Abstract

A nozzle plate contains nozzles, liquid chambers and connection channels between liquid chambers and supply containers for the liquid. All the function regions are produced integrally as a microstructure body by casting from one or more microstructured mold inserts. The smallest implementable spacing of the nozzles from one another can be considerably smaller than in the previously known plates, which allows increased printing density.
