Abstract:
1. A layered device for separating particles from ink, comprising: a base layer; a layered stack disposed on the base layer, the layered stack arranged in an ink jet printer and forming a separator that includes a first channel, a second channel, and an arrangement of bars comprising at least two rows of bars, the bars extending laterally with respect to a flow path of the ink in the first separator, the rows of bars offset from one another by an offset fraction, the arrangement of bars configured to preferentially route larger particles having diameters greater than a critical diameter through the arrangement into the first channel along a first trajectory that is angled with respect to the flow path of the ink, an angle of the first trajectory being a function of the offset fraction, and to route smaller particles having diameters smaller than the critical diameter into the first channel or the second channel along a second trajectory that is not substantially angled with respect to the flow path of the ink; and a cover layer.
