## Overview

The Bondtech Genuine BMG Extruder (EXT-BMG) is a high-performance, lightweight 3D printer extruder featuring a 3:1 internal gearing ratio and precision nickel-coated hardened steel drive gears. Designed for both Bowden and direct drive setups, it supports a wide range of filament types and diameters (1.5mm to 2.0mm) with adjustable tension control and a quick-release mechanism for fast filament changes. Trusted worldwide for its reliability and precision, the BMG extruder delivers consistent, high-resolution prints with minimal maintenance.

## Description

Bondtech Mini Geared Features The Bondtech BMG 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 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 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 back-pressure 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, keep it activated and i

Review: Great build quality - Works as it should. Excellent build quality. You do not need a bowden adapter for it, as you just run it in reverse for bowden setup.
Review: Excellent extruder, but expensive - The real BMG is beautifully high quality and works great. I am using it in a direct drive setup on my ender 5 with a micro swiss clone hotend. I bought it months to replace a bmg clone that wasn't working right, where I didn't want to modify my print head config. Turns out something else in the setup was the problem, and the clone is still fine. I use the clone to this day on an ender 3 printer and I must say the clones are a much better value especially on cheap creality printers like what I have. The design is not identical (bondtech is tighter and more complex; clone takes shortcuts on geometry and internal parts) and the machining quality on the gears and tolerances on other parts are so much sloppier on the clone. However the print results are exactly the same using a part that is a fraction of the price (15 bucks). I have noticed no difference with respect to extrusion quality or use with flexible filaments between the two setups where the hotend configs are identical besides the extruders. maybe the real BMG will last longer, but I have hundreds of hours more print time on the clone and it holds up. I don't like praising the knockoff product so much, but given the enormous price gap on essentially matched performance, it would be nice if bondtech could offer something comparable for less $$$

### ⭐⭐⭐⭐⭐ Great product, some tweaking, but does the job nicely!
*by N***. on 12 March 2024*

Have to adjust the Acceleration of the Extruder otherwise motor might skip on retracts because of the 3:1 gear ratio. So far handles fast and slow through a small bowden on my Ender 3 really well. Getting nice and even results. My only complaint was that the gear was grinding on some loose plastic that wasn't trimmed off it seemed, once I trimmed the plastic myself with a razor blade, gear worked smoothly. Little overpriced, but it is what it claims to be.
