This simple study helps us understand how we can counteract the effects of draw direction anisotropy (in terms of strength) by applying variable directional stress constraints when optimizing a topology for additive manufacturing. From the two sets of studies performed on the given model, load and boundary conditions, objective and constraints, we can conclude that: 1. The topology of a given solid is sensitive to directional stress constraints. As expected the mass of the design grows to counteract the lower Z direction stress constraint. It retains more material and increases stiffness in the draw direction. This will ensure that the design can compensate for the anisotropy developed during the additive manufacturing process; 2. The topology is also sensitive to changes in the coordinate system where we apply our directional stress constraints.
