BMG Extruder

BMG4-frilagdBMG-E3dV6-webb

Maximum performance, minimum size

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. The below chart shows the pushing force of different materials and the weight of our extruders compared to our competitors.
All testing were done with this test setup.

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

MaraudiOur 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

fully-guidedOur 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   1.5 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 back pressure or highly flexible filaments are used.

 

Adjustable tension

BMG-PretensionThe 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, 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.
