Siraya Tech Fibreheart ABS-CF Core Filament User Manual
1.Introduction to Siraya Tech ABS-CF Core
Key Features:
Designed for hobbyists and professionals, this guide unlocks the potential of ABS-CF Core, a revolutionary filament that utilizes core-shell technology.
The unique core-shell structure maintains superior Z-axis strength compared to conventional fiber-reinforced materials. It achieves tensile strength up to 49.9 MPa in the XY axis direction.
- 20% carbon fiber Core-Shell Enhance trength & Rigidity: Reinforced with 20% carbon fiber, providing exceptional strength and stiffness, ideal for high-performance applications.
- Enhanced Layer Adhesion: Core technology improves Z-axis strength, ensuring strong layer bonding and part integrity.
- Reduced Nozzle Wear: Core-concentrated design minimizes direct contact between carbon fibers and nozzle, extending nozzle lifespan.
- High-Temperature Resistance: With a heat deflection temperature of 90°C, it maintains stability in demanding environments.
- Safer Handling: Reduced surface fibers decrease skin irritation risk, making it safer to handle.
Application:
- Aerospace: Lightweight, high-strength components for drones and UAVs.
- Automotive: Heat-resistant parts for under-the-hood applications and structural components.
- Industrial: Durable tools, jigs, and end-use parts for manufacturing.
- Consumer Goods: High-performance sports equipment and protective gear.
- Robotics: Precise, strong mechanical parts suitable for automation projects.
2. Preparing for Printing
(1) Printer Compatibility: Siraya Tech ABS-CF Core is optimized for FDM printers equipped with direct drive extruders.
(2) Nozzle Recommend: Due to its core-shell structure, it's recommended to use hardened steel nozzles.
(3) Print Bed Temperature: Print Bed Preparation A clean, level print bed is essential. The recommended build plate temperature ranges from 100°C to 110°C.
(4) Compatible build surfaces include PEI film with optional PVP glue coating for optimal adhesion.
(5) Enclosure An enclosure is highly recommended even as the core-shell technology provides improved dimensional stability. If your device has a heated chamber, maintain temperatures between 60-80°C to help release residual stress during printing and prevent warping and cracking.

5. Moisture Management
Carbon fiber reinforced ABS filaments are susceptible to moisture absorption, which can affect print quality.
(1) Storage
Store the filament in its original moisture-resistant packaging when not in use. Using a dry box with desiccant is recommended for prolonged storage.
(2) Drying Filament
If print quality degradation is observed (bubbles, stringing), dry the filament at 60-70°C for 4-6 hours before printing. Only dry if the filament is damp.
6. Additional Recommendations
1.The core-shell structure maintains stable layer adhesion even at higher printing speeds, but monitor surface quality as very high speeds can disrupt the core-shell structure.
2.The Raft separation distance should be set to 0.18-0.2 mm when using support structures.
3.For optimal results, use 100% infill with ±45° infill angles for functional parts requiring maximum strength.
4.Keep the printer in a well-ventilated area during printing, though this filament has lower odor compared to traditional ABS.
5.The core-shell technology reduces nozzle wear compared to traditional carbon fiber filaments, but hardened steel nozzles are still recommended.
