Official Replacement Feeder • Automatic Filament Loading • Genuine Bambu Lab Part

Overview

The Bambu AMS 2 Pro Feeder Unit (SAA035) is the official replacement feeder assembly for the Bambu Lab AMS 2 Pro. Each AMS 2 Pro contains four independent feeder units, each with its own motor, drive gears, and filament sensor to actively feed filament into the printer or rewind it back onto the spool during automatic material changes. Ceramic-reinforced anti-wear bushings help reduce wear from continuous filament movement, even when printing abrasive materials.
