Siraya Tech Fibreheart ABS-CF User Manual

1. Introduction to Siraya Tech ABS-CF

Designed for hobbyists and professionals, this guide unlocks the potential of ABS-CF, a specialized filament that combines ABS's robustness with enhanced mechanical properties through carbon fiber reinforcement. With 10% chopped carbon fibers, it offers superior dimensional stability and mechanical strength while maintaining lower odor compared to traditional ABS filaments, unlike competitors using powdered recycled carbon fiber.
This material is ideal for functional prototypes, jigs, and low-volume production parts, achieving tensile strength close to 45MPa in the XY axis direction.

2. Preparing for Printing

(1) Printer Compatibility

Siraya Tech ABS-CF is optimized for FDM printers equipped with direct drive extruders, which provide enhanced filament control crucial for successful carbon fiber-reinforced printing. A harden steel nozzle is recommended.

(2) Print Bed Preparation

A clean, level print bed is essential. The recommended build plate temperature ranges from 100°C to 110°C. Compatible build surfaces include glass, and PEI film

(3) Enclosure

An enclosure is crucial for maintaining consistent printing temperatures. 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.

    4. Printing with Siraya Tech ABS-CF

    (1) Temperature Settings

    • Nozzle temperature: 250-270°C
    • Build plate temperature: 100-110°C

    (2) Print Speed

    Printing speeds can range from 30-120 mm/s. Start at lower speeds and gradually increase for optimal results.

    (3) Nozzle

    • Recommended nozzle diameter: ≥0.4mm

    (4) Retraction Settings

    • Retraction distance: 1-5 mm

    Retraction speed: 1800-3600 mm/min

    (5) Build Platform Material

    Glass, and PEI film are recommended for best adhesion with application of glue stick or coating.

    (6) Cooling Fan

    Run cooling fans at 0-30% speed to maintain print quality while ensuring proper layer adhesion.

      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 after long-term exposure to air, dry the filament at 70-80°C for 4-6 hours before printing. Only dry if the filament is damp.

      6. Additional Recommendations

      1. Keep the printer in a well-ventilated area during printing, even though this filament has lower odor compared to similar products.
      2. The Raft separation distance should be set to 0.16-0.18 mm when using support structures.
      3. For optimal results, use 100% infill with ±45° infill angles for functional parts requiring maximum strength.
