iSANMATE PLA luminous rainbow filament 1.75mm 1kg rolls

NEW - Glow-in-the-dark filament is like any standard filament but with one key difference: It glows after being charged with light.

This effect is achieved by additives such as strontium aluminate (and sometimes zinc sulfide and calcium sulfide), which absorb UV light and re-emit it as visible light. You’ll find glow-in-the-dark variants of PLA, and they’re the perfect way to add a glowing effect to a decorative or cosplay print!
