Additively manufactured components including unitary bodies. The component may include a unitary body having a component section. The component section may include at least one passage extending at least partially through the component section. The unitary body may also include a supplemental section formed integral with the component section. The supplemental section may be disposed over the passage(s) of the component section and may include a channel extending at least partially through the supplemental section. The channel may be in fluid communication with the passage(s) of the component section. Additionally, the unitary body may include a transition conduit positioned within the component section and the supplemental section. The transition conduit may extend between the passage(s) of the component section and the channel of the supplemental section to fluidly couple the passage(s) and the channel.
