for the future, driving innovation and opening up new avenues for research and development in multiple disciplines.
