How Bondtech solved filament feeding on 3D printers

2015

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.

Original Dual Drive Technology

1st generation of world's leading extruder technology Bondtech brought to market.

No filament shred or slips

Print faster or build more in less time without fails or under-extrusion.

Leading reliability and performance

Counter rotating drive gears' grip allows to print faster without failing.

Top precision and full control

Extrusion is mastered to the tune of 2 micron feeding resolution.
