Abstract
An extrusion head for additive manufacturing of a product includes a material feed unit for feeding an extrusion material, preferably in filament form, a separating device for the extrusion material, and optionally a displacement unit with at least two liquefying assemblies. The extrusion material can be introduced into a first liquefying assembly, and the upper end of the extrusion material separated by the separating device can be introduced into a second liquefying assembly. A cooling device is provided for cooling the displacement unit and/or the separating device.
