A different, but configurationally similar technology is melt electrowriting (MEW), that produces well-positioned fibers but leverages a different EHD effect . When applying a high voltage to a fluid column (i.e., a jet), the charges generated can prevent Plateau-Rayleigh instabilities , allowing the flow rate to the fluid column to be reduced . With a thin, stable electrified jet achieved, the nozzle is moved relative to collector to deposit small diameter fibers (typically between 1 to 50 µm) with high accuracy . Using additive manufacturing principles, this microfiber from the molten jet is repeatedly stacked upon each other . MEW scaffolds are tunable with a porosity ranging from 80-98% that are easily populated with cells/tissues .
