A system that utilizes a component that controls thermal gradients and the flow of thermal energy by variation in density is disclosed. Methods of fabricating the component are also disclosed. The component is manufactured using additive manufacturing. In this way, the density of different regions of the component can be customized as desired. For example, a lattice pattern may be created in the interior of a region of the component to reduce the amount of material used. This reduces weight and also decreases the thermal conduction of that region. By using low density regions and high density regions, the flow of thermal energy can be controlled to accommodate the design constraints.
