Glow in the Dark PLA Filament — Bright, Consistent, Reliable
Most glow-in-the-dark filaments are gimmicky — weak glow, abrasive particles that destroy brass nozzles, and wildly inconsistent diameter. Forgely's glow-in-the-dark PLA is different. We blend photoluminescent pigments into our ±0.02mm tolerance PLA base, delivering a bright, long-lasting glow without sacrificing the print quality and consistency Forgely is known for.
Our glow PLA charges quickly under UV or bright ambient light and holds its luminescence for hours. The phosphorescent particles are evenly distributed throughout the filament — no clumping, no hot spots, no sections that glow brighter than others. This means your prints glow uniformly across the entire surface, whether it's a cosplay accessory, a light-switch cover, or a decorative piece.
Like all Forgely filament, our glow-in-the-dark PLA is lot-tracked, manufactured in Utah, and priced at $16.99/kg. We recommend using a hardened steel nozzle for extended printing, as the phosphorescent particles are mildly abrasive over time.
Why Choose Forgely
- ±0.02mm tolerance — consistent diameter even with glow particles blended in. No jams from particle clumping.
- Even particle distribution — uniform glow across your entire print, not patchy bright and dark zones.
- Lot-tracked batches — consistent glow intensity across spools from the same production run.
- Made in Utah — quality-controlled domestically. Ships next business day.
FAQ
Do I need a special nozzle for glow-in-the-dark filament?
We recommend a hardened steel nozzle for extended use. The phosphorescent particles are mildly abrasive and will wear a brass nozzle over time (typically after 2-5kg of printing). A hardened steel or ruby-tipped nozzle eliminates this concern entirely. For occasional prints, a brass nozzle works fine — just inspect it periodically for bore widening.
How long does the glow last after charging?
Forgely glow PLA reaches peak brightness after 5-10 minutes of exposure to UV light or 20-30 minutes under bright ambient light. The initial bright glow lasts 15-30 minutes, fading to a visible afterglow that persists for several hours in a dark environment. Thicker walls and lighter-colored base prints glow brighter and longer.
Can I print glow-in-the-dark filament at high speeds?
Yes. Our ±0.02mm tolerance holds even with the phosphorescent additive, so you can print at your normal PLA speeds (typically 60-150mm/s depending on your printer). The glow particles don't affect melt flow at standard PLA temperatures of 210-220°C. Use the same settings you'd use for regular Forgely PLA.
