Features: 100% brand new and high quality 100% brand new and high quality The Bondtech extruder combines high performance and resolution with low weight. Together with our proven and highly celebrated Dual-Drive technology you can expect problem free material feeding. The works in both bowden and direct driven applications. Built-in fitting for the hotend and fits Nema17 stepper motors. The uses a 3: 1 internal production ratio along with precision cnc machined hardened steel drive gears to give you compact power for all your applications. If you need high resolution prints with. Small nozzles or high flow prints with large nozzles, the optimized gear ratio combined with our industry leading drive gears provides unmatched pushing power and ultra-fast retraction in a compact, lightweight package. Because it is made of metal, you don't need to use the V6 heatsink during short-range printing, which saves space and improves heat dissipation efficiency. The printing effect is better than that of plastic materials. The printing of high hardness materials such as carbon fiber is very good.
