Bambu Filament Buffer — H2S (SA010)

Official Replacement Assembly • Smooth Filament Feeding • Genuine Bambu Lab Part

Overview

The Bambu Filament Buffer (SA010) is the official replacement filament buffer for the Bambu Lab H2S. Installed between the AMS and the printer, it regulates filament movement by maintaining consistent tension and providing a controlled filament reserve. This allows the AMS and extruder to operate independently, resulting in smoother feeding, more reliable material changes, and reduced strain on the filament path.

Whether you're replacing a damaged unit or keeping a spare on hand, the genuine Bambu Lab Filament Buffer helps ensure dependable multi-material printing and consistent extrusion performance.
