Description

eSUN Photochromic PLA changes color under UV. Indoors a part is one color; in sunlight it shifts to another within seconds, then back again — endlessly. It's regular PLA with a photochromic pigment, so it's just as easy to print.

The color shift is driven by UV, so direct sunlight outdoors triggers a much stronger effect than a room lamp. Over time the photochromic pigment fades a little — keep parts out of constant direct sun.

Great for toys, keychains, jewelry and novelty pieces with a wow factor. Prints on open-frame machines and holds high speeds.
