A manifold structure is formed using ultrasonic additive manufacturing and machining. The manifold structure includes a body having a base plate and a cover plate that define a flow passage therebetween, and a plurality of walls that segment the flow passage into a plurality of channels, wherein each of the walls has a height extending from the base plate to the cover plate and a non-linear length that is elongated relative to a width of the wall and extends in a direction normal to the height of the wall. The walls are wavy in shape to provide enhanced rigidity and stiffness during lamination over the channels.
