Bambu Lab PAHT-CF 1KG 1.75mm Carbon Fiber Nylon Filament with RFID – High Temp, High Strength

Bambu Lab PAHT-CF Carbon Fiber Nylon Filament 1.75mm 1KG – 194°C HDT Engineering Grade Material

Bambu Lab PAHT-CF is an engineering-grade carbon fiber reinforced PA12 nylon designed for applications requiring high strength, stiffness, and temperature resistance. With an impressive heat deflection temperature of 194°C (0.45MPa) and 50% lower water absorption than standard PA-CF, this filament maintains excellent mechanical properties even in high humidity environments. RFID-enabled for automatic settings with Bambu Lab AMS systems.

Ideal for functional prototypes, machining fixtures, injection molds, jigs, and low-volume production parts. Requires enclosed printer and hardened steel nozzle.

PAHT-CF vs Standard PA-CF Comparison

PAHT-CF Applications

• Functional Prototypes – Engineering-grade testing parts
• Machining Fixtures – Durable tooling and jigs
• Injection Molds – Low-volume prototype molds
• Jigs – Assembly and manufacturing aids
• Low-Volume Production – End-use industrial parts
• High-Temp Components – Parts exposed to heat

PAHT-CF Printing Tips

1. Dry Thoroughly – PAHT-CF is highly moisture sensitive; always dry at 80°C for 8 hours before printing.
2. Use Hardened Steel 0.6mm – Carbon fiber is abrasive; avoid stainless steel nozzles.
3. Enclosed Printer Required – High thermal insulation is essential for quality prints.
4. RFID Auto-Settings – AMS automatically configures optimal parameters.
5. Reusable Spool – High-temp resistant spool can be reused with Bambu refills.

Bambu Lab PAHT-CF FAQ

Q: Why is the HDT so high at 194°C?
A: PAHT-CF uses PA12 (long-chain aliphatic nylon) as the base material, which offers significantly higher heat resistance than standard PA6 or PA66 used in regular PA-CF filaments. The carbon fiber reinforcement further boosts heat deflection.

Q: Can I use an open frame printer?
A: No, PAHT-CF has high thermal insulation requirements during printing. An enclosed printer is essential for quality results.

Q: Why not use a stainless steel nozzle?
A: Bambu Lab specifically recommends against stainless steel nozzles. Use a 0.6mm hardened steel nozzle for optimal performance and print quality.

Q: How does PAHT-CF perform in humid environments?
A: PAHT-CF has 50% lower water absorption than standard PA-CF, maintaining excellent mechanical properties and dimensional stability even in high humidity conditions.

Q: Is the spool reusable?
A: Yes, the high-temperature resistant PC+ABS spool (90°C rating) can withstand drying without deformation and can be reused with Bambu Lab filament refills.
