 4. Preparing for Printing

  • Printer Compatibility: Siraya Tech ABS-CF Core is optimized for FDM printers equipped with direct drive extruders.
  • 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.

Note:

1. With optional Glue Stick or PVP glue coating for enhanced adhesion.

2. Very high speeds may affect the core-shell structure. If surface quality degrades, either increase temperature or reduce speed.

6. Moisture Management

Carbon fiber reinforced ABS filaments are susceptible to moisture absorption, which can affect print quality.

ABS-CF Core 1.75mm engineering filament

(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.
