Elegoo launches Fiber-Reinforced Filament Series for FDM 3D printing

The new lineup includes PETG-CF, PETG-GF, and PAHT-CF filaments.

Elegoo has introduced its Fiber-Reinforced Filament Series to enhance the performance and material options in FDM 3D printing. The new series includes Carbon Fiber Reinforced PETG (PETG-CF), Glass Fiber Reinforced PETG (PETG-GF), and Carbon Fiber Reinforced High-Temperature Nylon (PAHT-CF), each designed to offer increased strength and durability. Additional filament types are currently in development based on user input and application requirements.

According to a recent Elegoo survey, low familiarity and higher costs are the main reasons why many users have yet to try fiber-reinforced filaments.

Elegoo’s Fiber-Reinforced Filament Series

PETG-CF (black/grey): Blending the durability of PETG with the stiffness of carbon fiber, this material provides strength, rigidity, and abrasion resistance. Its low-gloss, matte finish helps reduce visible layer lines and surface wear. It is well-suited for functional parts and outdoor use, including fixtures, brackets, bicycle components, enclosures, gears, latches, and automotive or mechanical parts.


PETG-GF (black/grey/white): By infusing PETG with glass fiber, this material gains enhanced hardness and abrasion resistance, while also providing excellent electrical insulation due to the non-conductive nature of glass fibers. With a premium matte surface that minimizes layer visibility, PETG-GF is ideal for functional parts requiring both durability and insulation. Recommended applications include electrical enclosures, internal structures of industrial machinery, tooling fixtures, bicycle pedals, connectors, and abrasion-resistant terminals.

PAHT-CF (black): Made by combining carbon fiber with high-temperature nylon, this material delivers exceptional heat resistance, mechanical strength, and chemical corrosion resistance. Withstanding temperatures up to 194°C, it maintains structural integrity under thermal stress for consistent performance. PAHT-CF features excellent interlayer adhesion, abrasion resistance, and dimensional accuracy, making it ideal for high-demand applications. Recommended uses include motor housings, engine components, heat-resistant fixtures, gears, bearings, and structural or metal-replacement parts in automotive and industrial settings.
