IIID Max – High Speed PLA+ Glow in the Dark Filament

IIID Max – High Speed PLA+ Glow in the Dark Filament

Turn your 3D prints into glowing creations. This UV-reactive PLA+ filament charges in sunlight or under UV light and glows brightly for hours in the dark. Available in Neon Green and Neon Sky Blue — two vivid glow colors that create eye-catching results for cosplay props, kids' room decorations, safety markers, and novelty items.

Engineered for high-speed printing up to 300mm/s on modern printers like Bambu Lab and Creality K1, this glow filament delivers the same reliable print quality as our standard PLA+ line — consistent diameter, vacuum-sealed packaging, and smooth extrusion.

Key Specifications

How Glow in the Dark Filament Works

The filament contains strontium aluminate phosphorescent pigments embedded in the PLA+ base. These pigments absorb light energy (sunlight, UV, or bright indoor light) and release it slowly as visible glow. A 5–10 minute charge under direct light produces hours of glow. The glow is brightest in the first 30 minutes and gradually fades.

Pro Tips

Glow filaments are abrasive due to the phosphorescent particles. Use a hardened steel nozzle (not brass) to avoid premature wear. Print at 0.2–0.3mm layer height for maximum glow intensity — thicker walls let more light charge deeper into the part. For the strongest glow, print with 3+ perimeters and 30%+ infill. Neon Green glows brighter than Sky Blue in most conditions.

Best Applications

Cosplay armor and props, Halloween decorations, kids' night lights and toys, glow-in-the-dark signage, safety markers for stairs and switches, party decorations, and novelty gifts.
