The implications of these observations are substantial, as the solution to a challenging EHD printing limitation is low-cost and simple, using masking to partially pattern a conductive metal on a glass microscope slide. A major limitation in EHD printing therefore appears to be circumvented using a capacitance-like collector. To date, the smallest gap between single lines for MEW has been reported to be 33µm for PCL and is typically much higher for continuous fibers generated from solvent-based EHD jetting .
