2 Pack A1 Mini/A1 Hotend Print Head Hot End Kit Extruder Upgrade High-Temperature 0.4MM Hardened Steel Nozzle Replacement with 4PCS Silicone Cover Sock for Bambu Lab 3D Printer Accessories

works with the a1! love that the heads are changeable.

Got these to replace the factory one on mh Bambu A1 mini when it got blocked up and damaged. I've printed quite a bit with these so far, and it's working really well, even getting some fine details I wouldn't expect out of this size nozzle!

These HotEnds are a PERFECT replacement...! some of the best replacement hardened nozzles I've found for 3D printing. The hotends are a perfect fit and the results after using are just what I was hoping for. I have used the hardened 0.4mm replacement and now i am planning to order the rest of the sizes for my Bambu A1. Could not be happier with this company's customer service as well. Also, delivery was very quick.

Have not been running this very long but I’ve definitely seen some improvement

The nozzle does not put out a consistent stream. The print quality is terrible.

Works good so far. Time will tell.

The fit is good and my first few prints with them have gone well. I had issues jamming on the 0.2 hotends before and I am hoping that these might be less prone to that issue, or at least easier to clean. So far very happy with the results.

These worked really well with my A1 Mini.
