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.

The hotend assembly doesn't secure my nozzle well. The clasp does not close easily like the original Bambu one did, and the top of the nozzle often gets slightly dislodged from the magnetic connection on one side. I've been able to successfully print some things with it on my A1 mini, which is why I gave it 2 instead of 1 stars. But from the moment I installed it, I started having nozzle temperature malfunction issues, which I never had prior to this assembly. I'll fix the issue, get a few more prints that turn out okay, and then the nozzle temp malfunction error crops up again. UPDATE: Lowered review to 1 star. After 3 months, I've still been having inconsistent issues. One of the small screws on the back of the assembly came loose and somehow fell completely out (despite the three main screws being firmly in place). I undid the three main screws, and two of the other small screws on the back fell out before I'd gotten all three big screws loose. I was excited that perhaps I'd at least found the culprit and would only need to tighten the four screws in the back. I tightened them, screwed the three big ones back in, and tried to print something only to get a nozzle temp malfuction/open circuit error. So I unscrewed the big three screws and took a look at the back so see what had happened, and the white wires in the back had pulled free, rendering the entire assembly busted and my machine unusable until a replacement part can be ordered. I thought saving a few bucks by buying a non-OEM brand assembly with free Prime shipping would be a good deal, but i wish now I'd spend the extra $10 upfront. This "deal" cost me more than that in wasted filament and time.

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.

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.

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.

This A1/A1 Mini Hot end Kit is well-built, easy to install, and delivers smooth, consistent extrusion. The all-metal stainless steel design handles high temps reliably, and the included extra silicone socks are a great bonus. Print quality improved right away—highly recommended upgrade for Bambu Lab users.
