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.

I recently replaced the stock hotend on my 3D printer with the Bambu Lab P1 Complete Hotend Assembly and I’m genuinely impressed with the difference it’s made in my prints. Installation was straightforward, and once installed it delivered consistent extrusion and improved overall performance. What stood out most was how reliably it handled a variety of filaments — from PLA to more demanding materials — without clogging or inconsistent flow. The hardened steel nozzle feels solid and durable, and the precision it provides really shows up in finer details and smoother surfaces. Print quality seems more consistent than before, and I’ve had fewer failed prints since swapping to this assembly. I also appreciate that this is a complete assembly, so I didn’t need to worry about sourcing separate components like the heater block or thermistor — everything came together and worked straight away. For anyone running a Bambu Lab P1 or compatible printer, this feels like a worthwhile upgrade or spare part to keep on hand. Overall, it’s a dependable, well-built hotend that provides reliable performance and great print quality across a range of materials. ✔ Recommended for hobbyists and pros alike who want smoother prints and fewer issues.

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.

happily surprised that mine came with a fan and the works on it. this was not expected, and almost certainly a mistake. Thanks tho!

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