Schematic melt electro writing process: A pneumatic or volumetric feed is used to extrude a heated polymer through a nozzle. Due to the electrical field, the polymer droplet at the nozzle tip forms a conical shape, the Taylor cone. From the Taylor cone a microscale fiber is drawn towards the collector. Depending on the material feed and the collector speed, the result is a curved fiber path and an offset between fiber release and deposition, the jet lag.
