Abstract

Systems, devices, and methods for electro spinning are provided. For example, a system includes a collector including load sensors attached thereto, the collector configured to receive an extruded polymer; and an electro spinning melt head assembly positioned above the collector and configured to extrude the polymer. The electro spinning melt head assembly and/or the collector is configured to move. The melt head assembly includes a syringe assembly and at least one heating element configured to supply heat to the syringe assembly. The syringe assembly includes: a syringe including a passage extending from a proximal end, the passage configured to receive the polymer, and a nozzle configured to allow polymer to pass therethrough.
