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 ...

4D printing is real, happening now, and has the potential to shape the world. Self-assembly in 4D printing uses materials responding to external stimuli. A regular 3D printer can be used to create 4D ...

(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).

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 ...

A 4D printed object is like a 3D printed object, but it changes shape or self-assembles when its environment changes. [Teaching Tech] has been reading about this technology and decided to try to ...

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 ...
