Colourbing Pre-Dried PETG Glow in the Dark Filament 1.75mm, Moisture Content <0.3%, Tough & Impact Resistant, Luminous Filament for Most FDM 3D Printers, 250g x 4 Spools - Green, Blue, Yellow, Purple

Product Details

• 4-Pack Crystal Glow PETG Filament – 1KG Total: Colourbing glow in the dark PETG 3D printer filament includes four individual 250g spools in Green, Blue, Yellow and Purple. Infused with luminous pigments, this crystal-inspired PETG filament absorbs sunlight or UV light and produces a colorful glow in darkness. Ideal for luminous keychains, identification tags, custom organizers, functional accessories, Halloween decorations and personalized gifts. Glow brightness and duration vary depending on color, light exposure and printed wall thickness
• Tough PETG Formula & Strong Layer Adhesion: Colourbing luminous PETG filament combines eye-catching glow effects with the toughness and impact resistance of PETG material. Compared with standard PLA, PETG offers better flexibility and reduced brittleness, making it suitable for functional parts, protective covers, brackets, tool holders and everyday accessories. Strong layer bonding and relatively low shrinkage help support stable printing and durable results for practical 3D printing projects
• Pre-Dried Filament & Moisture Protection: Each spool of Colourbing crystal glow PETG filament is professionally pre-dried before packaging, then vacuum-sealed with desiccant to minimize moisture exposure during storage and transportation. Proper moisture control helps reduce bubbling, stringing, popping and inconsistent extrusion caused by excess moisture. Combined with a consistent 1.75mm filament diameter, this PETG filament supports smoother material flow, reliable layer adhesion and cleaner printed surfaces
• 250g Spools & Printable Spool Adapter: Each 250g spool provides a convenient way to explore four luminous colors without purchasing multiple full-size spools. For printing systems that require larger spool dimensions, users can print a suitable spool adapter to improve compatibility and support smoother filament feeding. Adapter fit may vary depending on spool size and printer configuration. The compact spool design is ideal for multicolor projects, functional parts and creative 3D printing applications.
• Neatly Wound & Beginner Friendly: Colourbing glow PETG filament is mechanically wound and carefully inspected to ensure neat, organized filament placement on each spool. Consistent winding helps minimize tangles, knots and feeding interruptions, supporting stable extrusion throughout the printing process. Suitable for beginners familiar with PETG settings and experienced 3D printing enthusiasts, this four-color filament bundle offers convenient handling and versatile printing options for everyday projects, DIY creations and customized accessories
• Creative Gift Ideas & Professional Customer Service: With four distinctive luminous colors, Colourbing crystal glow PETG filament is a practical gift choice for 3D printing enthusiasts, makers and DIY hobbyists. Create personalized glowing accessories, holiday decorations and unique handmade gifts for Halloween, Christmas, birthdays and other occasions. For better luminous results, charge finished prints under sunlight or UV light before use.

Printing Colourbing PETG

Colourbing PETG in Glow Blue runs on the PETG profile below, and this listing is a 1kg spool. PETG is best suited to functional parts that need toughness and the light outdoor or higher-heat use PLA can't handle. 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 Bambu Lab, Prusament and Polymaker data. Heat resistance is the heat deflection temperature (HDT). Read our PETG filament 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.
