Perfect for abrasive filaments

I switched to this hardened steel nozzle to print carbon fiber PLA and it works flawlessly. The installation on my A1 mini took less than 5 minutes. No clogs so far after 20 hours of printing.

Essential for A1 owners

If you plan on printing anything other than basic PLA, get this immediately. The hardened steel prevents wear and tear. My prints look just as good as they did with the original nozzle.

Great upgrade, slightly slower heating

The build quality is excellent and feels very durable. I noticed it takes about 10 seconds longer to reach target temperature compared to the brass stock nozzle, but the longevity makes up for it.

No more stripped threads

My old brass nozzle got damaged after trying to clear a jam. This hardened steel version is much more robust. Printing TPU has never been smoother on my A1.

Seamless replacement

Fit perfectly on my Bambu A1. The silicone sock included fits snugly. I appreciate that it comes as a full hotend assembly, making the swap incredibly easy without needing to disassemble the whole head.

Solid performance

Works well with glass-filled nylon. The only reason for 4 stars instead of 5 is the price point, which is a bit high compared to third-party options, but the guaranteed compatibility is worth it.
