A method of additive manufacturing of a three-dimensional object (12). The method comprises sequentially forming a plurality of layers each patterned according to the shape of a cross section of the object (12). In some embodiments, the formation of at least one of the layers comprises performing a raster scan to dispense at least a first building material composition (24), and a vector scan to dispense at least a second building material composition (24). The vector scan is optionally along a path selected to form at least one structure selected from the group consisting of (i) an elongated structure, (ii) a boundary structure at least partially surrounding an area filled with the first building material, and (iii) an inter-layer connecting structure. |
