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

The original clip that holds the nozzle on my A1 broke, so I bought this HzdaDeve assembly to replace the entire heating component. I’ve put 76 prints on it so far, and it’s working perfectly. The installation was straightforward and it feels just as high-quality as the factory part. The heating is consistent and I haven’t had any thermal runaway errors or issues with the nozzle seating. If you had a hardware failure on your hot end or just want a reliable spare to keep your machine running, this is a solid choice.

I used this hotend kit on a modded Elegoo Carbon Centauri and it worked perfectly. Everything fit well and installation was straightforward. One of my favorite features is the quick swap nozzles — it makes switching between different nozzle sizes fast and hassle-free. Having multiple sizes included (0.2, 0.4, 0.6) is a big plus. The hardened steel nozzles are a huge benefit. They give me the confidence to print abrasive and higher-temperature filaments without worrying about wear. Overall, a solid upgrade that performs exactly as expected.

Watch a short YouTube video on install but it fits perfectly and works just as an OEM part. Printer was back up and running in no time

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.

Great product, I’ve continually swapped these out between .2 and .4 and I’ve had no issues yet with jamming or it getting stuck. These will be my go to when buying new ones, once needed. I’ve probably put 400+ hours on the nozzle without issue.

Overall assembly and installation of the product was simple. It fit well for my Bambu Lab A1. However, after using it for a week, the printer regularly pauses because of a temperature malfunction error. This was the problem that this kit was supposed to solve. Luckily the issue does not cause any major issues with printing, but it does require consistently checking the printer or the app to resume the print after it pauses due to the error. Though cheaper than an original one from Bambu Labs the inconsistency with the printing did not make it worth it. I will be buying an official one from Bambu Lab to replace this one and I'll keep this one as an emergency spare. Initial Review: 2 Stars UPDATE: The seller reached out and offered a full refund for my purchase, since this hot end failed to work with my Bambu A1 printer. For that reason I have updated the stars to reflect the seller standing by their product. Updated Review: 4 stars.

Fit great on the A1 mini and print quality is the same as the original, and is a much better value the the official replacement

Originally I thought this was junk because after auto bed level, the nozzle would scratch the build plate. I thought it was a manufacturing flaw that made it too long. However, turns out it was my machine. the three black screws on the backside of the heating assembly was loose, which caused this hotend to droop down. Once I tightened the screws, this hotend and nozzle worked perfectly.

Absolute Waste of money, after 2-3 hours of printing both my printer has clogged extremely and had to change the Hotend Heating Assembly to fix the printer costed around 5-6k
