1. A method for forming at least a portion of a three-dimensional object on a layer-by-layer basis from a medium solidifiable upon selective exposure to synergistic stimulation according to data representations corresponding to said three-dimensional object, comprising the steps of:

  • a) applying a layer of flowable material capable of solidification upon exposure to synergistic stimulation onto any previously solidified layer of the three-dimensional object;

    b) selectively exposing said layer to synergistic stimulation to form a layer of said three-dimensional object;

    c) repeating steps a) and b) for subsequent layers until at least the portion of said three-dimensional object is formed and wherein the steps of exposing said layers further comprise exposing at least a portion of at least one layer with interrupted, non-overlapping points of exposure to synergistic stimulation such that said at least portion is solidified as substantially discrete and non-overlapping regions.
