Beschreibung
Zusammenfassung:	The present invention relates to a printing device (1), preferably a 3D printer (1), comprising at least one printing nozzle (3) which is designed to eject a flowable material through at least one ejection opening (32) in the direction of a work surface (11) which is preferably horizontal. The printing device (1) is characterized in that the printing nozzle (3) has a stationary printing nozzle frame (30) and a printing nozzle head (31) with the ejection opening (32), which printing nozzle head (31) can be moved, preferably in the vertical direction (Z), relative to the printing nozzle frame (30), wherein the printing nozzle (3) is designed to move the printing nozzle head (31) relative to the printing nozzle frame (30), preferably in the vertical direction (Z), between an open position, in which a flow of the flowable material through the ejection opening (32) is permitted, and a closed position, in which a flow of the flowable material through the ejection opening (32) is not permitted, by means of a drive, preferably by means of a piezoelectric or pneumatic drive, wherein the ejection opening (32) of the printing nozzle head (31) is spaced apart further from the work surface (11) in the closed position than in the open position.
