Affordable DualDrive performance for Ultimaker printers

Bondtech now brings you DualDrive performance to your Ultimaker in a easy to install and affordable package. It provides high feeding capacity together with our proven and highly celebrated Dual-Drive technology for maximum performance without grinding and slipping.
The photo below shows the performance using the same identical settings, the factory extruder underextrudes but Bondtech DDG extruder feeds the material without any underextrusion or griding of the material.

Our new design reuses the factory stepper and parts from the Ultimaker 2+ (Ultimaker3) feeders in order to keep the costs down.

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

MaraudiOur unique Dual-Drive technology delivers uninterrupted material flow without fear of grinding or slipping in even the most demanding conditions. Bondtech users worldwide 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 new DDG 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 2.85/3.0 mm filaments. The filament path is fully guided from the DriveGears and up and the extruder body and the housing maintains tight tolerances to the drive gears mitigating the chances of Filament missfeed when the hotend experiences increased back pressure or highly flexible filaments are used.

Adjustable tension

The adjuster screw 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.


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 insert the new material.
