Extruder with high performance combined with a low weight, thanks to the Dual-Drive system.

Bondtech BMG is an extruder that presents a high performance combined with a low weight. These characteristics are due to the double gear drive, something innovative in the world of 3D printing. This system uses gears of hardened steel of great geometric pressure machined by CNC and a ratio of 3:1 to give a compact power, ideal for all types of materials. Whether you need to make high-resolution prints with small-diameter nozzles, large-volume prints with large nozzle diameters and high-speed retractions, this dual-gear system provides the necessary thrust and precision.

Bondtech BMG continues with the development of compact and powerful extruders, initiated by E3D-Online with the Titan Extruder and the Titan Aero. The Titan Aero revolutionized the world of 3D printing by offering a very small extruder compared to Greg Wade, with an improved gear ratio (3:1), transparent front cover and tight tolerances between the feed gear and the body of the extruder to be able to use flexible materials without problems. The BMG has almost all these advantages and the older has the Dual-Drive system to become the ultimate multi-material extruder.

Here are the most important aspects of the Bondtech BMG extruder:

Bondtech Dual-Drive

The Dual-Drive system offers the constant thrust of the filament without the fear of biting too much or skidding, even in the most demanding conditions, such as long-lasting 3D prints with thousands of retractions, with great precision and without any degradation in the filament or in the piece.

Multi-material capacity

Bondtech BMG is capable of transferring all types of material with complete confidence, from slippery nylons and flexible filaments (TPU / TPE) to filaments of high mechanical strength that contain carbon fiber, very rigid and sometimes brittle. This extruder is designed for filaments of 1.75 mm, but Bondtech ensures that it is able to move filaments with diameters from 1.5 mm to 2 mm, which gives a high security when printing, regardless of the tolerances of the filament. . This large diameter deviation only occurs in low-quality filaments. The path of the filament to the HotEnd is completely guided along the extruder, since the gap between the Dual-Drive and the casing is adjusted to the maximum to mitigate the possibilities of feeding error when using flexible materials or the extrusion speed she's very tall.

Adjustable tension

The manual adjustment screw allows the user to set the pressure exerted between the two transmission gears of the filament. The user can choose the pressure according to their preferences and the material they want to use.

Quick changes

The Bondgech BMG has an easily accessible lever that simply presses it to release the tension between the gears and the filament. This causes the filament change to take place in a matter of seconds.

Multi-application design

This extruder can be used for both Direct or Bowden type extruder systems, giving users the flexibility for all types of 3D printers. In addition, the BMG extruder is designed to use the powerful HotEnds v6 from E3D-Online or other HotEnds that meet the Groove Mount standard. Mounting the E3D-Online HotEnd V6  in the Bondtech BMG extruder is very simple and only requires removing two screws and replacing them. Many users are using Bondtech BMG with the HotEnd Volcano of E3D-Onlilne, since the BMG achieves a constant, precise and fast power supply that allows the capacity of the HotEnd Volcano to be pushed to the limit.

Flexible mounting

The new Bondtech BMG extruder offers the possibility of being installed in the vast majority of 3D printers 3D FDM / FFF on the market thanks to the fact that there is a wide range of mounting brackets depending on the model of the 3D printer of each user, for example, Bondtech Creality CR-10, Bondtech Creality CR-10S, Bondtech Wanhao D6 or Bondtech Tevo Tornado. Like the Titan Aero extruder, Bondtech BMG presents a standard and an opposite version (Miror), which is very practical for double extruder systems. In addition, this extruder is designed to adapt perfectly to the typical Nema17 stepper motor with 5 mm shaft.

The assembly of the Bondtech BMG extruder to a 3D printer 3D FDM / FFF ensures the elimination of the problems of the typical conventional extruders: excessive weight on the X axis, difficulties to print flexible materials, medium-low speeds of printing and retraction, discontinuous flow , process of uncomfortable and slow filament change, etc.

For all those users who want to get the most out of their 3D printer and make incredible pieces with any material and very quickly, the Bondtech BMG extruder is one of your best options.

Because Bondtech BMG uses a 3:1 gear ratio, it is necessary to change the value of the extrusion steps and configure E-Step: 415 steps / mm.
