This is a hotend assembly kit for the Bambu Lab X1C, not just a nozzle. It pairs a TZ 2.0 hardened steel hotend with the ceramic heater and thermistor, so you can rebuild the hot end in one go rather than chasing parts individually.
What Is in the Kit
-
TZ 2.0 hardened steel hotend. Hardened steel throughout the melt zone, so abrasive filaments do not wear the bore out of shape the way they do with brass
-
Ceramic heater. The heating element that brings the hotend up to temperature and holds it there
-
Thermistor. The temperature sensor the printer relies on to read and control nozzle temperature accurately
When You Need a Whole Assembly, Not a Nozzle
A nozzle swap fixes a worn or blocked tip. It does nothing for the failures further up. If your X1C is throwing temperature errors, heating erratically or refusing to reach target, the heater or the thermistor is the usual culprit, not the nozzle. And once a hotend has been through a few clogs, cold pulls and disassemblies, the threads and seal faces are rarely as good as they were.
Replacing the heater, thermistor and hotend together removes all of those variables at once. It is also considerably less fiddly than trying to separate a seized heatbreak from a block on the bench.
Why Hardened Steel
The X1C ships with a hardened steel nozzle for good reason. If you print carbon fibre, glass fibre, glow-in-the-dark or any other filled filament, the abrasive particles cut brass surprisingly fast. A worn nozzle goes oversize gradually, so prints drift out of dimension over weeks and it is easy to blame the slicer. Hardened steel resists that wear, so this kit keeps your X1C ready for filled materials, just like the original.
Being Upfront
This is a TZ 2.0 assembly built for the X1C, not a Bambu Lab branded part. It is designed to fit and function in place of the original assembly. Fitting it is a genuine maintenance job rather than a two-minute nozzle change, so set aside some time, follow Bambu's hot end replacement procedure for the X1 series, and make sure the printer is cold and unplugged before you start.
Choosing a Nozzle Size
-
0.2mm for fine detail and small parts, at the cost of much longer print times
-
0.4mm the standard all-rounder, and the right choice if you are unsure
-
0.6mm for faster, stronger functional parts where layer detail matters less
Compatibility
Bambu Lab X1C. Not for the P1 series, A1 series or H2 series, which use different hotend assemblies. Running a P1P or P1S? Use our TZ 2.0 hotend kit for the P1 series instead.
While you have the hot end apart, a little thermal grease on the heater and thermistor seats is worth the thirty seconds it takes. Browse the rest of our parts and upgrades. Ships fast from our Sydney warehouse with Australia-wide delivery.
