Abstract: Examples include microfluidic devices. Example microfluidic devices comprise a microfluidic channel, a capillary chamber, and a fluidic actuator. The microfluidic channel is fluidly connected to the capillary chamber. The capillary chamber is to restrict flow of fluid therethrough. The fluidic actuator is positioned proximate the capillary chamber. The fluidic actuator is to actuate to thereby initiate flow of fluid through the capillary chamber.

Abstract: A method of manufacturing a digital dispense apparatus includes molding a monolithic carrier structure, forming cut outs into a planar top surface of the monolithic carrier structure, the cut outs including a reservoir extending into part of a thickness of the monolithic carrier structure and fluid routing to connect the reservoir with a fluid dispense device, and overmolding the fluid dispense device into the monolithic carrier structure on a side of the monolithic carrier structure that is opposite to the reservoir to fluidically connect to the fluid routing.
