Bondtech's Dual Drive gear technology, a pivotal innovation introduced with the V2 feeder, revolutionized 3D printing by ensuring reliability and precision.
With two counter-rotating drive gears, issues like filament shredding and slipping were eliminated, enabling precise material feeding, superior prints, and enhanced speed, adding undeniable value to any printer.
Bondtech's dual drive technology transformed 3D printing, making this extruder a pioneer of the Makers’ revolution.
Best in class to handle flexibles
Print flexible materials faster with much less print fails or under-extrusion.
Very compact toolheads
Shortening the filament path creates the most compact print head setups.
Versatile form factor
More ways to install allows wider 3D printer compatibility and application.
Increased build speed
An unexpected result is the increase of Volumetric Capacity.

Wanted to let you know just how powerful your drive for my Prusa Mini is. The filament in the roll was not wound properly and tangles up. Your direct drive actually pulls the roll of filament up and out of the base. This has happened 3 times.
Thought you might like to know how "BAD ASS" your drive is. Printing PLA and just realized adjustment is still set for Polypropylene I was originally printing so it isn't even set to grip tighter. Very Impressive!
