Perfect upgrade for abrasive filaments

I switched to this hardened steel nozzle specifically for printing carbon fiber PLA. The nano-coating seems to really help prevent clogs, and the print quality remains sharp even after several spools.

Essential for engineering materials

If you plan to print anything abrasive, get this immediately. The hardened steel saves the rest of the hotend from damage. The included sock is a nice bonus.

Durable and reliable

After months of heavy use, the nozzle shows no signs of wear. The coating definitely makes a difference compared to standard brass nozzles when printing with glitter PLA.

Good value, easy install

Installation on my P2S was straightforward. The silicone sock fits perfectly. I deducted one star only because the instructions were a bit generic, but overall a solid product.

High flow performance is real

The high-flow design allows me to push speeds higher without losing detail. Great for functional parts where time matters. Highly recommend for Bambu owners.

Solid alternative to OEM

Works just as well as the original Bambu hotend but at a better price point. The thermal transfer seems efficient, and bed leveling hasn't been affected.

5 FAQ

Q: Can I use this nozzle with standard PLA filament?

A: Yes, absolutely. While it is optimized for abrasive materials, it works excellently with standard PLA, PETG, and ABS, offering consistent extrusion.

Q: Is this compatible with the original Bambu Lab X1 Carbon?

A: This specific model is designed for the P2S, H2D, and H2S series. While the thread size is similar, we recommend checking the specific heater block geometry for the X1C before purchasing.

Q: What is the maximum recommended temperature for continuous printing?

A: While the material can withstand up to 300°C, we recommend continuous printing at temperatures below 280°C to ensure the longevity of the nano-coating and internal components.

Q: Does the silicone sock come pre-installed?

A: No, the silicone sock is included in the package separately to allow for easier installation and inspection of the hotend assembly upon arrival.

Q: How often should I replace the hardened steel nozzle?

A: Hardened steel nozzles last significantly longer than brass ones. Under normal usage, you might only need to replace it after 6-12 months, depending on the abrasiveness of the filaments used.
