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

Ordered these new nozzle to replaced the original jammed one on my Bambu Labs A1 3D printer.Fits perfect and love that they included the silicon covers, as my original had ripped. Snapped right into place and locks in perfectly.Printing has been great. Works just as the original did, printing smooth and efficiently.Very happy with the quality and output from these replacements. Nice to have another as backup, as they are an item that eventually needs replacing. In the future, I'll have extras on standby so there's no downtime.

I’m new to 3DP and after a few dozen small prints, got cocky and sent a print job without checking in on it. When I came back home the print head was completely gummed up with a ton of melted filament. Apparently midway thru the print there was a bed adhesion issue and the print moved and stuck to the print head.Uug, I had to clean all the filament out and in the process rubbed the nozzle - having this new set delivered quickly was awesome! I works great

These worked great for me in my Bambu A1, since it's been very hard to find genuine replacement hot ends for it. I put these in, and they're just as easy to install as the genuine manufacturer parts from Bambu. I would recommend this for anyone who prints a lot, since these seem to be just as good quality as the name brand version.

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

Had no issues with my OG Bambu hot ends. Threw one of these ones on today. NO GO. Nozzle clogged instantly and gave feeding issues. Feed kept clicking like a clog or jam even though filament was barely coming out. Did some trouble shooting, put the OG Bambu back in. Worked fine. Put one of these hot ends back on and again issues. So it’s the hot ends not me. I don’t recommend. For a few buckaroos more I’m going to get the Bambu brand. I learned my lesson.

Work amazingly well. I kept getting flow error messages with the Bambu hardened 0.4 nozzle. These work perfectly, especially with the carbon fiber filaments that were problematic with the Bambu nozzle. Zero issues with accuracy of prints.100% would recommend these nozzles.

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.

We run a small print farm and these are the go to for us. High build quality. Never had a problem and they install just like factory. Hardened nozzles run great. Great value for the money.
