Looking to make your 3D prints stand out — even in the dark?
Glow-in-the-dark filaments bring a whole new level of creativity, fun, and functionality to 3D printing. Whether you’re printing for kids, home décor, or spooky gifts — glowing prints are always a hit!
Here’s how they work, where to use them, and the best design ideas for 2025.
🔦 How Glow-in-the-Dark Filaments Work
These filaments are infused with phosphorescent particles (usually strontium aluminate) that absorb light and then emit it in darkness for several hours.
⚡ Charge the print under:
- Sunlight
- LED light
- UV light (fastest charge)
🧪 Materials Available in Glow Variants

💡 Tips for Best Glow Prints
- Print with 100% infill for maximum glow
- Use a white or translucent base color to reflect light inside
- Charge under UV flashlight for faster glow
- Store in dark, cool area to preserve glow particles
- Avoid over-exposure to heat or sunlight (can reduce glow lifespan)
⚠️ Limitations
- Slightly rougher finish due to particles
- Glow intensity fades over 1–2 years
- Not food-safe (unless certified)
- More expensive than regular PLA (₹1,200–₹2,500/kg in India)
