Our TRI-Color Thermochromic Lava changes three (yes, THREE) different colors. Green - Pink - Yellow.

Color change occurs between 31 and 45 C. Objects are green at room temperature, and will turn a dark almost black color when refridgerated. But hold it in your hands and it will quickly go from green to brown to a beautiful bright pink. At approximately 113 F, the temperature of an average hot shower, pink transitions through orange to bright translucent yellow.

Remember Mood Rings, Mood Nails, and the fun of bohemian thermochromic body jewelry? Print something for the special lady in your life, and she'll love you forever.

Print a new thermochromic pistol grip for your Nerf gun and be the envy of your squadron.

Embed Nichrome Resistance Wire inside your prints to create invisible designs that appear with the flip of a switch.

In addition to the universe of possible aesthetic uses, many functional applications for this new filament are just waiting to be discovered.

Creates an amazing rainbow effect during printing. Yellow layers nearest the heat bed transition to pink, brown, and green in the middle of the object. (Test how good your heated build chamber really is by observing this color.) The top of the object then transitions to pink and yellow as the filament extrudes yellow from the nozzle. Makes incredible time-lapse videos!

Color change occurs in seconds! Can be heated and cooled, changing colors over and over again, thousands of times.

We only use premium clear plastic spools, so you can always see how much filament you have left. Every spool is shrink-wrapped with a desiccant packet in a re-closeable ziplock bag.

*Please note: The label on the side of the spool is incorrect. Some batches are labeled black-red-yellow, but the colors are actually green-pink-yellow. We apologize for any confusion.
