Abstract
A device for extruding/dispensing materials on a substrate includes a housing with at least two channels formed to facilitate flow. The housing includes entrance ports for each of the channels for receiving different materials. The housing further includes an exit port for co-extruding the materials on the substrate to generate a relatively fine feature with a relatively high aspect ratio.
