Dual-Drive technology delivers uninterrupted material flow without fear of grinding or slipping in even the most demanding conditions
Feeds all material with tested high reliability, from slippery nylons and soft TPU/TPE filaments to highly rigid and sometimes brittle carbon-filled high-strength materials.
The thumbscrew tensioner allows the user to fine-tune the pressure exerted by the drive gears onto the filament.
Quick-Release lever releases tension for material changes in a snap.
Features an integrated hotend retention method compatible with the E3D-V6 hotends or others using the Groove Mount standard.
The Bondtech QR Universal 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 universal solution fits both bowden and direct driven applications.
