SUNLU Glow in The Dark PETG/PLA Filament – Light Up Every 3D Print

Turn your 3D prints into glowing centerpieces. The SUNLU 1KG Glow in The Dark PETG/PLA Filament is designed for makers who want more than just functional parts – they want models that come alive when the lights go out. Whether you’re printing cosplay props, night lights, toys, or display pieces, this luminous filament absorbs light and releases a magical glow in the dark, all while delivering the reliability and precision SUNLU is known for.

🌟 Why You’ll Love It

• Stunning glow-in-the-dark effect – Both PETG and PLA options contain 10% phosphorescent powder that charges under light and glows for about 10 minutes in dark or low-light environments, perfect for eye-catching prints.
• High precision, smooth printing – With a filament diameter of 1.75mm and tight ±0.02mm tolerance, you get consistent extrusion, clean details, and fewer print failures.
• 100% bubble-free formulation – Engineered to be 100% bubble-free, reducing stringing, weak spots, and surface defects for stronger, smoother parts.
• Neatly wound for tangle-free feeding – SUNLU’s 100% neatly wound filament technology means no knots, no random overlaps, and fewer jams, improving printing efficiency and reliability.
• Optimized for speed – Wide printing temperature ranges allow 50–200 mm/s speeds (depending on material and temperature), so you can print fast without sacrificing quality.
• Excellent printer compatibility – Designed to fit most FDM 3D printers with 1.75mm filament, including BambuLab, Raise3D, Creality, Anycubic, ELEGOO, and more – compatibility rate up to 99%.
• Versatile material choices – Choose PETG for tougher, more temperature-resistant parts, or PLA for easy printing and crisp detail – both with the same luminous effect.
• Long spool length – Each 1kg spool offers approximately 330m of filament, giving you plenty of material for large projects or multiple glow-in-the-dark prints.
• Flexible bed setup – Print with or without a heated bed: use adhesive on a cold bed, or print without adhesive at 70–80℃ for strong adhesion and easy removal.
• Factory-direct quality – Produced by SUNLU’s own ISO9001, SGS, and TUV certified factory, ensuring consistent quality, reliable performance, and strong pre- and after-sales support.
