Bambu Lab Hotend – A1 Series (A1 / A1 Mini)
The Bambu Lab Hotend for A1 Series is the nozzle + heat break + heatsink assembly that clips onto your printer’s heating assembly via Bambu Lab’s quick-swap magnetic mount. This is the thermal metal part of the hotend — it does not include the heater or thermistor (those are part of the separate Hotend Heating Assembly).
The A1 series uses a modular two-part hotend design that allows you to quickly swap nozzle sizes without tools or disassembly of the heating components.
Note: The A1 and A1 Mini use the same hotend — fully interchangeable between both models.
