Description Brahma Lab PETG Glow In The Dark Filament Brahma Lab PETG Glow In The Dark Filament allows you to create stunning 3D prints that glow vividly in the dark after absorbing light. Capable of capturing sunlight and UV light, your prints will emit a lasting glow with superior luminance. Perfect for ornaments, toys, handcrafts, and decorative applications, this filament combines reliable mechanical strength with ease of printing, making it ideal for both hobbyists and professionals. To ensure the best print quality, filaments should be dried if exposed to air for over 48 hours after opening. Glow in the Dark: Prints illuminate in the dark after absorbing sunlight or UV light, with UV light giving the highest brightness and duration. Durable & Strong: High tensile strength (51 MPa) and flexural strength (79 MPa) for robust and long-lasting prints. Heat & Thermal Resistant: Heat deflection temperature (HDT) 71°C and glass transition temperature 65°C ensure stable printing. Chemical Resistant: Excellent resistance to weak acids and bases, and deionized water, suitable for decorative and functional prints. Low Shrinkage: Mold shrinkage of 0.1–0.5% ensures precise and dimensionally accurate prints. Safe & Reliable: Flammability rated HB and excellent dielectric properties for safe usage. Easy to Print: Compatible with FDM 3D printers; recommended nozzle temperature 235–250°C and bed temperature 70–80°C. 1.75mm Diameter: Standard size compatible with most FDM 3D printers. Requires Drying: Filament should be dried at 50°C if exposed to air for more than 48 hours to maintain print quality. Wide Compatibility: Works with most FDM 3D printers for seamless printing.
