## Description

Fibreheart PET-CF 3D Filament - Carbon Fiber Reinforced, High Strength & Rigidity, Easy Print, Dimensionally Stable, Aluminum Foil Sealed Bag - for Strong and Precise Parts (Black, 1kg)

## Features

- Enhanced Performance & Reliability: Our PET-CF filament is a high-performance composite material, expertly blending Polyethylene Terephthalate (PET) with carbon fiber. PET-CF 3d filament maintains ease of printing, good interlayer adhesion, and good mechanical properties, and exhibits increased stiffness, improved dimensional stability, and significantly improved strength.
- Smart Fiber Reinforced Technology: Carbon fibers form a mesh skeleton structure within the PET matrix, greatly improving mechanical properties, heat resistance, and dimensional stability. Prints have no warpage thanks to internal stress release.
- Superior Dimensional Stability: PET's highly regular molecular chain structure and rigid benzene rings result in better mechanical properties and less deformation under long-term load compared to PA and PC materials.. Our PET-CF filament reduces warping and shrinkage, ensuring your prints maintain their precise dimensions and shapes, critical for functional parts and intricate designs.
- Lightweight Durability: Perfectly balancing durability with a lightweight profile, our PET-CF filament is tailor-made for applications where both strength and weight are key factors. Its low moisture absorption rate makes the part la It¡¯s an excellent material for producing robust yet lightweight components such as drone parts, mechanical assemblies, and sporting equipment.
- Versatile Applications: Whether you are a professional in need of reliable, high-strength components or a hobbyist working on detailed, functional projects, our PET-CF filament is versatile enough to meet a wide range of needs. Its ease of printing and mechanical properties make it suitable for everything from industrial prototypes to custom sporting goods.
