A method of manufacturing an additively manufactured component may comprise operating an additive manufacturing machine to form a first structure including an elongate portion having a blind design surface, operating the additive manufacturing machine to form a removal tool proximate the blind design surface, wherein the blind design surface and the removal tool are at least partially enclosed by and in contact with a support material, and translating the removal tool along the blind design surface to separate a portion of the support material from the blind design surface.
