Toward 4D printing with structural colors

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). Nature provides many spectacular examples of ...

Lustrous-colored 3D printing using liquid crystals

What do cosmetics, car finishes, passports, bank notes, tropical insects, and oysters have in common? The color is formed through a specific microscopic organization of the matter making up the material, often called "iridescent" ...

Researchers develop simple method to 3-D print milk products

Researchers from the Singapore University of Technology and Design (SUTD) have developed a method to perform direct ink writing (DIW) 3-D printing of milk-based products at room temperature while maintaining its temperature-sensitive ...

Printing complex cellulose-based objects

Researchers from ETH Zurich and the Swiss Federal Laboratories for Materials Science and Technology (Empa) have set a new world record: they 3-D printed complex objects with higher cellulose content than that of any other ...

Erasable ink for 3-D printing

3-D printing by direct laser writing produces micrometer-sized structures with precisely defined properties. Researchers of Karlsruhe Institute of Technology (KIT) have now developed a method to erase the ink used for 3-D ...
