A low-profile fluid manifold includes a tunable passive flow control system through intricate internal flow channels. The low-profile fluid manifold is manufactured using stereolithography (SLA) additive manufacturing to rapidly produce and tune the intricate flow channels to achieve the desired flow characteristics. Further, SLA additive manufacturing is used to build up inlet and outlet orifices in the flow direction, creating sealing surfaces for parallel oriented seals and sealing surfaces. The low-profile fluid manifold is manufactured to be air and liquid tight at the required operating pressures, temperatures, and environments, without the use of traditional fittings.
