Official Bambu Lab Hotend with Nozzle - X1 Series and P1 Series Compatible with P1S P1P X1C X1 Carbon 3D Printer (.4mm Hardened Steel)

It worked on my x1c. Quick and easy, no issues.

Great quality.

I had partial clogs in my 4mm nozzles that I couldn’t clear for the life of me. Print quality was still good enough, but it’s getting warmer now and my printer is in the garage, so they were starting to cause jams when I’d print parts with lots of retractions. I tried all of the methods, cold pulls, using the needle to try to clear them out, the works. Whatever I’d try, I’d just get the curling filament from the tips. This all stemmed from printing with CF PETG in a hot room. Anyway, they got so bad that I decided to just replace them. I was going to order directly from Bambu, but with shipping charges it would have cost to $30 and they always take a week to get things to me. For just a couple of dollars more, I could get one of these the next day so I ordered one. It came packaged in a Bambu box and looked exactly the same as any that I’ve bought directly from them. I swapped the parts over from one of these clogged hot ends to this one and tested it out. It worked perfectly, exactly like it is supposed to. These are considerably more expensive than buying them directly from the company if you’re buying more than one or if you order enough other stuff to get free shipping, but if you only need one and you want it delivered quickly this is the way to go.

Comes with no replacement wires also the second print with this hotend gave me this. I'm definately certain this is a manufacturing defect

It fits perfect in my P1S and and includes thermal paste for the heat sink and sensor. Easy install and very durable. It printed CF Nylon like nothing. Great product
