Zusammenfassung:	Methods and systems (100) of printing a 3D object (101) comprising: depositing material, layer by layer, via printing heads (72) comprising one or more nozzle arrays; and activating each of said printing heads (72) to dispense a building material (50) at least once within a specified period of time during printing. L'invention concerne des procédés et des systèmes (100) d'impression d'un objet 3D (101) comprenant : le dépôt d'un matériau, couche par couche, par l'intermédiaire de têtes d'impression (72) comprenant un ou plusieurs réseaux de buses ; et l'activation de chacune desdites têtes d'impression (72) pour distribuer un matériau de construction (50) au moins une fois dans une période de temps spécifiée pendant l'impression.
