Focus on material and tooth design. Hardened steel gears resist wear from abrasive filaments like carbon fiber or glow-in-the-dark blends, while brass wears faster but grips softer filament gently. Dual-drive gears bite from both sides for stronger, more reliable feeding than a single gear against a bearing. Match the bore diameter to your motor shaft, usually 5mm, and confirm the tooth pitch works with your extruder body so the gears mesh cleanly without backlash. These guides fit anyone fixing under-extrusion, grinding, or filament slipping, and anyone converting a stock single-drive extruder to dual-drive. Abrasive-filament users should prioritize hardened steel, while general PLA and PETG printers can run standard sets. A practical tip: replace both gears together in a dual-drive system so wear stays even, and clean filament dust from the teeth regularly, since packed debris reduces grip and causes skipped steps.
