Overview
The Hardened Steel Extruder Gear Assembly is an internal component of the Extruder Unit. It comprises a driven gear and an active gear that work together to feed filament into the hotend.

Built with heavy-duty materials, the extruder gear assembly is designed for long-lasting performance. If abrasion or clogging occurs due to extended use, users can just replace the extruder gear assembly rather than the whole extruder unit.
