0.4mm Hotend Kit for Bambu Lab A1/A1 Mini, 3D Printer Parts Replacement Print Head for Bambu Lab A1/A1 Mini 3D Printer

funciona perfecto con la A1, no percibo diferencias entre esta y la original, y el precio es perfecto

Was cheaper than buying at Bambu and works the same, worth the buy

Excellent hot end replacement. My factory bambu unit was unrepairable and this got me back up and running. As close to the original as you could hope for at a fraction of the price

These may LOOK like a great alternative. Do not be fooled. These are complete trash. They will work flawless for about 5-10 prints, then the neck will cram and filament will spew out of the top of the neck in between the heat sink and the nozzle neck. Once this is done, I have not been able to remedy this issue. I have tried hot pull, cold pull, lancing with the nozzle cleaner, nothing works and now they are completely toast. The filament will have this greasy oil in it and be SUPER hard to clean off. Don't waste your time, just buy the real one. Lesson learned. I bought 3, gave one to a friend and the other 2 both took a crap - the SAME issue with both. The silicone sleeve is mega flimsy, but that is whatever. Lastly, the replaceable hot nozzle ends are SUPER hard to get on or off. The first one I almost stripped the entire thing due to how hard it was on there.TLDR: Complete junk after about 5 prints. Buy from Bambu to save hassle.

Works great on my A1, I have had zero issues with it for the past 60+ hours of printing. During installation make sure to screw the tips in all the way, though. (I have only used the 0.4mm tip, but I assume the others are both good quality too).

Good

I have bought Bambu brand nozzles before and these are every bit as good. Same quality for less. I print almost daily and have had zero issues.

My 3rd nozzle from this vendor--works awesome, not a single problem ever.
