Swedish company, Bondtech has released the lightweight BMG Extruder that the company say will save users both time and money.
The BMG is a lightweight extruder with high feeding capacity and strong force to weight ratio. Bondtech believes the BMG has the best force to weight ratio on the market and will result in both high accuracy and speed of prints.
Performance is achieved via Bondtech’s Dual-Drive technology which prevents grinding and slipping of filaments. Bondtech has used this technology before in their QR extruder. However, CEO Martin Bondéus wanted to improve the company’s offerings even further with a lightweight option.
Lighter extruders enable printers to stop and start at less force, this prevents wobble when printing, improving reliability. The BMG is engineered for use in a Bowden or direct setup.
While the Bondtech QR extruder provides reliable force, it is much heavier than the BMG.
The BMG has a gearing ratio of 3:1 ensuring high torque and the CNC machined steel drive gears maintain good reliability.
The BMG extruder, “feeds all material with high reliability” with a thumbscrew tensioner that allows the user to control the pressure exerted by the drive gears on to the filament. This feature means the extruder can be optimized for specific materials. Bondtech believe the extruder can handle both flexible filaments like nylons, and stiff carbon-filled materials with ease.
In the materials market, 3D Printing Industry recently reported that materials conglomerate Dupont has released its first plastic filaments. It would be interesting to see how these high performance materials would be handled by the BMG extruder.
