Mellow Bowden NF Nitrogen-Based Chain RN-DDG Extruder Dual Drive Gear For 3D Printer Ender 3 Blv Mgn Cube Flyingbear Ghost 5

1.The transparent material allows the user to better observe whether the extruder is properly extruded. For example, the tpu is prone to problems during the extrusion process.

2.This plastic RN-DDG is made of petg mixed nylon, which makes it less susceptible to damage while maintaining transparency.

3.Our gears are produced by Japanese high-precision cnc machine tools. After different production processes, the final quenching transformation will harden the steel, and the surface is Nano coating, so that the gears are more beautiful while maintaining the hardness. High-precision machining also helps each tooth distribution. Uniformity makes the filament more stable and precise during the extrusion process, reducing filament breakage and nozzle clogging, creating a sharp difference from inexpensive gears.

The RN-DDG 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 power and lightning fast retractions in a lightweight and compact package.
