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, ...

Diffraction gratings are beautiful things, bending transmitted and reflected light and splitting it into its component wavelengths to create attractive iridescent rainbow patterns. It’s the same ...

Here’s another cool project out of MIT’s CSAIL labs. Researchers are looking to bring color-changing properties to the 3D-printing process in an attempt to help reduce material waste. That last bit is ...
