X1,X1C Hardened Steel Hotend Kit for Bamboo Lab X1 Carbon 3D Printer,Heating Block Replacement,High Speed,High Temp Extruder Hot End,with 0.2,0.4,0.6,0.8mm Nozzle,Thermistor,Ceramic Heater

Great value overall. It printed well right after install. Haven't had an issue yet. Don't forget to tighten the nozzle while it's hot before you start your first print.

Good quality - kit is complete - very easy to exchange nozzles

Super simple to swap the nozzle Tighten the tip before running my benchy Works perfect 👌 100% Recommend

It works ok with 0.4/0.6 nozzles, but become completely useless with the 0.2. The problem here is that the filament channel does not end up on the top of radiator like it made in original Bambu's hotend so when cutter cuts the filament it just skews and blocks/clogs the channel.

This prints as well as a stock hotend, although I have not done a flow test yet. Swapping the nozzles is relatively easy. My complaints are that a screw had not been installed, and there are no instructions. You need to remove the throat and put some thermal paste on it and reassemble everything. Not sure how the average person, who doesn’t have experience building hotends, would know that. Even just a little note to remind them would be good. You risk having thermal creep and getting a bad reputation for your hotend. All in all, I’m happy with the purchase and have enjoyed trying the different nozzles.

If you have problems, trying to get the nonsense off, hook it up to your printer and preheat it heat expands the metal as it cools it shrinks this is how you get the nozzle off

I’m not typically one to leave reviews, but hopefully I can save someone from the amount of tediousness I was just put through. I was hopeful when I saw the 4.5 Stars (at time of review), but man, this nozzle let me down. I tried so hard to blame anything but the nozzle post-install, but after unclogging it for the (at least) 5th time I had to face reality. Truth be told, I can’t even tell you what the problem is. It just doesn’t work. I took it out, unclogged it, completely cleaned it, removed and reinstalled the tip.. It momentarily produced some hair-like stringing when it was performing its best. I even put new gears in my extruder trying to rule out any other reason. I have years experience, and print near 24/7 so a cheaper alternative would have been great. Unfortunately, this just didn’t work for me. The nozzle continued to clog time and time again. Great concept, terrible execution. 2/5 Stars given rather than 1/5 because I do believe this concept could work on an item with more Quality Assurance in place. Also, I’m sure that someone has had success with it based off the reviews (assuming they aren’t locally generated). May try again in the future, but will enter with vast amounts of skepticism.

These are what should have come with stock bambu x1c Prints great Far more serviceable than the stock hotends being able to change nozzle size this way is how every other printer I have had does it
