This Bondtech DDX Extruder is suitable for 3D printers of the Creality Ender and CR-10(S). This copy is a very powerful dual drive extruder based on the BMG Bondtech Mini Geared. It gives you all kinds of options to, for example, print with different materials, use wider nozzles and create super detailed 3D prints. The housing provides effective cooling of the hot end. Thanks to the transmission ratio of 3:1 you can achieve high resolution prints with narrow nozzles or high flow prints with larger nozzles. The kit replaces the original Bowden extruder of your 3D printer. Tools are required to assemble the kit (Allen and screwdrivers).
