Bambu Lab A1 – AMS Guard – cover for protecting filament inlet

Bambu Lab A1 – AMS Guard – cover for protecting filament inlet - Complete set of 4 pieces

The original Bambu Lab A1 AMS Guard is a small but important part that protects the filament inlet from the AMS Lite to the Bambu Lab A1 printer. It minimizes the risk of dust and debris entering the feeding mechanism and helps prevent filament feeding issues.

What the AMS Guard is used for

• Protects the filament inlet opening between the AMS Lite and the A1 printer.
• Limits the ingress of dust, filament fragments, and other impurities into the filament path.
• Reduces the risk of jamming or poor feeding of the material.
• Provides a clean and safer filament routing near the printer.

This part is ideal as a replacement cover in case of damage or loss of the original part supplied with the printer.

Main benefits

• Original Bambu Lab part – guaranteed compatibility with the Bambu Lab A1 printer and AMS Lite.
• Precise fit – the cover is designed to fit exactly in the designated place without the need for modifications.
• Filament path protection – helps maintain a clean and smooth filament path from the AMS Lite to the extruder.
• Quick replacement – installation is simple, suitable even for beginner users.

Installation

Installing the AMS Guard is very simple:

1. Turn off the printer and, if necessary, disconnect the AMS Lite.
2. Check the filament inlet area from the AMS to the A1 and, if necessary, remove any filament residue.
3. Place the AMS Guard in the appropriate position according to the shape of the part.
4. Make sure that the cover holds firmly and does not interfere with the filament path.

In case of doubt, we recommend consulting the official Bambu Lab documentation or the wiki for the A1 printer and AMS Lite.
