PCTG-CF – Carbon Fibre Enhanced PCTG Filament

3DEA’s PCTG+CF combines the versatility of PCTG with 15% carbon fibre to create a material with great rigidity. Compared to pure PCTG filaments, the carbon fibre reinforced filament has higher tensile strength, making it ideal for 3D printing enthusiasts and professional users (including engineers and designers) who want to combine performance with technical excellence. In addition to high tensile strength and rigidity, PCTG+CF is characterised by good resistance to chemicals and temperatures.

Due to its low shrinkage, this material is perfect for printing precise models with intricate geometries while achieving a stunning carbon fiber finish.

Tip: PCTG+CF can be used in unenclosed 3D printers, making it highly versatile for various applications.

Application Areas:

• Prototyping: Ideal for functional prototypes and rapid prototyping processes.
• Automotive Industry: Suitable for fasteners, component covers, vehicle interiors, and spare parts production.
• Production Maintenance: Used for manufacturing spare parts, machine components, and metal part replacements.
• Small Series Production: Perfect for electronic housings, complex geometric elements, and custom parts.

This filament combines strength, precision, and aesthetic appeal, making it an excellent choice for demanding applications.

• Diameter: 1.75mm ± 0.03mm
• Print Temp: 250-280ºC
• Hot Bed: 80-100ºC (required)
• Surface: Glue Stick, PEI, Tape
• Notes: Due to the strong adhesion to the bed, it is not recommended to print directly on its surface or on glass. This can lead to damage. We recommend using a masking tape or glue sticks.

PCTG is an upgraded variant of PETG, offering enhanced strength, toughness, and clarity, with significantly higher impact resistance—achieving an impressive 90 KJ/m² in the Izod test (notched sample) compared to PETG’s 5-8 KJ/m²—making it ideal for applications requiring durability and resilience. It also boasts superior chemical resistance, optical properties, and temperature tolerance (up to 76°C), all while retaining ease of printing.

Printing Recommendations:

• First Layers: Disable your part cooling fan for the initial layers to enhance adhesion and minimize warping, especially for larger prints.
• Surface Preparation: A PEI sheet or glue stick application is recommended to ensure a strong bond with the print bed.
• Hot Bed: Maintain a consistent bed temperature to reduce warping and improve layer adhesion.

Features of PCTG:

PCTG is part of the copolyester family, known for its improved mechanical properties over PETG. Its high impact resistance makes it an excellent choice for functional parts, prototypes, and end-use components. Despite its toughness, it retains a glossy finish, which enhances the aesthetics of printed parts.

PCTG shares PETG’s ease of printing but offers improved durability, making it less prone to wear and deformation under stress. It is also more forgiving to print, handling temperature fluctuations better without compromising quality.
