Bondtech now brings you the best and lightest performing extruder on the market that combines low weight with high feeding capacity together with our proven and highly celebrated Dual-Drive technology for maximum performance without grinding and slipping.
For 1.75 mm size filament only.


The Bondtech BMG utilizes an internal gearing ratio of 3:1 together with precision cnc-machined 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 our industry leading drive gears provides unparalleled pushing power and lightning fast retractions in a lightweight and compact package.

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

Multi-material capability
Our new BMG 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 performance of filament from 1.5mm up to 2.0mm 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.

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, keep it activated and insert the new material.

Multi-application design
This new extruder can be used in a Bowden or direct setups and gives you the flexibility to choose what works best for your application. In addition it features an integrated hotend retention method compatible with the E3D-V6 hotends or others using the GrooveMount standard. Mounting your hotend is simple, secure, and wobble free by means of just two bolts.

Flexible mounting options
We have designed a standard mounting bracket, both in CNC and as a 3D printable part that you can download from our stl-archive for free. Our standard mount is CNC-machined in 3 mm aluminum for maximum stability. Please see below for available mounts.

The extruder can use any Nema17 motor with a standard 5 mm shaft. For suitable motors please select one of the below or use your own motor.

This extruder is sold without motor!
Weight without motor: 75g

Great extruder

Easy to setup and swap into my anycubic predator

Simple, Reliable, Dual-Gear Extruder

The OEM Bondtech BMG comes at a premium to the copycats, but it's well worth it. After creating an adapter plate for the BMG + e3d V6 I was able to install it without issue. I immediately saw an improvement in filament movement and extrusion consistency. No more grinding, more consistent flow, and it even handles flexible and soft filaments without issue. I bought the left-hand version to replace the lower quality copycat that came stock in my Anycubic 4Max Pro 2.0. If you're starting from scratch or upgrading most other machines I'd choose the right-hand (standard) version instead.

Haven't been able to use it yet. I may have damaged the main gear. The extruder binds up when tightened to the stepper motor. I ordered a new gear from u. Waiting for it now.

Nice quality parts.

Bought it to use as parts for a voron afterburner. Much nicer parts then I was getting from the China copies.

Almost perfect.

Very good extruder, one thing I think it's missing though is the Bowden Groove Collar. That's actually sort of required even for direct drive installations to prevent the bowden tube linkage between the hotend and the extruder from buckling. Other than that, I'm really happy with the overall quality and performance.
