Fused filament fabrication system with interchangeable print heads and filament

Abstract

Provided herein is a fused filament fabrication system having a number of print heads, a print head mount, and a gantry. So-called filament modules can be connected to the print heads. The print heads can be docked into a special print head dock or into one of the filament docks if a filament module is arranged in between. Filament feeders feed filament to the filament modules. A control system controls the gantry to select one print head from the number of print heads. The selected print head can be used for a printing job having the current filament attached, or it can be moved to another filament dock to first pickup a different filament. The selected print head can also be parked to select another print head. Multiple print heads can thus be combined with multiple filaments without user intervention.
