Color Changing 3D Printing?

Researchers are looking to bring color-changing properties to the 3D-printing process in an attempt to help reduce material waste. This is pretty hard to believe for many, but it seems pretty interesting as it will help build the consumer market.

The process uses UV light to cure a liquid resin into a solid object. But the new change is the addition of photochromic dyes. Once added to a print, the inks create a surface that turns different colors, based on the kind of light it’s exposed to. The researchers call the technology “ColorFab,” playing on a pretty standard 3D-printing naming convention.
