Dual Drive Bowden Extruder 1.75mm TPU | Ender 3, CR10, MK8

Dual Drive Bowden Extruder — Precision Upgrade for Ender 3, CR10 & More

Take your 3D printing to the next level with this Cloned Btech-Style Dual Drive Bowden Extruder. Engineered for 1.75mm filament including flexible materials like TPU and TPE, this extruder upgrade delivers exceptional grip, consistent extrusion, and reliable performance across a wide range of print demands. Compatible with popular platforms including Ender 3, Ender 3 V2, CR10, E3D V6, and MK8 setups.

Why Upgrade to a Dual Drive Extruder?

Standard single-drive extruders often struggle with flexible filaments and high-speed printing. The dual drive design grips filament from both sides simultaneously, dramatically reducing slippage, improving retraction precision, and enabling you to print with soft or flexible materials that a standard extruder simply cannot handle reliably.

Key Features

• 3:1 Internal Gearing Ratio — Optimized for maximum torque in a compact, lightweight form factor
• CNC-Machined Hardened Steel Drive Gears — Precision-machined for durability and consistent filament grip
• Dual Drive Mechanism — Grips filament from both sides for superior control and reduced skipping
• 1.75mm Filament Compatibility — Works with PLA, ABS, PETG, TPU, TPE, and more
• Flexible Filament Ready — Handles TPU/TPE with ease, minimizing buckling and jamming
• High-Flow & High-Resolution Capable — Whether you're running small nozzles for fine detail or large nozzles for fast prints, the gearing ratio keeps up
• Lightning-Fast Retractions — Minimize stringing and oozing for cleaner, sharper prints
• Broad Compatibility — Fits Ender 3, Ender 3 V2, CR10, E3D V6, and MK8 hotend setups
• Compact & Lightweight — Won't weigh down your carriage or compromise print quality

Who Is This For?

This extruder upgrade is ideal for makers, hobbyists, and professionals who want to push the limits of their Ender 3 or CR10 printer. If you've ever experienced skipping, grinding, or failed flexible filament prints, swapping to a dual drive extruder is one of the highest-impact upgrades you can make.

Frequently Asked Questions

Q: Is this dual drive bowden extruder compatible with the Ender 3 V2?

A: Yes! This extruder is designed to be compatible with the Ender 3, Ender 3 V2, CR10, and other printers that use E3D V6 or MK8 hotend configurations. It is a direct upgrade replacement for the stock extruder on these popular platforms.

Q: Can this extruder handle flexible filaments like TPU and TPE?

A: Absolutely. The dual-sided drive gear mechanism grips flexible filaments from both sides, greatly reducing the buckling and jamming issues that commonly occur with single-drive extruders when using TPU, TPE, or other soft materials.

Q: What is the gearing ratio and why does it matter?

A: This extruder features a 3:1 internal gearing ratio, meaning it provides three times the mechanical advantage compared to a standard 1:1 direct drive setup. This translates into more torque for pushing filament, more precise retractions, and better overall extrusion control — especially for high-resolution or high-flow printing scenarios.

Q: Does this extruder work with 3mm filament?

A: No, this model is specifically designed for 1.75mm filament only. It is not compatible with 2.85mm or 3mm filament systems.
