The Dual Drive BMG Extruder is a high-performance upgrade for 3D printers, designed to deliver precise filament feeding, enhanced grip, and superior print quality. This dual gear drive extruder eliminates common issues such as filament slipping, inconsistent extrusion, and under-extrusion, ensuring smooth and reliable 3D printing results.

Engineered with BondTech-compatible dual-drive technology, both gears grip the filament from both sides, providing a consistent extrusion force even with flexible or abrasive materials like TPU, PETG, ABS, and PLA. The extruder features an adjustable tension mechanism that allows users to fine-tune pressure for different filament types, improving feeding precision and reducing nozzle clogs.

Built from high-strength aluminum alloy, the BMG extruder offers exceptional durability compared to stock plastic extruders found in many entry-level printers. It is ideal for E3D-style direct drive hot ends and supports 1.75mm filament with PTFE tube compatibility (2x4mm). This makes it a perfect upgrade for printers like Ender 3, CR-10, Anycubic, Artillery, and Prusa i3 clones.

The compact and lightweight design reduces extruder inertia, improving retraction speed and print accuracy—especially important for direct drive 3D printers. The kit comes pre-assembled and includes a mounting bracket for NEMA17 stepper motors, making installation quick and straightforward.
