A method of determining a type of support structure for a three-dimensional (3D) object formed by additive manufacturing includes receiving solid model of the 3D object; performing a geometric analysis of the solid model to identify a region of the 3D object requiring a support structure; performing stress and warping analyses of the solid model at the region so identified, including one or more heuristic algorithms applied to the solid model, and excluding finite element analysis of a corresponding finite element model of the 3D object; selecting a type of support structure to place at the region so identified, the type of support structure being selected based on the stress and warping analyses so performed; and generating a shell of the 3D object based on the solid model, and including the support structure at the region so identified and of the type so selected.
