Meuymeu 1KG Light Rainbow in the Dark PLA+ Filament, 3D Printer Filament

Product Details

• 【Crystal Rainbow Luminous Effect】 MEUYMEU glow in the dark PLA+ combines a crystal rainbow appearance with a luminous effect that becomes visible in darker surroundings after absorbing light. The colorful look of this rainbow PLA+ gives printed models a distinctive appearance during the day, while the glow adds another visual effect after the lights go down. This rainbow filament is suitable for dragons, fantasy figures, stars, moons, signs, decorative vases, ornaments, masks, and display models. The full 1KG spool also provides enough material for larger creative projects or repeated printing
• 【Light-Absorbing Glow Effect】MEUYMEU glow in the dark filament can absorb sunlight, UV light, or other strong light sources before releasing stored light in darker surroundings. For a more noticeable glow in the dark effect, expose the filament or printed model to bright daylight or UV light for about 30 minutes. Stronger light and sufficient exposure can help make the luminous appearance more visible. Wall thickness, model structure, and material usage may also influence brightness and glow duration. The glow gradually fades over time and can be reactivated through additional light exposure
• 【Consistent Diameter & Smooth Feeding】MEUYMEU PLA+ filament features a standard 1.75mm diameter with ±0.03mm dimensional accuracy to help maintain stable feeding and consistent extrusion. The spool is neatly wound to reduce crossing, tangling, and unexpected feeding interruptions during printing. As the filament unwinds, it feeds steadily toward the extruder for a smoother printing process. The combination of consistent diameter and organized winding makes this 3d printing filament suitable for detailed models, long print sessions, and larger glow-themed projects
• 【More Material for Larger Prints】The full-size 1KG MEUYMEU 3d printer filament PLA+ spool provides more material for large models and extended printing sessions without frequent spool changes. This PLA+ 3d printer filament can be used for large dragons, fantasy statues, moon lamps, star decorations, masks, cosplay accessories, signs, decorative containers, architectural pieces, and multi-part models. Crystal Rainbow color adds more visual variety to larger surfaces, while the glow effect makes the finished project more noticeable in low-light environments
• 【Moisture-Protected Packaging】 MEUYMEU filament PLA+ is vacuum-sealed with desiccant to help limit exposure to moisture, dust, and contaminants during transportation and storage. Keeping the 3d printer filament properly stored helps reduce moisture-related bubbles, uneven extrusion, and feeding issues. After opening, store the filament in a sealed container when not in use, and if it has been stored for an extended period, dry it before printing to help maintain stable performance
• 【Recommended Printing Settings】 For MEUYMEU PLA+ filament, the recommended nozzle temperature is 200°C-220°C, printing speed is 0-300mm/s, and heated bed temperature is 0°C-60°C. These values can be used as a starting range and adjusted according to printer type, nozzle size, layer height, model structure, and printing environment. Crystal Rainbow glow in the dark filament works especially well for Halloween ghosts, pumpkins, skulls, magic-themed decorations, Christmas stars, ornaments, fantasy creatures, and nighttime display pieces. The combination of rainbow filament color and luminous effects also makes it suitable for creative 3d printing filament projects
