2016
Streamlining the filament loading process, formerly slow, inconsistent and cumbersome, was our priority.
With Quick Release featuring an intuitive thumb-screw and flexible hinge, loading and unloading filament became effortless, offering tool-free operation and maintaining consistent pre-tension settings for seamless user experience and reliable parts production.
Bondtech’s Quick Release solution quickly became a standard in the industry, revolutionizing 3D printing and making it easier for all.
Intuitive and easy to use
Release filament pre-tension using your thumb and index fingers.
Simple load and unload
Drive gears are set far apart for easy filament load and unload.
Tweak filament pre-tension
Turn the thumbscrew to fine tune the distance between drive gears.
A better and affordable way
Simple, easy and cheap while being a better solution for 3D printer users.
