eSUN PLA-Luminous Cored Blue is a glow-in-the-dark PLA filament for FDM 3D printing, supplied in 1.75mm diameter with a 1kg net weight. It features a vivid blue appearance and a luminous effect in low-light environments after exposure to light, especially ultraviolet light, while maintaining excellent PLA printability for toys, decorations and creative models.
⭐ PLA-Luminous combines easy PLA printing with vibrant colors, high-intensity luminous power and a distinctive glow-in-the-dark appearance.
Compatible with FDM printers that support PLA, 1.75mm filament and nozzle temperatures up to 230°C, including printers from:
✅ Bambu Lab ✅ Creality ✅ Prusa ✅ Anycubic ✅ ELEGOO ✅ Other Brand
🔹 Suitable for open and enclosed printers; PLA does not require an enclosed build chamber.
🔹 eSUN officially lists PLA-Luminous as AMS compatible. Glow materials are abrasive and can accelerate wear in feeding components; Glow PLA is not recommended for AMS Lite.

💡 Recommendations and Usage Conditions
🔹 eSUN recommends using a wear-resistant nozzle such as hardened steel because luminous material is abrasive.
🔹 Neither the current eSUN product page nor TDS Version 4.0 specifies a drying recommendation for this material.
🔹 Luminous intensity depends on the strength and duration of light exposure; longer irradiation improves the glow effect.
🔹 Store the filament in a dry and sealed environment with desiccant after use.
