Inspired by chameleons and other colorful animals, researchers at the the University of Illinois Urbana-Champaign and Beckman Institute for Advanced Science and Technology have developed a way to 3D ...

Imagine if there were inexpensive 3D-printed sensors that changed color to show us if something had gotten too warm or was subjected to too much stress. Well, there soon could be – and they'll ...

Research conducted at the University of Vaasa paves the way for smart packaging that indicates product condition through color-changing printing inks. Doctoral researcher Jari Isohanni investigated ...

Color gradient filament is fun stuff to play with. It lets you make 3D prints that slowly fade from one color to another along the Z-axis. [David Gozzard] wanted to do some printing with this effect, ...
