Bondtech BMG extruder

The Bondtech BMG utilizes an internal gearing ratio of 3:1, along with precision CNC-machined hardened steel drive gears, to create a compact powerhouse for all your applications. Whether you require high-resolution prints with small nozzles or high-flow prints with larger 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.

Bondtech Dual-Drive technology delivers uninterrupted material flow without fear of grinding or slipping, even in the most demanding conditions. Bondtech users worldwide attest that even in prints with thousands of retracts, our extruders perform flawlessly, with unmatched precision and zero damage or degradation to the filament.

Our BMG extruder feeds all materials with high reliability, from slippery nylons and soft TPU/TPE filaments to highly rigid and sometimes brittle carbon-filled high-strength materials. The extruder is designed for 1.75 mm filaments but has been tested to ensure performance with filaments ranging from 1.5 mm to 2.0 mm, allowing for high reliability regardless of the filament tolerance used. The filament path is fully guided throughout the extruder body, and the housing maintains tight tolerances to the drive gears, mitigating the chances of filament misfeed when the hotend experiences increased backpressure or highly flexible filaments are used.

The thumbscrew tensioner allows the user to fine-tune the pressure exerted by the drive gears onto the filament, giving you the power to adjust according to your preferences and optimize for the type of material you are using. For quick material changes, simply activate the Quick-Release lever to release the tension and pull the material to be changed out of the extruder. Keep it activated and insert the new material.
