Complete cold-end, including stepper motor. 5:1 geared extruder for high-powered filament extrusion. The Bondtech QR-M extruder gives you the markets highest performance, precision and reliability. Together with our proven and highly celebrated Dual-Drive technology you can expect problem free material feeding. This is the 2.85mm mirrored version and is a great upgrade for your 3D printer!
The Bondtech QR utilizes an Nema17 steppermotor with in integrated planatary gear reducer with 5:1 ratio together with precision cnc-machined hardened steel drive gears to give you a compact powerhouse for all your applications. 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. The housing parts are professionally SLS printed in nylon for maximum strength and precision.
Bondtech's unique Dual-Drive technology delivers uninterrupted material flow without fear of grinding or slipping in even the most demanding conditions. Bondtech users the world over 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.
The QR 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 2.85mm filaments. The filament path is fully guided throughout the extruder body and the housing maintains tight tolerances to the drive gears mitigating the chances of Filament Misfeed when the hotend experiences increased backpressure or highly flexible filaments are used.
The thumbscrew tensioner 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.
The QR feeds material with equal force in both directions so it is flexible when it comes to integrate it in your application.
The QR-M is compatible with:
