1. A method of configuring an additive manufacturing system, comprising:
dividing an initial model into a plurality of segments, the initial model defining a geometry of an object;
calculating, for each of the plurality of segments, a stress value using a cross-sectional area of the segment and a calculated weight of material residing atop the segment;
predicting a deformation of each of the segments according to the associated stress value as a result of a sintering process following deposition of all of the segments;
calculating, for each of the plurality of segments, a modified geometry of the segment as a function of the predicted deformation;
defining a printed geometry of the object from the collective of modified geometries of each of the segments; and
printing the object according to the printed geometry.
