3D-Fuel - Pro PCTG-CF10 Carbon Fiber Filament 1.75mm - 1kg

Upgrade your functional 3D prints with 3D-Fuel Pro PCTG-CF10 Carbon Fiber Filament. Reinforced with 10% chopped carbon fiber strands, this high-performance engineering composite combines the incredible impact toughness, high chemical resistance, and low hygroscopic nature of Pro PCTG with the structural stiffness, dimensional stability, and matte surface finish of carbon fiber. Engineered for demanding industrial environments, PCTG-CF10 delivers superior interlayer bonding and up to 50% greater impact resistance than standard PETG-CF composites.

Key Features

• 10% Carbon Fiber Reinforcement: Chopped carbon fiber fibers increase tensile strength, structural rigidity, and heat deflection while reducing part weight and thermal expansion.
• Exceptional Impact Toughness: Modified molecular structure with cyclohexane dimethanol (CHDM) provides 20% to 50% higher impact resistance than PETG, preventing brittle failure under high-stress conditions.
• Superior Chemical Resistance: Resists chemical degradation, stress cracking, and swelling when exposed to alcohols, hydrocarbons, mild acids, industrial degreasers, and automotive oils.
• Low Moisture Absorption & High Stability: Absorbs significantly less ambient moisture than PETG or nylon composites, preserving dimensional stability and print quality in humid operating environments.
• Matte Aesthetic Surface Finish: Carbon fiber reinforcement hides print layer lines, producing a smooth, matte finish suitable for end-use functional parts, drone frames, and automotive jigs.
• Automatic Material System (AMS) Ready: Ships on a durable spool designed for seamless compatibility with multi-material systems like the Bambu Lab AMS.

Hardware & Printing Guidelines

• Hardened Nozzle Required: Carbon fiber is abrasive. Print using a hardened steel or ruby-tipped nozzle (0.4mm or larger) to prevent rapid nozzle wear.
• Enclosure Optional: Prints reliably on open-frame printers without thermal warping, though a draft-free environment helps optimize layer adhesion on large parts.
