Siraya Tech Fibreheart PAHT-CF Filament User Manual
1.Introduction to Fibreheart PAHT-CF Filament
Siraya Tech Fibreheat PAHT-CF Black is a high-performance FDM 3D printing filament specially developed for demanding applications. It is based on high-temperature nylon (PPA) reinforced with 15% chopped carbon fiber, providing excellent mechanical properties, heat resistance, chemical resistance, and dimensional stability.
2.Key Features
- Smart Fiber Reinforced Technology: Carbon fibers form a mesh skeleton structure that improves strength and releases internal stresses for warp-free printing
- Low moisture absorption: PAHT Moisture uptake is 10x lower than standard PA6 nylon for consistent performance
- Excellent wear resistance: Low friction coefficient and self-lubricating properties are ideal for gears and wear-sensitive parts
- Compatible with quick-release support material for easy printing of complex geometries

5. Tips for Best Results
- Store filament in a dry box below 15% relative humidity and reseal packaging promptly. Moisture absorption can cause oozing, bubbles, and rough surface finish.
- If material becomes damp, dry in an oven at 100°C for 4-6 hours. Only dry if filament shows signs of moisture.
- Use a hardened steel nozzle and heating block at least 12mm thick for optimal performance.
- Annealing parts at 80-100°C for 4-8 hours can further enhance strength. Allow parts to cool naturally before removing.
6. Printing Guidelines
- Nozzle Temperature: 300-320°C
- Recommended Nozzle Diameter: 0.4-1.0mm (hardened steel nozzle preferred)
- Bed Temperature: 70-90°C
- Bed Surface: PEI or PVP glue coating
- Cooling Fans: OFF
- Print Speed: 30-120 mm/s
- Retraction: 1-3mm at 1800-3600 mm/min
By following these guidelines and leveraging the advanced material properties of Siraya Tech Fibreheat PAHT-CF Black, you can achieve high-quality prints with exceptional strength, heat resistance, and wear performance for the most demanding industrial and mechanical applications.
