PC+CF (Polycarbonate + Carbon Fiber) is a high-performance engineering composite designed for both FFF (Fused Filament Fabrication) and FGF (Fused Granulate Fabrication) 3D printing. By combining the outstanding strength and heat resistance of polycarbonate with the rigidity of carbon fibre reinforcement, PC+CF delivers exceptional mechanical performance, dimensional stability, and lightweight durability. It is widely used for aerospace, automotive, robotics, industrial tooling, and high-performance engineering applications.

PC+CF is one of the most advanced 3D printing materials for industrial additive manufacturing, offering an excellent strength-to-weight ratio and superior thermal stability. Carbon fibre reinforcement significantly increases stiffness while reducing deformation during printing, allowing manufacturers to produce lightweight yet robust components. Available as both filament for FFF printers and pellets for FGF systems, PC+CF enables the production of precision engineering parts as well as large-format industrial components with consistent quality and long-term reliability.

Why Choose PC+CF for 3D Printing?

PC+CF is engineered for applications requiring exceptional structural strength, rigidity, and thermal performance. Compared to standard polycarbonate, carbon fibre reinforcement enhances stiffness, improves dimensional accuracy, and reduces warping during printing. These properties make PC+CF an ideal choice for demanding industrial environments where lightweight, high-strength components are essential.

Compatible Printing Technologies

PC+CF is fully compatible with both industrial additive manufacturing technologies offered by GFac.

FFF (Fused Filament Fabrication)

FFF technology uses PC+CF filament to manufacture highly accurate engineering components with excellent surface quality and mechanical performance. It is ideal for functional prototypes, structural parts, manufacturing fixtures, robotics components, and low-volume production where precision and durability are critical.

FGF (Fused Granulate Fabrication)

FGF technology processes PC+CF pellets, enabling manufacturers to produce large-format components at higher printing speeds and lower material costs. It is particularly suitable for automotive tooling, aerospace structures, industrial moulds, marine applications, architectural components, and heavy-duty manufacturing where lightweight strength and productivity are priorities.

Both technologies provide outstanding mechanical performance, allowing manufacturers to select the most suitable process based on production volume, part size, and application requirements.

Common Applications

PC+CF is widely used across industries requiring lightweight, high-strength, and heat-resistant components.

Typical applications include:

• Functional engineering prototypes
• Aerospace components
• Automotive structural parts
• Manufacturing fixtures and jigs
• Robotics and automation systems
• Industrial tooling
• Mechanical brackets and supports
• Machine components
• High-performance engineering assemblies
• Large-format industrial parts

FFF vs FGF Printing

Storage and Best Practices

PC+CF can absorb moisture over time, which may affect print quality and mechanical performance. Store both filament and pellets in a sealed container with desiccant in a cool, dry environment. Dry the material before printing if moisture exposure is suspected. For optimal results, use an enclosed printer or heated build chamber to improve temperature stability and reduce warping. Because carbon fibre is highly abrasive, a hardened steel, tungsten carbide, or ruby nozzle is strongly recommended to minimise nozzle wear and maintain consistent extrusion throughout long production runs.
