Abstract
Laser treatment on surfaces of a printhead. In an embodiment, a printhead comprises an assembly of structural elements each comprising a metal substrate. The structural elements form a plurality of jetting channels and a manifold fluidly coupled to the jetting channels, and the jetting channels and the manifold have internal surfaces internal to the printhead configured to contact a print fluid. The printhead further comprises a laser-altered surface texture formed directly on one or more of the internal surfaces via a laser treatment to define one or more wetting regions on the one or more of the internal surfaces.
