Zusammenfassung:	A printhead and methods for forming the printhead are provided. The printhead includes an additively manufactured printhead structure having multiple sintered material layers that correspond to discrete cross-sectional regions of the printhead structure, where each of the sintered material layers is integrally bonded to at least one other sintered material layer. The printhead further includes a polymer layer attached to a surface of the printhead structure, and the printhead structure includes one or more channels for flowing ink through the printhead structure, the one or more channels forming openings on at least one surface of the printhead structure.
