1. A composite component for a gas turbine engine, the composite component comprising:
an additively printed inner portion defining at least one flowpath feature, wherein the additively printed inner portion comprises SiC,
wherein the additively printed inner portion comprises a plurality of monolithic layers comprising SiC;
a ceramic matrix composite (CMC) outer portion formed on the additively printed inner portion such that the CMC outer portion substantially surrounds the additively printed inner portion and defines an outer surface of the composite component, and wherein the additively printed inner portion defines at least part of the outer surface of the composite component,
wherein the CMC outer portion comprises a fiber-reinforced ceramic matrix and defines at least one cooling cavity fluidly coupled to the at least one flowpath feature of the additively printed inner portion, wherein the fiber reinforced ceramic matrix comprises SiC.
