Abstract: A method of three-dimensional fabrication of an object is disclosed. The method comprises: forming a plurality of layers in a configured pattern corresponding to the shape of the three-dimensional object, at least one layer of the plurality of layers being formed at a predetermined and different thickness selected so as to compensate for post-formation shrinkage of the layer along a vertical direction. In various exemplary embodiments of the invention spread of building material of one or more layers is diluted at least locally such as to maintain a predetermined thickness and a predetermined planar resolution for the layer.

Abstract: A method for preventing detachment of a three-dimensional object from a printing tray of a printing apparatus is disclosed. The method includes printing a carpet of building material below and around the base of a three-dimensional object to be printed; and printing said three-dimensional object. The portions of the carpet that protrude out of the boundaries of the base of the three-dimensional object are coated with one or more layers of support material to help keep the carpet flexible and adhesive in texture.

Abstract: A method for printing a three-dimensional objet, layer by layer is provided. The method involves printing an inner region of a layer of the three-dimensional object and an outer circumference region. The inner region includes a white outline area and the outer circumference region surrounds the white outline area. The outer circumference region that forms an apparent colored surface includes colored voxels formed by depositing a transparent building material and at least one color additive material and is printed such that the resolution of the color additive is higher than the building material resolution.
