Bambu Lab Hotend P1P/P1S Assembly with Removable Hardened Steel 0.4mm Nozzle Hotend for Bambu Lab P1 Series 3D Printers

This replacement worked as advertised. I experienced no issues.

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.

I do not own a Bambu printer but wanted to try this style hotend on my Ender 3(2018). Of course I had to do some custom wiring but it has been a night and day difference from the stock style hot end. I wish I would have did this mod sooner

works perfect on p1s ez enough to slap the heater in.

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.

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!

The item on the left is from the factory, as I removed it from the package. The heating element and thermistor wires are supposed to run up the middle, like you see with my stock Bambu hotend.What you see in the hotend that I purchased is the wrong side is facing in this direction.I know I can take it apart and switch it around but should I have to do that? No.If the part can leave the factory literally backwards is it likely to be generally of poor quality? Yes.I'll have to return this and buy the real thing, unfortunately. It's not worth interrupting production.

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