Bambu ASA-CF - Carbon Fiber Reinforced Filament
Material Overview
Designed for extreme environmental conditions, ASA-CF combines weather-resistant ASA polymer with carbon fiber reinforcement, delivering enhanced rigidity and dimensional accuracy. The material excels in outdoor applications requiring both durability and precision, particularly for large-format prints.
Weather and UV Resistance
ASA-CF ranks among premium materials for exterior applications, exhibiting excellent resistance to environmental degradation and ultraviolet radiation. Carbon fiber reinforcement makes it suitable for fabricating robust garden equipment, outdoor furniture components, and protective housings for electronic devices.
Dimensional Stability for Large Prints
Carbon fiber content significantly reduces thermal warping, ensuring exceptional dimensional consistency across large models or precision-critical assemblies.
Test specimen dimensions: 220×100×90mm (XY orientation)
Surface Quality
The material produces a smooth matte finish with minimal layer visibility, providing a refined aesthetic suitable for decorative outdoor elements including planters and architectural details.
Structural Rigidity
ASA-CF delivers 67% higher stiffness versus standard ASA, making it optimal for load-bearing components and applications requiring bending resistance, such as camping gear, plant supports, and outdoor furniture structures.

Technical Notes
-
Moisture Management: Pre-dry before use. Blast oven: 80°C/8h. X1 heatbed: 90-100°C/12h.
-
Material Handling: Carbon fiber increases brittleness vs standard ASA. Avoid excessive bending to prevent filament fracture.
-
Warp Mitigation:
- Utilize enclosed printer with bed adhesive
- Reduce print speed, increase bed temperature
- Reference: Common print quality troubleshooting documentation
-
Part Removal: High bed temperatures combined with adhesive create strong bonding. Allow natural cooling to room temperature before removal to prevent model damage. Reference: Post-print procedures documentation.
-
Ventilation: VOC emissions during printing require adequate ventilation. Use enclosed printers in well-ventilated areas.
