We have both left and right handed versions in stock so you can even use them on the BCN3D Sigma. Any dual extrusion setup can thus benefit from the Bondtech.

Changing  filament is a breeze with the new lever system while the spring-loaded secondary drive gear adapts to filament variations and optimal pressure can be adjusted to match your preferences.

The gear system is custom made for the QR and every gear is harded to ensure long and reliable service, even when using the most abrasive of filaments.

Super sharp drive gear teeth’s grips the filament from both sides that gives very high available feeding force to ensure uninterrupted material flow to avoid under extrusions. Filament grinding and slippage is now a thing of the past.
