IEMAI PETG-CF Carbon Fiber 3D Printer Filament 1.75mm, Matte Blue 1kg

Product Details

• 1️⃣【Carbon Fiber Reinforced PETG】IEMAI matte Blue PETG-CF filament is infused with 15% chopped carbon fiber. Compared to ordinary PETG, it greatly improves stiffness, structural strength, and load stability. Perfect for functional parts, brackets, fixtures, housings, and mechanical components
• 2️⃣【Reliable Dimensional Stability】With reliable dimensional stability and a diameter accuracy of +/-0.03mm, our carbon fiber PETG filament 1.75mm ensures smooth extrusion and consistent layer bonding, suitable for both beginners and experienced users
• 3️⃣【Excellent Bed Adhesion】Our carbon fiber filament provides excellent bed adhesion, which helps minimize warping and shrinkage during printing, and allows for easy printing without the need for a fully enclosed chamber
• 4️⃣【Improved Heat Resistance】Compared to standard PETG, PETG CF offers improved heat resistance and thermal stability, helping parts maintain shape under moderate heat. Suitable for outdoor components, workshop tools, and industrial or functional applications
• 5️⃣【Professional Matte Surface Finish】The PETG carbon fiber reinforced surface texture effectively minimizes visible layer lines, delivering a refined, professional matte finish, great for visible components like casings(drone casings), product prototypes, decorative parts, and mechanical covers
• 6️⃣【Wide FDM Printer Compatibility】IEMAI PETG-CF filament is compatible with Bambu Lab X1, P1, A1, and A2L series, Creality Ender, K1 & K2 series, Anycubic Kobra, Elegoo Neptune, Prusa MK3 and MK4, Flashforge Adventurer, AnkerMake M5, and more
• 7️⃣【Printing Tips & Settings】①Dry at 60°C for 5–8 hours before use; ②0.4–0.6mm hardened steel or wear-resistant nozzles; ③No enclosure required; ④Nozzle Temp 230–250°C, Hotbed Temp 60–80°C, Printing Speed ≤100mm/s

Printing IEMAI PETG-CF

IEMAI PETG-CF in Matte Blue is PETG filled with chopped carbon fiber, and this listing is a 1kg spool. The fibers make parts stiffer and more dimensionally stable than plain PETG, but they are abrasive, so a hardened nozzle is mandatory (see nozzle compatibility below). The ranges below are for PETG-CF, which usually prints a little hotter than plain PETG. PETG-CF is best suited to stiff functional parts such as jigs, fixtures and brackets that need PETG's chemical resistance. 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 carbon fiber filament guide for bed adhesion, drying, troubleshooting, and material-specific tips.

Nozzle Compatibility

Carbon fiber is abrasive and wears brass (and stainless) nozzles out of round, sometimes within a single spool. Use hardened steel or another wear resistant nozzle such as ruby or tungsten carbide. With hardened steel, start about 5 to 10°C hotter than you would with brass.

Based on Bambu Lab and Prusa guidance. More in our carbon fiber filament guide and nozzle types guide.
