Siraya Tech Fibreheart PET-CF
Carbon-Fiber-Reinforced for Strong, Precise, and Stable Prints
Siraya Tech Fibreheart PET-CF is a carbon-fiber-reinforced PET filament that delivers strong, lightweight, and dimensionally stable prints. Its fiber mesh structure enhances stiffness while reducing warping and shrinkage, ensuring precise, reliable results. Easy to print and highly durable, it’s ideal for both professionals and hobbyists needing consistent high-strength parts.
Key Features of the Siraya Tech Fibreheart PET-CF Filament:
- Carbon fiber–reinforced PET for increased strength and stiffness
- Smart fiber mesh structure improves mechanical performance
- Reduced warping and shrinkage for superior dimensional stability
- Lightweight yet durable material for functional components
- Suitable for both professionals and hobbyists with reliable printability
Carbon Fiber Reinforcement
Carbon fibers form a mesh skeleton structure to greatly improve mechanical properties, heat resistance, and dimensional stability. Prints have no warpage due to internal stress release.
- Ease of printing for heat resistant & exceptionally durable prints
- Increased stiffness and dimensional stability
- Perfect for reliable, high-strength components

Printing Tips
- Storage: Although PET has very low moisture absorption, it is still sensitive to humidity. Store in a sealed package with desiccant for best results.
- Drying: If moisture is notable, dry at 90°C for 4-6 hours. Find filament dryers here.
- Annealing: For enhanced hardness, consider annealing at 90 - 100°C for 4-6 hours. Be mindful of shrinking due to the annealing process.
