Claim One:
1. A method for data driven shrinkage compensation to improve fabrication of objects using an additive manufacturing process, the method comprising: subdividing, by a polygon subdivider, polygons in a three-dimensional file modeling an object into facets; calculating, by an axis dimension calculator, dimensions of the object modeled in the three-dimensional file from an x-directional strand disposed between two facets of a first predetermined facet pair, a y-directional strand disposed between two facets of second predetermined facet pair, and a z-directional strand disposed between two facets of a third predetermined facet pair, the object being formed from at least some of the polygons; predicting, by a dimension change predictor, dimensional changes in the x-directional strand, the y-directional strand, and the z-directional strand as a result of the fabrication of the object using the additive manufacturing process based on a shape shrinkage model; and correcting, by a dimension change compensator, x-coordinate data, y-coordinate data, and z-coordinate data of at least one facet of the predetermined facet pairs to compensate for the predicted dimensional changes in the x-directional strand, the y-directional strand, and the z-directional strand.
