Color Shift Luminous PLA Filament Daytime Rainbow Night Glow 3D Material

This multi-color gradient luminous PLA filament features beautiful rainbow color layers under natural daylight, and it absorbs light energy to emit soft luminous glow in dark environments, creating a striking day-and-night dual visual effect for crystal models, decorative ornaments and custom artworks. Made of high-purity PLA raw material with uniform 1.75mm diameter, this filament delivers smooth feeding, low warping and stable printing performance without nozzle clogging, fully compatible with all mainstream FDM desktop 3D printers. Each spool is individually vacuum sealed with desiccant to prevent moisture absorption and protect the luminous performance during storage and transportation; you can contact our customer service team anytime for questions about printing temperature, glow duration and color presentation.
