BMG-M Extruder

The Bondtech BMG-M extruder combines high performance and resolution with low weight. Together with Bondtech's proven and highly celebrated Dual-Drive technology, you can expect problem-free material feeding.

Designed for Mosquito®
This extruder is optimized for the Mosquito® / Mosquito® Magnum hotends with an integrated torque lock system to make the interface very strong. It also makes nozzle changes a breeze.

Made with PA12 by SLS
The housing parts are professionally SLS printed in nylon for maximum strength and precision.

Note: This Bondtech BMG-M extruder only supports 1.75 mm size filament.

What’s in the box
The following elements are supplied with the BMG-M:

• BMG-M Assembly with Drive Gears and Push-fit
• Thumbscrew Assembly
• Brass Motor Gear with Set Screw

Nickel Coated Hardened Steel Drive Gears
The Bondtech BMG-M utilizes an internal gearing ratio of 3:1 together with precision cnc-machined Nickel Coated 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 Bondtech's industry-leading drive gears, provides unparalleled pushing power and lightning fast retractions in a lightweight and compact package.

Bondtech Dual-Drive
Bondtech's unique Dual-Drive technology delivers uninterrupted material flow without fear of grinding or slipping in even the most demanding conditions. Bondtech's users all over the world will attest that even in prints with thousands of retractions, Bondtech's extruders perform flawlessly, with unmatched precision, and zero damage or degradation to the filament.

Multi-Material capability
Bondtech's BMG-M extruder feeds all material 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 the performance of filament from 1.5 mm up to 2.0 mm allowing for high reliability regardless of the tolerance of the filament 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.

Adjustable tension
The thumbscrew tensioner allows the user to fine-tune the pressure exerted by the drive gears onto the filament. This gives you the power to adjust, according to your preferences, and to optimize for the type of material you are using.

Quick-Release
To be able to do material changes in a snap, simply activate the Quick-Release lever to release the tension and pull the material to be changed out of the extruder. While keeping the lever-activated, insert the new material.

Optimized design
Mounting your hotend is simple, secure, and wobble-free by means of just two bolts.
