Bambu Lab Hotend Heating Assembly for X2D Right

The Bambu Lab Hotend Heating Assembly for X2D Right is an original replacement component designed specifically for the right auxiliary hotend of the Bambu Lab X2D dual-hotend toolhead.

Installed on the right side of the toolhead, the assembly is responsible for heating the auxiliary nozzle to the required printing temperature. Stable heating is essential for consistent filament melting, reliable extrusion, and accurate temperature control during single-material, multicolor, and multi-material printing.

The FAH058 assembly is the dedicated right-side version and should be used when replacing a damaged or malfunctioning original right hotend heating assembly.

Key Features

• Original Bambu Lab replacement heating assembly

• Part number FAH058

• Designed specifically for Bambu Lab X2D

• Dedicated to the right auxiliary hotend

• Responsible for heating the right nozzle

• Supports the X2D dual-hotend printing system

• Integrated hotend clamping mechanism

• Direct replacement for the original right-side assembly

Dedicated Right Auxiliary Hotend Heating

The X2D uses separate heating assemblies for its two hotends.

The FAH058 is specifically designed for the right auxiliary hotend and supplies the heat required to bring its nozzle to the selected extrusion temperature.

Reliable heating helps maintain:

• Consistent filament melting

• Stable material flow

• Accurate extrusion

• Reliable layer formation

• Consistent printing temperature

Designed for the X2D Dual-Hotend System

The Bambu Lab X2D uses independent left and right hotends within the same toolhead.

The right auxiliary hotend can be used as part of workflows involving different:

• Filament colors

• Material types

• Support materials

• Nozzle configurations

• Printing requirements

Because the two sides use dedicated components, the correct left or right heating assembly must be selected when carrying out repairs.

Quick Hotend Clamping Mechanism

The heating assembly secures the compatible hotend using a clamping mechanism.

This allows the hotend itself to be removed for maintenance or replacement while the heating assembly remains installed within the toolhead.

The design helps simplify routine hotend servicing and replacement.

Stable Temperature Control

The heating assembly works together with the printer's temperature-control system to heat the right nozzle and maintain the selected printing temperature.

Stable thermal control is important for preventing issues such as:

• Inconsistent extrusion

• Poor layer bonding

• Temperature fluctuations

• Failed heating

• Interrupted prints

• Material flow variation

Right Side Only

FAH058 is specifically the right auxiliary hotend heating assembly.

It should not be confused with the separate left-side assembly:

• Left Main Hotend Heating Assembly – FAH057

• Right Auxiliary Hotend Heating Assembly – FAH058

The two components serve different positions within the X2D toolhead and should not be assumed to be interchangeable.

Useful Replacement Part

Replacement may be appropriate if the right hotend develops symptoms such as:

• Right nozzle not heating

• Slow heating

• Unstable nozzle temperature

• Heating-related printer errors

• Intermittent heating

• Physical damage to the heating assembly

• Damage following a filament blob or toolhead failure

Correct diagnosis should be carried out before replacing the component because similar symptoms can also originate from wiring, connectors, temperature sensing, or toolhead electronics.

Direct Replacement Component

The FAH058 is supplied as the right-side heating assembly, allowing the affected component to be replaced without replacing the complete X2D toolhead.

It is useful as a replacement or spare part for:

• X2D owners

• Print farms

• Workshops

• Schools

• Service centres

• Businesses operating multiple X2D printers

Package Includes

• 1 × Bambu Lab Auxiliary Hotend Heating Assembly – Right

Installation Note

Switch off the printer and disconnect it from power before replacing the heating assembly.

Allow the hotend to cool completely before beginning service.

During installation:

• Confirm that the replacement component is FAH058

• Confirm that you are servicing the right auxiliary hotend

• Remove the required toolhead covers

• Disconnect the original heating assembly carefully

• Avoid pulling directly on electrical wires

• Install the replacement assembly in the correct position

• Reconnect all electrical connections securely

• Reinstall and correctly clamp the hotend

• Reassemble the toolhead

• Confirm normal right-nozzle heating before beginning a long print

Follow the appropriate Bambu Lab X2D maintenance procedure when carrying out the replacement.

Troubleshooting Note

A right nozzle heating problem does not always mean the heating assembly itself has failed.

Similar symptoms may also result from:

• Loose connectors

• Damaged wiring

• Toolhead board faults

• Temperature-sensing problems

• Damaged hotend

• Physical damage around the nozzle

• Filament buildup around the heating area

The complete heating circuit should be diagnosed before replacing parts.

Usage Note

This product includes the X2D Right Auxiliary Hotend Heating Assembly only. The hotend, nozzle, silicone sock, hotend cooling fan, extruder, toolhead board, left heating assembly, and other toolhead components are not included unless separately specified.
