Bondtech benefits

Multi-material capability

fully-guidedOur new BMG extruder feeds all material with high reliability, from slippery nylons and soft TPU/TPE filaments to highly rigid and sometimes brittle carbon-filled high-strength materials. The extruder is designed for 1.75 mm filaments, but has been tested to ensure performance of filament from 1.5 mm up to 2.0 mm allowing for high reliability regardless of the tolerance of the filament used. The filament path is fully guided throughout the extruder body and the housing maintains tight tolerances to the drive gears mitigating the chances of Filament misfeed when the hotend experiences increased back pressure or highly flexible filaments are used.

Adjustable tension

BMG-PretensionThe thumbscrew tensioner allows the user to fine-tune the pressure exerted by the drive gears onto the filament.  This gives you the power to adjust according to your preferences and to optimize for the type of material you are using.
