Beschreibung
Zusammenfassung:	A system for additive manufacturing (AM), comprising a build plate for positioning an object to be created, and at least one printhead assembly for fused deposition modeling that comprises connecting means for connecting the printhead assembly to a positioning system, heat exchanging means and a feedstock liquefying unit for liquefying AM feedstock. The feedstock liquefying unit comprises a nozzle for depositing liquefied AM feedstock onto at least one of the build plate and the object to be created. The system further comprises feedstock supply means arranged for feeding the feedstock into the feedstock liquefying unit.The system further comprises a positioning system associated with at least one of the printhead assembly and the build plate, arranged for relative spatial positioning of the printhead assembly and the build plate. The system further comprises a feedstock liquefying unit storage, comprising holding means for accommodating at least one feedstock liquefying unit, and a controller arranged for controlling the positioning system for disposing the feedstock liquefying unit in a feedstock liquefying unit storage, and for controlling the positioning system for acquiring a replacement feedstock liquefying unit from the feedstock liquefying unit storage. The heat exchanging means is configured and arranged to establish a releasable clamping connection with the feedstock liquefying unit to accommodate the feedstock liquefying unit in the printhead assembly.
