Product description

The original Bambu Lab Hotend Heating Assembly – FAH049 is a complete heating assembly for 3D printers Bambu Lab P2S (P2 Series). It is a part mounted on the print head responsible for heating the hotend to printing temperature and enabling quick hotend replacement thanks to the integrated clamping mechanism.

The assembly combines a heating cartridge and temperature sensor into one compact unit. This ensures stable and repeatable temperature regulation, which is crucial for a quality first layer as well as long print jobs. It is an ideal original spare part in case of failure or loss of performance of the original hotend heating.

Key advantages

• Original Bambu Lab part (FAH049) – full compatibility with P2S printer mechanics and firmware.
• Quick hotend replacement – the assembly uses a clamping mechanism for easy maintenance.
• Stable temperature – heating cartridge and sensor in one unit for consistent print results.
• Minimizing downtime – quick repair in case of heating failure, without the need for tedious tuning.
• Safe operation – precise temperature measurement helps protect the printer from overheating.
• Simple installation – supplied with mounting screws, installation according to Bambu Lab Wiki instructions.

Suitable use

This part is intended especially for situations where:

• there are hotend heating failures or unstable temperature increases,
• the printer reports temperature sensor / heating cartridge errors,
• the entire heating unit replacement is necessary due to damage or wear,
• you want to have a spare assembly in stock to minimize printer downtime.

Installation (brief guide)

Always follow the detailed official procedure in the Bambu Lab documentation (Wiki) for P2S.

1. Turn off the printer and disconnect the power. Wait until the hotend has completely cooled down.
2. Access the print head – remove the cover according to the manufacturer's instructions.
3. Disconnect the connectors from the existing heating assembly.
4. Dismantle the old unit – unscrew the fastening screws.
5. Install the new Hotend Heating Assembly FAH049 in place of the original.
6. Screw in using the supplied screws (M2.5×5) and carefully connect the connectors.
7. Turn on the printer and perform a hotend heating test (short preheat / wipe) and check for any error messages.
