Dissolving MEW fibers to make channels. A) A series of images showing the PCL fibers embedded in a hydrogel that are then dissolved away and backfilled with fluorescent dye. B) Fluorescence images of FDM and MEW processed fibers resulting in channels with varying diameters. C) Schematic of inverse molding by curing the polymer PDMS around MEW fibers followed by delamination, for use as D) microfluidic systems.
