A printing device receives modeling data that defines a three-dimensional solid model of a component body having a plurality of faces and a plurality of edges. Each of the faces meets another face of the component body at a respective edge of the component body. The printing device interrogates one or more faces of the component body to identify one or more looped geometries, and defines a lattice exclusion area having a boundary formed based at least in part on one or more faces of the component body that correspond to the looped geometries. The printing device generates a printer output of the component body and a lattice support structure for the component body. The printer output of the lattice support structure is outside of the lattice exclusion area.
