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

Works as intended. The only hasttle is that you need to keep changing it, from detail, to big prints.

This worked perfectly fine for what it is. I will say it was a bit of a chore getting all the extra bits installed. In the future I would probably purchase a fully assembled hot end. As for the hot end itself, it works great and is good quality, fits well, and seems to be OEM

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.

Hot end was package well and was as described. I have yet to use it on my machine.

What can I say, it's Bambu. Works perfectly.

Had used the 0.4 nozzle, but wanted more details in my miniature models. This is purchase was definitely worth it.
