- GLOW PLA FILAMENT: This filament contains 30% luminous powders that emit a vibrant glow in the dark after absorbing light energy. A quick exposure to strong sunlight or UV light for just one minute activates the glow effect. However, avoid prolonged exposure to prevent damage to the filament. - PREMIUM QUALITY 1.75MM PLA FILAMENT: Designed for optimal performance, our filament features uniform winding to prevent tangling. Each spool undergoes full mechanical winding and strict manual inspections, ensuring a tidy and easy feeding experience. To maintain this, simply insert the filament end into the spool holes after each use. Enjoy strong layer adhesion for flawless first layers in your prints. - DIMENSIONAL ACCURACY: With a diameter of 1.75mm and a weight of 1kg per spool, our PLA filament is engineered for precision. Recommended extrusion/nozzle temperature ranges from 190°C to 230°C, with a dimensional accuracy of ±0.03mm. Our advanced CCD diameter measuring and self-adaptive control system guarantee a smooth and consistent printing experience, making it an ideal choice for PLA filaments. - PACKAGING: Each spool is vacuum packaged with desiccant to ensure dryness and protect against dust and foreign particles, effectively preventing nozzle jams. Applications: 1. Create stunning decorative items that glow in the dark for home decor or special events. 2. Print custom prototypes or models that require a smooth finish and strong layer adhesion. 3. Ideal for educational projects or crafts where both functionality and aesthetics are essential.
