eSUN PLA-CF Black Carbon Fiber 3D Printing Filament 1.75mm 1kg

eSUN PLA-CF Black is a carbon-fiber-reinforced PLA filament for FDM 3D printing, supplied in 1.75mm diameter with a 1kg net weight. It combines high rigidity and excellent printability with a deep matte black finish and distinctive carbon-fiber texture, making it suitable for jigs, brackets, structural parts, functional prototypes and engineering applications.

⭐ PLA-CF combines the printability of PLA with high rigidity, carbon-fiber reinforcement and a matte finish, with officially documented high-speed printing capability up to 500 mm/s.

Compatible with FDM printers that support PLA-CF, 1.75mm filament and nozzle temperatures up to 230°C, including printers from:

✅ Bambu Lab ✅ Creality ✅ Prusa ✅ Anycubic ✅ ELEGOO ✅ Other Brand

🔹 A wear-resistant nozzle such as hardened steel or ruby is recommended because carbon fiber is abrasive.

🔹 AMS Lite and AMS 2 Pro do not officially support third-party carbon-fiber filament such as eSUN PLA-CF, while AMS HT can route it through the bypass outlet.

🔹 Creality CFS supports PLA-CF subject to spool-dimension compatibility, while eSUN PLA-CF is not recommended for CFS Lite.

🔹 Official Anycubic information for ACE 2 Pro is conflicting regarding fiber-reinforced materials, so compatibility with eSUN PLA-CF should not be assumed without system-specific confirmation.

🔹 Official compatibility of eSUN PLA-CF with the original AMS, ACE Pro and MMU3 could not be sufficiently verified, so support is not assumed.

⭐ Why Choose eSUN PLA-CF?

🔹 Reinforced with short carbon fibers to increase rigidity and improve structural and functional part performance.

🔹 High flexural modulus helps resist deformation in brackets, fixtures and load-bearing components.

🔹 Excellent printability with low shrinkage and a distinctive matte carbon-fiber texture.

🔹 The non-glossy surface helps reduce visible layer lines and gives printed parts a professional engineering appearance.

🔹 eSUN officially documented ePLA-CF high-speed printing capability up to 500 mm/s.

🔹 Black appears as a deep neutral black with a matte carbon finish and fine textured surface, with significantly less reflection than glossy black PLA.

⚙️ Printing Settings

💡 Recommendations and Usage Conditions

🔹 If printing performance decreases, eSUN recommends drying PLA-CF at 40°C for more than 4 hours.

🔹 Use a hardened-steel or ruby nozzle because carbon fiber can accelerate wear on conventional nozzles and extruder gears.

🔹 PLA-CF is stiffer than standard PLA; avoid sharp bends and excessive resistance in the filament path to reduce filament breakage.

🔹 Store the filament in a dry, sealed environment with desiccant after use.
