Methods of printing a 3D object comprising depositing a building material, layer by layer, via printing heads comprising one or more nozzle arrays; and activating each of said printing heads to dispense a building material at least once within a specified period of time during printing to form a portion of said bulk region according to data provided by a CAD file, and activating said printing heads to deposit the building material to form another portion of the bulk region without relating to said data.

Method for enhancing the lifetime of printing heads used in additive manufacturing

A method of additive manufacturing of a three-dimensional object, comprises: dispensing from a first array of nozzles a modeling material formulation containing a polyimide precursor to form a layer in a configured pattern corresponding to a shape of a slice of the object; applying to the layer ultraviolet radiation and infrared radiation from two different radiation sources; and repeating the dispensing and the application of radiation to form a plurality of layers in configured patterns corresponding to shapes of other slices of the object. Optionally, an additional modeling material formulation or a support material formulation is dispensed from a second array of nozzles.
