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

These are a direct replacement for the original print heads. They are printing flawlessly and appear to be very well made. No clogging or flow issues.

Works as good as the oem hot end. Ia also and to replace buffer and filament sensor at same time. Have had about 100 successful prints since replacement and have a backup now. Good value..would buy again.

I destroyed a couple of wires from the OEM heating element of my A1 Mini when I got a blob. This was a good replacement, and been working well for about 15 hours of prints. Estimated 30min install recommend Bambu official Youtube video.

Heating assembly looks like exact fit. Tightened screws on back, and front, assembled it all, haven't been able to successfully print since despite full calibration, cleaning bed, drying filament, and even increasing heat of first layer. Something is off. First layer always fails. Ordered bambu authentic heating assembly and works again.

These work really well for my Bambu A1 mini, this is my second time ordering them off Amazon much more affordable then the Bambu website and they work just as well.

So far the .2 and. 6 work great. I haven't tried any others, so no direct comparisons. The .2 nozzle seems to have more trouble with the dynamic flow calibration than the bigger nozzles. It's probably just the small size and user error. I could just manually set the pressure advance.

So I recently bought a third party hot end assembly from another seller because they could get it to me faster, but it didn't clasp right. This made me a bit skeptical about ordering another hot end assembly that wasn't OEM. However, vi am very happy to report the one from this seller works great. My printer was having really bad issues and now it's working like the day I got it. Installation was straight forward and the print quality is literally perfect. I'm not sure the original worked this will. I might dock half a star because the clasp is a little imperfect, but so was original OEM one and it's really not a huge deal. Basically, it did what I was hoping it would do and at half the price. For that, five stars. I am not associated in anyway with the seller and did not get provided anything or have anything to gain. This is a 100% unbiased review. If you're looking for a new hot end assembly, I recommend this seller.

Direct fit. Took the only one out do to a clog in the print tip that caused the heat injection bed to be incased in plastic. After I cleaned the the injection bed I realized that I bent the clip that holds the print tip to the injection bed. Thus having to purchase a new one. This part snapped right in. I was amazed how easy it was. I do recommend watching one of the Bambu Labs videos on how to change out the part. There a couple of tricks that will save you a lot of time. The switch only took 5 minutes once I watched the video.
