ASA-CF Print Settings

Expert-recommended ASA-CF (ASA) settings for all Bambu Lab printers

Why use ASA-CF?

  • Carbon fiber reinforced ASA for maximum outdoor structural rigidity
  • UV-resistant AND stiff — ideal for drone frames, automotive parts
  • Professional matte finish from carbon fibers
  • Better dimensional stability than standard ASA
  • Excellent strength-to-weight ratio for outdoor applications

What are the best ASA-CF print settings?

Use default Bambu Lab temperature profiles for ASA-CF. Recommended outer wall speed is 130 mm/s.

What nozzle size should I use for ASA-CF?

fine0.4mm

0.4mm hardened steel REQUIRED

medium0.4mm

0.4mm hardened steel nozzle

coarse0.6mm

0.6mm hardened steel

How do I dry ASA-CF filament?

Dry ASA-CF at 70°C for 4-6 hours. Moderate moisture absorption — CF fibers increase sensitivity

What support material should I use with ASA-CF?

Recommended: ASA-CF base + HIPS interface

Base: Same as model (ASA-CF) | Interface: HIPS (dissolvable in limonene)

ASA-CF as bulk support with HIPS at interface. CF texture helps base supports break away; HIPS interface dissolves cleanly.

~30% less HIPS filament used

Expert Tips for ASA-CF

  • Hardened steel nozzle is mandatory — carbon fibers are extremely abrasive.
  • Enclosure strongly recommended for ASA-CF.
  • The combination of UV resistance + CF stiffness makes this ideal for outdoor structural parts.

Alternatives to ASA-CF

PETG-CF

If you want a CF option that's easier to print without a full enclosure

Trade-offs: Less UV-resistant than ASA-CF. Different surface texture

PLA-CF

If you need the easiest CF experience and parts stay indoors

Trade-offs: No UV resistance. Lower heat resistance. More brittle
