1. A method for building a three-dimensional model with an extrusion-based digital manufacturing system, the method comprising generating a contour tool path that defines an interior region of a layer of the three-dimensional model, wherein the contour tool path comprises a start point, a stop point, and a step-over arrangement between the start point and the stop point, wherein the step-over arrangement is oriented at a non-right angle, wherein at least one of the start point and the stop point is located within the interior region of the layer, and wherein the step-over arrangement reduces surface porosity for the three-dimensional model.
