Extruder Gear
A small but critical component inside the 3D printer’s extruder mechanism responsible for gripping and pushing filament into the hotend. A worn or poorly designed gear leads to inconsistent extrusion and print failures.
Nickel Plating
A thin, corrosion-resistant coating applied to the surface of the gear to enhance durability, reduce friction, and improve wear resistance—especially important when printing with abrasive filaments like carbon fiber or metal-filled materials.
Hardened Steel
Steel that has undergone a heat treatment process to increase its hardness and resistance to deformation under high torque and repeated stress. This ensures the gear maintains its shape and tooth profile over thousands of print hours.
