Pre-tension Lever

How we redefined filament management again

2019

This groundbreaking patented solution builds upon the success of the Quick Release design and addresses user feedback to provide enhanced usability and control.

The cam-shaft mechanism allows for effortless filament loading and unloading while offering multiple pre-defined pre-tension settings for optimal results. Say goodbye to manual adjustments and enjoy simplified, precise, and repeatable filament management with this simple user interface,

Bondtech unlocked a new level of convenience, control, and reliability to 3D printer users worldwide.

Easier than ever before

Just flick a lever to set the optimal available filament pre-tension.

Uniform and repeatable

Get the same results when using the same materials and settings.

For every type of filament

0+5 pre-settings fit all types of filaments from soft to hard and abrasive.

A patented true innovation

An evolutionary technology you can only use with Bondtech eXtruders.
