A method of printing a three-dimensional object, comprises: for each of a plurality of arrays of nozzles, activating a subset of nozzles of the array to dispense a respective building material from the subset, so as to form an interleaved scan pattern of dispensed materials. The method comprises hardening the interleaved scan pattern, and repeating the activating and the hardening to form a stack of hardened interleaved scan patterns.

Method and system for reducing waviness in three-dimensional printing

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.
