Greater tractive force.

The double drive gear traction system of the new extruder provides perfect grip of the filament: the two gear wheels apply pressure and pull it smoothly through to the hot-end. Designed and developed from scratch by the BQ hardware and mechanical design team, it is one of the few extruders on the market that allow the pressure exerted on the filament to be modified according to the material used. With the risk of obstruction minimised, a greater variety of filaments can be used, such as PLA, bronze, wood, copper and even flexible materials such as FilaFlex.

All the necessary material for impeccable printing results.
