1. A method for printing three-dimensional objects, layer by layer, the method comprising:

  • automatically generating a pre-designed scanning plan for printing a layer of a three dimensional object in two or more scanning passes by a relative movement in a scanning direction of a printing head and a printing tray, where the pre-designed scanning plan includes a start position, and each of the scanning passes is assigned a respective length determined based on image data parameters of the layer;

    performing, by a computing device, an optimization scheme to determine the start position of the pre-designed scanning plan so as to minimize an accumulated length of all lengths of the scanning passes; and

    selectively depositing material from the printing head according to the pre-designed scanning plan to form the layer.
