Product Description
15% Chopped Carbon Fiber Reinforced
Uses Siraya Tech’s proprietary fiber reinforcement technology to control fiber dispersion, forming a mesh structure that improves mechanical properties, heat resistance, and part dimensional stability with no warping.
PET-CF vs PETG-CF:
Siraya Tech Fibreheart PET-CF is a high-performance material that should not be confused with PETG-CF. While both contain carbon fiber reinforcement, PET-CF offers superior mechanical properties, heat resistance, and dimensional stability compared to PETG-CF. PET-CF is an ideal choice for demanding applications that require higher strength, stiffness, and precision.
Compared to PAHT-CF, PET-CF demonstrates better resistance to moisture and lower creep tendencies. PET’s highly regular molecular chain structure and rigid rings result in less deformation under long-term loads, making it an ideal choice for applications requiring consistent performance in varying environmental conditions.
Dimensional Stability
PET-CF filamentcom bines ease of printing and strong interlayer adhesion with increased stiffness and enhanced strength for superior dimensional stability.
No Warping, Shrinkage
Carbon fibers in the PET matrix enhance mechanical strength, heat resistance, and dimensional stability, preventing warping.
Dry only when moisture is evident. If over-dried, the material may become brittle.
Vacuum Aluminum Foil Packaging 
Storage and Handling
Although PET has very low moisture absorption, it is still sensitive to humidity. Store unused Siraya Tech Fibreheat filament in sealed packaging with desiccant. 90°C for 4-6 hours. Only dry if filament shows signs of moisture.
Cautions for Use: AMS NOT Compatible.
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.
