Bambu Lab PLA-CF Carbon Fiber Filament 1.75mm 1KG – High Rigidity Matte Finish for Engineering and Prototyping
Bambu Lab PLA-CF is a carbon fiber reinforced PLA filament that combines the easy printability of standard PLA with significantly improved mechanical properties. The chopped carbon fibers increase bending strength by up to 68% and bending modulus by 67% compared to PLA Matte, making it ideal for parts requiring higher stiffness and structural rigidity without the complexity of engineering-grade nylons.
The carbon fiber content produces a premium matte finish with almost invisible layer lines, giving prints a professional appearance straight off the build plate. AMS compatible with low clogging risk even at high speeds. Requires a hardened steel nozzle to prevent wear.
PLA-CF Key Features
- 68% Higher Bending Strength – Significantly stiffer than standard PLA
- Premium Matte Finish – Near-invisible layer lines for professional look
- Easy to Print – Same PLA-level printability, beginner-friendly
- AMS Compatible – RFID-enabled, low clogging risk at high speed
- High-Speed Capable – Prints up to 250 mm/s
- Low Warping – Excellent dimensional stability like standard PLA
- Multiple Colors – Black, Burgundy Red, Matcha Green, Jeans Blue, Royal Blue, Iris Purple, Lava Gray

Recommended Applications
- Functional Prototypes – Parts requiring higher rigidity than standard PLA
- Structural Brackets – Mounts, clamps, and load-bearing components
- Display Models – Premium matte appearance with minimal post-processing
- Drone Parts – Lightweight yet rigid frames and mounts
- Tool Holders – Workshop organizers and custom jigs
- Enclosures – Electronics housings with professional finish
PLA-CF Printing Tips
- Hardened Steel Nozzle Required – Carbon fiber is abrasive; brass nozzles will wear rapidly.
- Dry Before Use – 55°C for 8 hours in a dryer, or 65-75°C for 12 hours on X1 heatbed.
- No Enclosure Needed – PLA-CF prints well on open-frame printers.
- Annealing Optional – 55-60°C for 6-12 hours improves heat resistance.
- AMS Auto-Settings – RFID spool auto-configures optimal parameters.

PLA-CF FAQ
Q: Do I need a hardened steel nozzle for PLA-CF?
A: Yes, the carbon fiber content is abrasive and will wear out brass nozzles quickly. Use a hardened steel nozzle in 0.4mm, 0.6mm, or 0.8mm size. Stainless steel nozzles are also not recommended.
Q: Can I use PLA-CF with the Bambu Lab AMS?
A: Yes, PLA-CF is fully AMS compatible with RFID auto-configuration. It has low clogging risk even at high printing speeds.
Q: How is PLA-CF different from PA-CF or PAHT-CF?
A: PLA-CF uses PLA as the base material, making it much easier to print (no enclosure, lower temperatures). PA-CF and PAHT-CF use nylon bases for higher temperature resistance and toughness, but require enclosed printers and are more moisture-sensitive. PLA-CF is the best choice when you need improved stiffness without the complexity of nylon-based filaments.
Q: Does PLA-CF need an enclosure?
A: No, PLA-CF has the same low warping characteristics as standard PLA and prints well on open-frame printers like the Bambu Lab A1 and A1 Mini.
Q: What build plates work with PLA-CF?
A: Cool Plate, High Temperature Plate, and Textured PEI Plate all work well. Use 45-65°C bed temperature depending on plate type.
