Beschreibung
Zusammenfassung:	The piezo-elements (8) of the ink ejection nozzles of a piezo print head are activated individually by a control unit, to eject ink and to form a coated layer by successive application of several ink layers, each with a predetermined shape, according to the shape of the molding object. After forming a predetermined number of printed layers, the ink ejection nozzles of the piezo print head are cleaned with a frequency stimulated by at least 20 kHz, for generating ultrasonic waves to break up any deposits in the nozzles. An independent claim is included for a device for layered construction of molding object by three-dimensional inkjet printing method.
