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

I bought these for the A1. So far compatibility and performance have been identical to the original nozzle with no change in accuracy or layer lines. Everything heats up correctly and installation was easy. I can't speak as to durability since I've only completed a few print jobs so far.

The perfect spare parts. The fit perfectly. And we have had no problems with printing.

These fit and perform just like original product, fit was perfect with no heat issues. set comes with silicone nozzle sock and the best thing is price and how fast you can get the items. I have used other products from this maker, and all are a solid replacement option. Don't be afraid of trying, have used these for lots of prints and they produce exactly as expected. Each nozzle seems to be exactly like the oem can't see any difference and had to change nothing on printer, installed and went back to printing.

I DO NOT RECOMMEND!!! Nothing but problems i recommend sticking with original nozzles from bamdu or a known manufacturer gives me problems when homing clogs on nothing almost like the filament is cooling in the nozzle

These nozzles perform just like the original, but they are hardened steel, making them suitable for fiber materials. I don't plan on printing with any of the engineering fibers, but it does not hurt to have the ability. For the cost, they are excellent. Don't waste your money on "official" factory parts.
