  • Laminate manifolds for mesoscale fluidic systems
    Patent number: 9555631
    Abstract: Laminate manifolds, and their manufacture. The laminate manifolds (18) include plates (20) arranged in parallel, forming a laminate plate stack (22), with a securing agent (24) securing the plates in the plate stack. At least some of the plates incorporate apertures (26) that are oriented in their respective plates so that when the plates are arranged in the laminate plate stack (22), the apertures define a fluidic pathway (28) that emerges from the laminate plate stack between parallel plates. The laminate manifolds are particularly useful as ink manifolds (14) for inkjet printers (10).
