Product Description
Heating Assembly Kit for Bambu Lab A1 / A1 Mini – Composite Stone Base is a complete replacement hotend heating assembly designed for
Bambu Lab A1 and
Bambu Lab A1 Mini 3D printers. This part corresponds to the original replacement part
Hotend Heating Assembly – A1 Series, which includes a
heating block, a base with composite "stone" material, a heating element, and a thermistor.(us.store.bambulab.com)
The assembly is designed for the
quick-swap hotend system of the Bambu Lab A1/A1 Mini – a quick-release mechanism firmly fixes the heating block to the base while allowing for
simple separation of the thermal and electronic parts of the hotend for maintenance or replacement.(us.store.bambulab.com)
The heating unit can heat the hotend up to approximately
300 °C, covering common and technical filaments supported by A1/A1 Mini printers. The integrated
thermistor continuously measures the temperature and ensures stable heating regulation.
Key Features
- Complete hotend heating assembly for Bambu Lab A1 and A1 Mini
- Composite stone base – durable and dimensionally stable material for better thermal stability
- Quick swap design for easy hotend replacement without complex disassembly of the printer(us.store.bambulab.com)
- Max. working hotend temperature approximately 300 °C – suitable for PLA, PETG, TPU, ABS, and other common materials(us.store.bambulab.com)
- Integrated thermistor for accurate temperature measurement
- High-quality combination of materials: metal, ceramic, and composite stone base for efficient heat transfer and insulation(us.store.bambulab.com)
- Original dimensional compatibility for easy installation into the A1 / A1 Mini toolhead
- Ideal as a spare part in case of damage or wear of the original heating unit (e.g., after a short circuit, overheating, or mechanical damage)

Package Contents
- 1× Heating Assembly (complete hotend heating assembly)
- 3× BT3-10 mounting screw for attaching the assembly to the hotend holder
Compatibility
This Heating Assembly Kit is intended for
Bambu Lab A1 Series 3D printers:
- Bambu Lab A1
- Bambu Lab A1 Mini(us.store.bambulab.com)
It is not intended for other Bambu Lab models (P1, X1, A1 Mini Combo uses the same A1 Mini head, but the kit is specific to A1/A1 Mini).
Why Replace the Heating Assembly
Replacement of the Heating Assembly is recommended in the following situations:
- mechanical damage or cracking of the base/heating block
- repeated heating errors (failure to reach temperature, temperature fluctuations)
- damaged thermistor or heating element
- significant contamination or "baked-on" plastic on the heating block that cannot be safely cleaned
A new heating assembly restores
hotend heating reliability, which is crucial for consistent print quality on Bambu Lab A1 / A1 Mini printers.
Recommendations for Use
- After assembly, check the tightness of all screws and the correct seating of connectors.
- Perform printer calibration (especially hotend and first layer calibration) after replacing the part.
- When handling the heating assembly, ensure the printer is switched off and sufficiently cooled down.
This spare part is an ideal choice for users who want to keep their Bambu Lab A1 / A1 Mini in perfect condition and ensure a
fast, reliable, and safe replacement of the hotend heating module.
