Descrizione
Every extrusion problem eventually resolves to the same six centimetres of hardware. The hot end is where filament becomes a part, and it is the assembly that a printer's entire reputation rests on. When a machine starts under-extruding, stringing, or leaving a blob at the start of a layer, the slicer profile is usually innocent and the melt zone is usually not.
This is the complete original hot end kit for the Artillery SW-X3 Pro, SW-X3 Plus, SW-X4 Pro and SW-X4 Plus: heat sink, aluminium heater block, nozzle, heater cartridge, thermistor and fan, assembled as the unit that came with the machine. Buying it as a kit rather than as parts is the difference between one job and five, because the thermistor and heater are the two components that fail together and the two that are most often ordered wrong.
The reason to fit original parts on a printer at this price point is dimensional honesty. A nozzle that is half a millimetre too long changes the melt zone; a heater cartridge with the wrong wattage changes the heat-up curve and the PID behaviour; a thermistor with a different beta value makes the firmware read the wrong temperature with complete confidence. Any one of those turns a known-good profile into a machine that behaves like a different printer.
Replacement is a maintenance task, not a rebuild. Heat the block to printing temperature to break the nozzle free, power down and unplug before disturbing the thermistor, keep the heat break threads clean, and re-run a PID autotune after fitting the new assembly. The rest is the same calibration the machine wanted when it was new: first layer height, then flow, then retraction. Do that and the printer returns to the numbers it used to hit.
The printer is only ever as good as the melt zone, and the melt zone is a consumable.
Key Features
- Complete assembly Heat sink, aluminium heater block, nozzle, heater cartridge, thermistor and fan in one kit rather than six separate orders.
- Original Artillery part Matches the SW-X3 Pro, X3 Plus, X4 Pro and X4 Plus geometry, so the melt zone stays where the firmware expects it.
- AZ-057 and AZ-060 variants Both hot end model numbers covered for the X3 and X4 families, so the correct unit can be ordered in one step.
- Aluminium heater block Even thermal mass around the nozzle, which is what keeps temperature stable through a fast perimeter.
- Matched heater and thermistor The two parts that fail together, supplied with the correct wattage and beta value for the machine.
- Cooling fan included The shroud-side fan is part of the kit, so a cracked duct does not become a separate sourcing problem.
- Drop-in fit Bolts to the carriage with the existing hardware; no adapter plate, no firmware edit for the mount.
- Serviceable consumable Nozzles and heaters remain replaceable individually once the assembly is fitted.

Where It Belongs
This is the kit for the owner of an X3 or X4 who has already tried a profile and lost. A clogged or worn hot end, a thermistor that reads ten degrees off, a heater that no longer reaches temperature: those are the faults this replaces in one afternoon. It also suits the print farm running several X3 Pro machines, where keeping one complete assembly on the shelf turns a failed nozzle into a ten-minute swap instead of a week of waiting on parts.
Frequently Asked Questions
Q: Which model do I need, AZ-057 or AZ-060?
A: It follows the printer family. Check the model number printed on your existing hot end before ordering; if it is unreadable, tell us the exact printer model and revision and we will match it.
Q: Is the nozzle included?
A: Yes, the assembly ships with the nozzle fitted, along with the heater cartridge, thermistor and fan. Nozzles are also available separately once you are running again.
Q: Do I need to change firmware?
A: No. This is the original assembly for these machines, so the thermistor and heater are the ones the firmware already expects.
Q: How do I remove the old one without breaking the block?
A: Heat to printing temperature first so the nozzle thread releases, then power down and unplug before touching the thermistor wires. Cold disassembly is how heater blocks get stripped.
Q: Should I run a PID autotune?
A: Yes, every time the heater or thermistor changes. It takes a few minutes and it is the difference between stable temperature and a three-degree sawtooth.
Q: How long should a hot end last?
A: Depends on filament. Abrasive material wears a brass nozzle in weeks; PLA and PETG give months. Replace when flow drops at unchanged settings or when temperature stops holding through a fast layer.
Q: Can I upgrade to a different nozzle size?
A: Yes, once the assembly is fitted the nozzle is a standard replaceable item. Change one variable at a time and re-tune flow, not the whole profile.
