The surface is treated with hard nickel plating, which is wear-resistant and has the effect of rust prevention. The printing effect is better. The hardened steel extruder gear component is compatible with the factory models X1 series and P1P, consisting of transmission gears and driving gears, and can send consumables to the hot end. The handle is made of aluminum alloy processing, and the official handle is made of plastic material. However, if it is worn and replaced after long-term use, it is easy to damage. Upgrading to a metal handle can provide longer working hours and facilitate the replacement of extruded gears. The metal material is more durable and increases its service life. Hardened steel gears enable the extruder to print engineering consumables such as carbon fiber nylon and glass fiber nylon.
