Fremover – HighSpeed PLA+ Mystery Glow in the Dark (w/ Glitter)

Fremover – HighSpeed PLA+ Mystery Glow in the Dark with Glitter

Glow meets sparkle. The Fremover Mystery Glow combines glow-in-the-dark phosphorescent pigments with embedded glitter particles for a dual visual effect — prints shimmer under light and glow in the dark. Available in Mystery Blue and Mystery Neon Green, each color reveals a unique combination of glow and sparkle that you won't find in standard glow filaments.

The "Mystery" name comes from the multi-layered visual effect: under normal light you see the glitter sparkle, in low light the glow emerges, and in complete darkness the phosphorescent glow takes over. It's three looks in one filament.

Key Specifications

Mystery Blue vs. Mystery Neon Green

Mystery Blue has a cool-toned sparkle under light with a blue-white glow in the dark — ideal for space-themed prints, ocean-inspired designs, and fantasy props. Mystery Neon Green delivers a warm sparkle with a classic bright green glow — the go-to for Halloween projects, toxic/radioactive themed builds, and maximum visibility in the dark.

Pro Tips

The glitter particles add extra abrasion beyond standard glow filament. A hardened steel nozzle is essential — brass nozzles will wear out within 1–2 spools. Use a 0.5mm or 0.6mm nozzle for best results; the combination of glow pigments and glitter can restrict flow in 0.4mm nozzles. Print at 210–220°C for optimal flow and sparkle visibility. The glitter effect is most visible at 0.15–0.2mm layer heights.

Best Applications

Fantasy and sci-fi cosplay props, custom jewelry and accessories, party decorations, holiday ornaments, kids' toys with dual visual effects, decorative vases and planters, custom phone cases, and any project where you want both daytime sparkle and nighttime glow.
