Claim One:
1. A method comprising: identifying a source model describing a modeled object having an outer surface; generating a preliminary fabrication model from the source model, the preliminary fabrication model including fabrication instructions for a three-dimensional printer to fabricate the modeled object based on the source model, the modeled object including a preliminary infill that fills interior space within the modeled object with an infill pattern; automatically performing a structural analysis on the preliminary fabrication model, the structural analysis resulting in the identification of a critical point and a corresponding failure mode at the critical point; automatically modifying the preliminary fabrication model without changing the outer surface of the modeled object to adjust the structural integrity of the modeled object with respect to the failure mode at the critical point, thereby producing an updated fabrication model including second fabrication instructions for the three-dimensional printer to fabricate the modeled object based on the source model; and printing the modeled object on the three dimensional printer using the second fabrication instructions in the updated fabrication model.
