E3D Titan Extruder Hardened Steel Hobb Gear Upgrade

A hardened steel hobb offers significantly superior abrasion resistance compared to standard stainless steel. This is crucial when printing with abrasive filaments like carbon fiber, glass-filled, or metal-filled materials, preventing premature wear, maintaining consistent filament grip, and ensuring long-term extrusion accuracy for higher quality prints.

Yes, this hardened steel hobb is designed as a direct drop-in replacement for all E3D Titan extruders. It comes pre-fitted into the Delrin large gear, ensuring easy and straightforward installation without requiring any modifications to your existing extruder setup.

The hardened steel hobb's resistance to wear ensures that its teeth maintain their sharp profile, consistently gripping the filament with precise force. This prevents slippage and inconsistent extrusion, which are common issues with worn hobbs when using abrasive materials, leading to more reliable and higher-quality print output.

The large gear into which the hardened steel hobb is pre-fitted is made from Delrin (acetal resin). Delrin is chosen for its excellent mechanical properties, including low friction, high stiffness, and dimensional stability, which contribute to the smooth and precise operation of the extruder drive system.
