Three-dimensional printing, also known as additive manufacturing, takes a digital blueprint and turns it into a physical object using computer-aided design (CAD). A repeating 2D structure is built up, ...

Drawing inspiration from how plants change shape in response to environmental stimuli, Harvard scientists from the Wyss Institute and John A. Paulson School of Engineering and Applied Sciences have ...

Skylar Tibbits Shares His Insights on the Biotechnology and Medical Applications of 4D Printing One of the most rapidly developing technologies that is already affecting a wide range of research and ...

(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).

(Nanowerk Spotlight) Compared to creating static objects with 3D printing, 4D printing systems add time as the fourth dimension to 3D printing: 4D printing allows a 3D printed structure to change its ...

3D printing, also called additive manufacturing, is rapidly becoming commonplace in all industries, including aerospace, automotive, medical and dental, and consumer and industrial goods. Some ...

Dr Mahdi Bodaghi from Nottingham Trent University explains why 4D printing is the new frontier in materials and manufacturing science. Imagine buying a flat sheet from a furniture store that changes ...

While we are still trying to understand the possibilities and limits of three-dimensional printing and additive manufacturing, a new term has emerged for our vocabulary. 4D printing is nothing more ...

Whilst 3D printing continues to grow in popularity, some scientists are already looking at the next step – how to make their objects transform from one shape to another using 4D printing. Essentially, ...

Using a 3D printer, people can already determine the length, width and depth of an object that they create. Thanks to research being conducted at the University of Colorado, Boulder, however, a fourth ...

Specific nerves may be stimulated artificially, for example to treat pain. The finer the nerves, the more difficult it is to attach the required electrodes. Researchers at the Technical University of ...
