Renkforce RF-6838918 PLA-CF Carbon Fiber Filament 1.75 mm 1 kg Black High Tensile Strength & Stiffness

PLA-CF carbon fiber reinforced filament engineered for high tensile strength and exceptional stiffness, ideal for functional parts and demanding applications. This 1.75 mm black filament combines the ease of PLA printing with the mechanical advantages of carbon fiber, delivering professional-grade results on standard FDM printers.

Advantages

Carbon fiber reinforcement dramatically increases tensile strength and stiffness compared to standard PLA, while maintaining low warping and excellent dimensional accuracy. The matte surface finish hides layer lines for a premium appearance, and the low odor formulation ensures a comfortable printing environment. Vacuum-sealed with desiccant to guarantee moisture-free performance out of the box.

Suitable for

• Functional prototypes requiring high rigidity
• Tools, jigs, and fixtures for workshops
• Drone frames and lightweight structural parts
• Automotive components under mechanical stress
• Engineering models and end-use parts

Key specifications

• Material: PLA-CF (Polylactic Acid - Carbon Fiber)

Recommendations

Use a hardened steel nozzle to prevent abrasive wear from carbon fiber. Dry filament before printing if exposed to humidity. For best layer adhesion, print at the higher end of the temperature range and consider an enclosure to reduce warping on large parts.
