The drive extruder utilizes an internal gearing ratio of 3:1 together with precision cnc-machined hardened steel drive gears to give you a compact powerhouse for all your applications.Whether you require high resolution prints with small nozzles or high-flow prints with big nozzles the optimized gearing ratio combined with our industry leading drive gears provides unparalleled pushing and fast retractions in a lightweight and compact package.Because it is made of metal, it does not need to use V6 heatsink during short-range printing, which saves space and improves heat dissipation efficiency. The printing effect is that of plastic materials. Printing high-hardness materials such as carbon fiber is very good.Item Type: ExtruderModel Number: Bowden Extruderadvantage: high qualitySuitable for: FOR Wanhao D9 CR10 3 Anet E10color:BlackMaterial:MetalPackage Contents:1 x All Metal Drive Extruder(right)Only the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
