Bambu Lab Hotend X1 Carbon Assembly with Removable Hardened Steel 0.4mm Nozzle Hotend for Bambu Lab X1 Series 3D Printers

Everything installed just like OEM parts with no hassle and issues, be sure to keep your hot end fan as you will need to put that onto this one! Works just as well as factory hotend as well or so that I can tell! Highly recommend this if you are in need of a hot end faster than bambu can get it to you!

I ordered two of these to replace the OEM stainless hotend, installed, and I thought everything was fine. It was not fine. During the first real print, filament started oozing from the nozzle where it screws in. This caused a buildup of filament over the ENTIRE nozzle to the point that the thermistor and ceramic heater failed, and caused the TH board (where they plug in) to fail right along with it. It took a month to troubleshoot with Bambu Labs and get a new part here.I had the second one on hand and I installed it after I installed the new TH board thinking that I had a single defective unit and there was no way another one would also have the same issue. Again: wrong. I watched the first forty seconds of the nozzles inaugural journey. Almost immediately? Oozing. I uninstalled before it could cause any real issues and will not purchase this brand again. You shouldn't either. There's a very clear issue with the quality, as I am not the only one who has experienced leaking from these hotend assemblies. Yeah, the OEM costs more. It's all one piece. That's all very annoying. But it's considerably LESS annoying (and less costly) than failed prints, lost time, and potential damage.

This hotend is the best Mod I have found thus far for a bambu labs printer by far. The ability to change nozzles quickly and to use CHT nozzles has really been a game changer for me. My print speeds have gone up a little higher. With the CHT nozzle I have been able to hit very close to 500mm/s with PLA. PLA!Given how much less it is to buy a nozzle for this hotend, vs buying a new hotend from Bambu Labs. A new CHT (high flow) nozzle is between 6 to 20 dollars (if you want a ruby nozzle its in the 20's). So $6 dollars for a new nozzle vs $35 from Bambu Labs.Setting up the hotend can be a bit of a pain in the butt, the first time (but it is exactly the same procedure if you are going to set up a new hostend from Bambu Labs. dont use too much of the heat contact paste for the heater, then slide the clip in the right orientation onto the hotend. Screw in your nozzle, then put on your sock (after you clean your hands from the contact paste). Add the fan to this hotend then you can mount into your P1S or P1P.

the ability to swap the whole hot end is great for my p1s. its great that i can swap out just the hardened nozzle

Does not print well. It leaves buildup on the models.

Honestly it was easier then it looked after I got the parts and looked at everything - finding the picture I've added made all the difference... especially since my hot end was covered in plastic and unable to see it to compare.

Perfect fitment. Quality.

I’ve bought similar hotends just like this 3 different times, and 2 of which were immediately complete busts. It honestly would be an excellent upgrade if it were just more reliable. If the pre installed nozzle didn’t straight up refuse to come out, and the machine itself not inadvertently cool down any nozzle that’s even slightly larger than the 2 included (like standard V6s), this would be great. Unfortunately, you’re practically guaranteed to waste more time and money on this than just buying and using a normal set of Bambu branded ones. I personally cannot recommend this, even if it’s tempting.
