Extruder Gear The extruder gear is a key mechanical component of the extruder system in a 3D printer. It is responsible for gripping and driving the filament through the extruder and into the hot end. Typically made of durable materials like hardened steel or brass, the gear features sharp teeth that ensure a secure grip on the filament, even during high-speed printing. Over time, extruder gears can wear out, especially when using abrasive filaments, leading to inconsistent feeding or slipping. Regular inspection and replacement of the extruder gear are important for maintaining reliable extrusion. Upgraded extruder gears, such as dual-drive systems, can improve performance for demanding applications. |
