Methods of fabricating reduced weight components for apparatuses include obtaining a component including a relatively lightweight material; placing at least one stabilizing structure on the component; sequentially applying a plurality of applied layers on the component and the stabilizing structure by applying the relatively lightweight material over the component and applying over the relatively lightweight material a plurality of layers having gradually progressively higher proportions of the relatively heavyweight material than preceding ones of the plurality of layers closer to the component, with an outer layer of the plurality of applied layers including the relatively heavyweight material; diffusion bonding the plurality of applied layers by consolidation of the plurality of applied layers; and cutting component features in the plurality of applied layers.
