Meuymeu 1KG Crystal Rainbow in the Dark PLA+ Filament, 3D Printer Filament | Crystal Rainbow luminous PLA+ Filament 1.75mm,Long-Lasting Glow, High Toughness, Fits Most 3D Printers, Best with UV Lamps

Product Details

• 【Crystal Rainbow 5 Luminous Appearance】MEUYMEU glow in the dark PLA+ combines a crystal-style Rainbow 5 appearance with a luminous effect that becomes visible after absorbing light. In normal lighting, the Rainbow 5 tone gives printed models a vivid look; in darker surroundings, the stored light adds another visual layer. This luminous PLA+ works well for dragons, hearts, roses, crystals, potion bottles, signs, masks, ornaments, fantasy figures, and display pieces where color and glow can be shown together
• 【Rechargeable Light-Activated Glow】MEUYMEU glow in the dark filament absorbs sunlight, UV light, or other strong light sources before releasing stored light in darker surroundings. For a more noticeable glow brighter effect, expose the filament or printed model to bright daylight or UV light for about 30 minutes. The perceived powerful luminescence and long-lasting glow can vary with light intensity, exposure time, wall thickness, model structure, and material amount. Additional light exposure can reactivate the luminous effect
• 【Stable Diameter & Neatly Wound】MEUYMEU PLA+ filament uses a standard 1.75mm diameter with ±0.03mm dimensional accuracy to support consistent feeding and extrusion. The spool is neatly wound to help reduce crossing, tangling, and unexpected feeding interruptions. As the filament moves toward the extruder, the stable diameter helps maintain smoother material flow. This 3d printing filament is suitable for detailed figures, articulated models, decorative parts, signs, containers, and longer print sessions
• 【1KG Spool for Larger Projects】The full 1KG MEUYMEU 3d printer filament spool provides more material for larger models, repeated projects, and extended printing without frequent spool changes. This PLA+ 3d printer filament can be used for large dragons, helmets, masks, cosplay accessories, lamps, statues, wall signs, decorative containers, and multi-part assemblies. For users who prefer one continuous color supply instead of a smaller PLA+ filament bundle, the 1KG spool is practical for large print jobs
• 【Vacuum-Sealed Packaging & Dry Storage】MEUYMEU filament PLA+ is vacuum-sealed with desiccant to help limit exposure to moisture, dust, and contaminants during transportation and storage. Properly storing the 3d printer filament PLA+ helps reduce moisture-related bubbles, uneven extrusion, and feeding issues. After opening, store the filament in a sealed container when not in use. If it has been stored for an extended period, dry it before printing to help reduce moisture-related bubbles, uneven extrusion, and feeding problems
• 【Recommended Printing Settings & Seasonal Projects】For MEUYMEU PLA+, the recommended nozzle temperature is 200°C-230°C, print speed is 0-300mm/s, and heated bed temperature is 55°C-65°C. These values can be used as starting settings and adjusted according to printer type, nozzle size, layer height, model structure, and printing environment. Crystal Rainbow 5 3d printer filament PLA+ works well for Halloween masks, glowing eyes, potion bottles, dragons, and fantasy props, as well as Christmas ornaments, hearts, stars, name signs, and personalized night-themed projects

Printing Meuymeu PLA Plus

Meuymeu PLA Plus in Glow Rainbow runs on the PLA Plus profile below, and this listing is a 1kg spool. PLA Plus is best suited to everyday parts that need a little more toughness than standard PLA, with the same heat limits. Brands and even individual spools vary, so treat these as starting points and run a quick temperature tower to lock in the sweet spot for your printer.

Ranges checked against eSUN and Polymaker data. Heat resistance is the heat deflection temperature (HDT). Read our PLA variants guide for bed adhesion, drying, troubleshooting, and material-specific tips.

Nozzle Compatibility

This listing includes glow-in-the-dark filament. The phosphorescent pigment that makes it glow is hard and wears brass nozzles quickly, even though the filament looks like ordinary plastic. Use hardened steel or another wear resistant nozzle, starting about 5 to 10°C hotter than with brass.

Based on Bambu Lab, Polymaker and eSUN guidance. More in our nozzle types guide.
