• 【Glow in the Dark PLA】SUNLU glow in the dark PLA filament contains phosphorescent materials, which can glow in the dark after absorbing light energy. If it is exposed to UV lights, the luminous effect will be better.
• 【Ultra-Bright & Long-Lasting Glow】- Engineered with premium Strontium Aluminate, SUNLU PLA glow in the dark 2X brighter and lasts significantly longer. Perfect for Night-navigation tools and Safety markers that need to remain visible for hours in total darkness.
• 【High-Strength & Non-Brittle Formula】 - SUNLU Luminous PLA enhances toughness, ensuring your functional tools—like camping zipper pulls or gear tags—don't break under pressure. Flexible yet durable.
• 【Clog-Free & Nozzle Friendly】- Dimensional Accuracy +/- 0.02mm, Optimized particle distribution prevents clogging. While we recommend hardened steel nozzles for all luminous PLA, SUNLU filament's smooth flow minimizes wear, ensuring consistent precision for high-detail prints.
• 【Versatile Utility Applications】- Beyond just toys & halloween decoration! Ideal for Outdoor/Camping gear, Emergency signs, Tactical markers, and Dark-environment tools. Your prints will be as practical as they are eye-catching.
