Product Details

• 【Brilliant Day & Night Glow Effect】Our glow-in-the-dark PETG filament is infused with premium phosphorescent pigments, delivering a bright, translucent and high-quality glowing effect. After charging with natural daylight, sunlight or UV light, it emits vivid, clear luminescence in darkness. Your printed pieces boast sleek transparency by day and eye-catching glowing luminosity at night. Perfect for creative decor, toys, miniature models, signage, and all kinds of DIY projects that demand striking visual impact.
• 【4 Versatile Glow Color Options】This glow PETG filament set comes with four stunning phosphorescent shades: Crystal Glow Blue, Crystal Glow Green, Crystal Glow Purple and Crystal Glow Yellow. Each spool weighs 1KG. Featuring unique hues and distinct luminous performance, it supports large-volume printing and lets you explore varied glowing textures. Ideal for makers, hobbyists, artists and new 3D printing users to craft custom models, handcrafted artworks, creative gifts and home decorations.
• 【Premium PETG for Stable Smooth Printing】Made with upgraded modified PETG formulation engineered for high-precision, consistent printing. Filament diameter is precisely controlled at 1.75mm with tight tolerance of ±0.03mm, ensuring uniform extrusion and outstanding consistency across prints. Compared with ordinary filaments, this high-grade PETG offers superior layer adhesion, smooth, translucent surface finish and exceptional detail reproduction. It effectively mitigates common printing issues including nozzle clogging, air bubbles, warping, uneven feeding and prominent layer lines, drastically lowering print failure rates.
• 【Anti-Tangle Design & Wide Compatibility】Manufactured with precision mechanical winding plus manual secondary inspection, the filament is neatly arranged to prevent tangling, knotting and filament breakage during printing, delivering smooth feeding without jams. Compatible with most FDM 3D printers using 1.75mm filament. Simple and user-friendly for both printing beginners and experienced makers.
• 【Vacuum Moisture-Proof Packaging, Ideal for Gifting】Each spool is vacuum-sealed with an individual desiccant pack inside to block moisture and dust. It prevents brittleness and clumping caused by moisture absorption, preserving stable printing performance even after long-term storage. Packaged as a complete set of four popular glow colors, combining great aesthetics and practicality. It makes an excellent gift for birthdays, Christmas, holidays and anniversaries, suited for 3D printing enthusiasts, students, makers and DIY creators.

Printing UGUESS PETG

UGUESS PETG in Glow Blue runs on the PETG profile below, and this listing is a 4kg 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.
