Extrudervorrichtung (1) zur Extrusion von einem Strang (ST) von Baustoff (BS) zum 3D-Druck von einem Bauwerksteil (BWT), wobei die Extrudervorrichtung (1) aufweist: eine Extruderdüse (5), wobei die Extruderdüse (5) eine Austrittsöffnung (2) zum Austritt des Strangs (ST) von Baustoff (BS) aus der Extrudervorrichtung (1) heraus aufweist; und mindestens ein Innenelement (30a, 30b), wobei das mindestens eine Innenelement (30a, 30b) zur Anordnung innerhalb der Extruderdüse (5) zur Definierung eines Innenrands (35l) eines Strömungsquerschnitts (35) von Baustoff (BS) innerhalb der Extruderdüse (5) zur Vorgabe eines Innenrands (4I) eines Strangquerschnitts (4) des ausgetretenen Strangs (ST) von Baustoff (BS) ausgebildet ist.
(EN)
The invention relates to an extruder device (1) for extruding a section (ST) of construction material (BS) for 3D printing a construction part (BWT), wherein the extruder device (1) has: an extruder nozzle (5), said extruder nozzle (5) having an outlet opening (2) for discharging the section (ST) of construction material (BS) out of the extruder device (1); and at least one inner element (30a, 30b), wherein the at least one inner element (30a, 30b) is designed to be arranged within the extruder nozzle (5) in order to define an inner edge (35I) of a flow cross-section (35) of construction material (BS) within the extruder nozzle (5) so as to specify an inner edge (4I) of a cross-section (4) of the construction material (BS) section (ST) which has exited the extruder device.
