HzdaDeve 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

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

Just bought 2 of these and tried to replace the nozzle and both stripped out and now they are junk to me and reached out to the company and told them and they never even responded to any of my texts so if I was you I would not buy from these people again. Very disappointed

These are functional. They fit on a bambu A1 as advertised. But they had some kind of coating or residue on the surface that contacts the head assembly of the printer. After a four hour print, this hotend was stuck to the print head because the residue had been burned and fused to the print head. I was able to pry the hotend off and clean the A1 print head to the point of being useable again, but it's unacceptable for a hotend to burn in place.

The fitment was wrong, so the first layer came out incorrectly. Both nozzles immediately clogged trying to print, and when trying to remove the second the clip on my A1 Mini broke. Seemed to heat fine before it broke.

Says it fits Bambu A1 and A1 mini. Well they sit in place a little loose. When doing a print and its cleaning the nozzle or bed leveling it pushes the nozzle up slightly. Then when it pushes the filament through it pushes the nozzle down which either scrapes the build plate or scrapes the print object. I had a 16 hour print fail at 80% because it kept scraping the object and knocked it off the build plate. Its when the extruder lifts and lowers the filament the nozzle goes up and down. Definitely will return and will not refer to anyone.

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.
