SUNLU Carbon Fiber PETG Filament 1.75mm, (4xBlack)

Product Details

• 【10% Carbon Fiber Reinforced PETG】- SUNLU PETG-CF infused with 10% carbon fiber, PETG-CF filament delivers significantly enhanced tough and rigidity compared to standard PETG. It is perfectly suited for demanding functional prototypes and end-use parts, such as drone frames, automotive components, tools, and industrial fixtures.
• 【Superior Toughness & Impact Resistance】- The short-cut carbon fiber reinforcement boosts PETG’s inherent toughness, resulting in an impressive impact strength of 19 kJ/m². This creates durable, crack-resistant prints that can withstand physical stress, making them ideal for robust structural components.
• 【Enhanced Heat Resistance (HDT: 70°C / 158°F)】- With a heat deflection temperature of 70°C, PETG-CF offers improved thermal stability and material strength while retaining the excellent impact resistance of PETG. It’s a reliable choice for parts exposed to warmer environments, from automotive interiors to outdoor equipment and garden tools.
• 【Premium Matte Surface Finish】- Carbon fibers not only reinforce your prints but also give them a distinctive, refined matte texture with a subtle grip. This dual benefit of hidden strength and a sophisticated, ready-to-use appearance is perfect for consumer products, prototypes, and any project demanding a premium look and feel.
• 【Reliable, Clog-Free Printing Experience】- Engineered for ease of use, this filament provides a smooth and consistent printing process with minimal risk of nozzle clogging or stringing. You can expect reliable production of parts with excellent rigidity, dimensional stability, and high surface quality.
• 【PETG-CF Recommend Settings】We recommend printing with PETG-CF filament at a nozzle temperature of 240-250°C, a bed temperature of 50-70°C, and a printing speed of 50-150mm/s. The filament should be dried at 70°C for 4-6 hours before use and stored in a dry environment afterward.
• 【Filament Spool Diameter】- Dimensional Accuracy +/- 0.03mm. 1KG Spool Diameter: 200 mm (7.87 inches), Spool Width: 67 mm (2.64 inches), Spool Hub Hole Diameter: 55 mm (2.17 inches). The size of the SUNLU filament spool is suitable for hanging on a lot of FDM 3D printers.
• 【Strong compatibility】- SUNLU 3D Filament is not only applicable to all SUNLU 3D printing products: FDM 3D Printer, 3D Printer Accessories, Filament Dyer, but also applicable to almost all FDM 3D printers of other brands. For example: bambu/Ender 3/Ender 3V2, etc.
• 【Vacuum Packed】-SUNLU 3D printer filaments are all vacuum sealed and come with a desiccant pack. Vacuum packing, dustproof and protect the filament dry, avoid absorbing moisture during transportation. Guaranteed to deliver the best printing effect of the filament to the hands of customers.
• 【SUNLU Main 3D Products】- SUNLU offers a variety of high-quality 3D printing products, including 3D printer filament, engineering filament,filament dryer, filament connector, 3D printer resin, resin curing box, and other accessories.

Printing SUNLU PETG-CF

SUNLU PETG-CF in Black runs on the standard PETG-CF profile below, and this listing is a 4.00kg spool. PETG-CF 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.
