Harness Bondtech technology in your custom-built extruder

Bondtech revolutionized the 3D printer extruder market when they released the QR extruder and it's dual-drive hardened steel hobbed gears. An extruder that can grip filament better than ever before thanks for hobbed gears on both sides also improves torque for increased reliability. Having this extruder gears manufactured from hardened steel also guarantees a long life of precision extrusion even with abrasive materials like NylonX.
