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 ...

It might seem like there’s a typo in the title, but 4D printing stocks are a real industry emerging right now. But what is 4D printing, other than just 3D printing in an extra dimension? Well, in this ...

(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).

A joint research team led by Dr. Dong-Gyun Kim of the Korea Research Institute of Chemical Technology (KRICT), Professor ...

Every year, millions of tons of sulfur quietly pile up as waste from petroleum refining. For decades, this yellow element has ...

A joint research team has developed the first 4D printing technology built from industrial ...

4D printing adds a new dimension to the process: time. Whereas 3D printing technologies allow users to construct a 3D product, 4D technologies allow a 2D product to gradually change its shape over ...

Marc del Pozo Puig of the Eindhoven University of Technology (TU/e) has created a new 'smart ink' for use in 4D printing. 4D printing uses 3D printing to create objects capable of rearranging ...

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 ...

A decade ago, 3D printing was the hottest buzzword on the planet. Investors piled in… and 3D-printing stocks took off like a rocket. 3D Systems DDD — a leading 3D-printing company at the time — soared ...
