Glow-in-the-Dark 3D Printing: How It Works and What You Can Make
Glow-in-the-dark 3D prints are a fun and functional way to make your designs stand out—literally. Whether you're creating novelty items, safety signage, or eye-catching cosplay gear, glow filaments offer a unique twist with endless possibilities. In this post, we'll explore how glow-in-the-dark filament works, how to get the best results, and what you can create with it.
How Glow-in-the-Dark Filament Works
Glow-in-the-dark PLA is made by infusing standard PLA with phosphorescent materials, which absorb and store light energy, then slowly release it as a visible glow. The glow effect is most visible in dark environments and is activated by exposure to UV light—from a torch, sunlight, or even some indoor lighting.
X3D Glow PLA 1.75mm filament uses a high-quality phosphorescent additive that charges quickly and glows brightly, while maintaining the same printability you’d expect from our premium PLA.
Best Practices for Glowing Success
To get the best results from your glow-in-the-dark filament, keep these tips in mind:
-
Charge it with UV light: A UV torch works best for charging glow filament quickly. Sunlight also works but takes longer.
-
Use a thicker wall and higher infill: More material means more glow! Thicker layers allow the filament to store more light energy.
-
Avoid small, thin prints: Thin features don't store enough light to glow well.
-
Print slow and steady: Print at 30–60mm/s for better detail and stronger layer bonding.
-
No heated bed needed: But if you prefer, 50°C works well for added adhesion.
