SainSmart - Glow-in-the-Dark Blue PRO-3 PETG Filament 1.75mm (1kg)

Bring an enchanting luminescent effect to your functional 3D prints with SainSmart Glow-in-the-Dark Blue PRO-3 PETG Filament. Infused with high-potency phosphorescent powder, this specialty 1.75mm filament presents a clean, off-white appearance in daylight and radiates a mesmerizing blue glow in low-light environments, combining striking visual appeal with the high strength, durability, and thermal stability of PETG.

Key Advantages

• Vibrant Blue Luminescence: Stores UV and visible light energy to produce a brilliant blue glow in the dark—perfect for nocturnal markers, cosplay props, decorative art, and unique functional designs.
• Durable PETG Toughness: Combines the easy printability of PLA with the superior impact strength, weatherability, and heat resistance of PETG, producing resilient parts that hold up under stress.
• High Dimensional Accuracy: Formulated to strict ±0.02mm tolerances for smooth, clog-free material flow, uniform extrusion, and strong interlayer bonding.
• Clean Daytime Appearance: Looks like a subtle, natural off-white filament under normal ambient lighting, preserving sharp detail before revealing its vivid blue glow at night.
