## Description

Unlock Advanced 3D Printing with Siraya Tech Fibreheart PET-CF Filament Siraya Tech's Fibreheart PET-CF is a cutting-edge 3D printing filament that combines the benefits of PET with the strength of carbon fiber reinforcement. Our Smart Fiber Reinforced Technology ensures optimal dispersion of chopped carbon fibers, forming a load-bearing mesh skeleton within the PET matrix. The result is a filament with exceptional mechanical properties, heat resistance, and dimensional stability. Fibreheart PET-CF demonstrates superior low creep performance thanks to PET's highly regular molecular chain structure and rigid benzene rings. Compared to PA and PC materials, it maintains better mechanical properties and resists deformation under long-term loads. Experience hassle-free printing with excellent dimensional stability - no warping, shrinking or odor. Fibreheart PET-CF is compatible with quick-remove support material for successful printing of complex models. This versatile high-performance filament is perfect for demanding applications that require both the durability of carbon fiber and the precision and chemical resistance of PET. Engineers, designers, and hobbyists alike will appreciate the strength and reliability of printed parts. For optimal results, print Fibreheart PET-CF using our recommended settings in the user guide and a hardened steel nozzle. While active heated chamber is required, it is important to have an enclosed printer. If the filament is exposed to moisture, dry in an oven at 100-120°C for 4-6 hours to restore print quality. Keep unused filament tightly sealed in its vacuum bag between uses. Choose Siraya Tech Fibreheart PET-CF for your most challenging 3D printing projects requiring strength, precision and reliability. Siraya Tech's Promise: Quality and innovation drive us. Choose Fibreheart PET-CF for reliability in your most ambitious projects.

## Features

- Enhanced Performance & Reliability: Our PET-CF filament is a high-performance composite material, expertly blending Polyethylene Terephthalate (PET) with carbon fiber. PET-CF 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’re 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.
