Its advanced fiber mesh structure delivers superior mechanical properties and heat resistance while maintaining ease of printing and minimal warpage, making it perfect for professional-grade prototypes and functional components. ## Description 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. ## 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CSPFL7MB | | Brand | Siraya Tech | | Brand Name | Siraya Tech | | Colour | Pet-cf Black 1kg | | Customer Reviews | 4.4 out of 5 stars 210 Reviews | | Global Trade Identification Number | 00850019574630 | | Included Components | [3D Filament] | | Item Diameter | 25 Centimetres | | Item Weight | 1.2 Kilograms | | Manufacturer | Siraya Tech | | Manufacturer Part Number | PET-CF | | Material | Polyethylene Terephthalate | | Material Type | Polyethylene Terephthalate | | Model number | 3003 | | Number Of Items | 1 | | Special Feature | Carbon Fiber Reinforcement, Enhanced Strength & Rigidity, Dimensional Stability, Lightweight Durability Special Feature Carbon Fiber Reinforcement, Enhanced Strength & Rigidity, Dimensional Stability, Lightweight Durability See more | | Special Features | Carbon Fiber Reinforcement, Enhanced Strength & Rigidity, Dimensional Stability, Lightweight Durability | | Unit Count | 35.27 Ounce | ## Product Details - **Brand:** Siraya Tech - **Material:** Polyethylene Terephthalate - **Colour:** Pet-cf Black 1kg - **Item Weight:** 1.2 Kilograms - **Item Diameter:** 25 Centimetres ## Images ![Siraya Tech 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) - Image 1](https://m.media-amazon.com/images/I/713TvuvfSiL.jpg) ![Siraya Tech 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) - Image 2](https://m.media-amazon.com/images/I/71-VLQmVE5L.jpg) ![Siraya Tech 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) - Image 3](https://m.media-amazon.com/images/I/71nfIHSPvsL.jpg) ![Siraya Tech 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) - Image 4](https://m.media-amazon.com/images/I/71PLVQOZuHL.jpg) ![Siraya Tech 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) - Image 5](https://m.media-amazon.com/images/I/61sltLj0XxL.jpg) ## Customer Reviews ### ⭐⭐⭐ Review *by R***E on 18 March 2026* ### ⭐⭐⭐⭐⭐ Review *by E***C on 30 March 2026* ### ⭐⭐⭐⭐⭐ Review *by M***H on 29 March 2026* ## Frequently Bought Together - Siraya Tech 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) - Polymaker PLA PRO Filament 1.75mm 1kg, Tough & High Rigidity Black 3D Printing Filament, PolyLite PLA PRO 3D Printer Filament 1.75mm, Print with Most 3D Printers - Polymaker Fiberon PET-CF17 3D Printing Filament Black 1.75mm 0.5kg, Excellent Stable Stiffness - Fiberon Carbon Fiber Reinforced PET 3D Printer Filament, Ideal for Jigs and Fixtures --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/674044910-siraya-tech-fibreheart-pet-cf-3d-filament-carbon-fiber-reinforced](https://www.desertcart.vu/products/674044910-siraya-tech-fibreheart-pet-cf-3d-filament-carbon-fiber-reinforced) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-09*
