Electro-spinning/writing system and corresponding method

A system, the system comprising:

• a print-head configured to eject the polymer material via a nozzle;
• a collector configured to receive the polymer material ejected from the nozzle;
• a displacement assembly configured to adjust a distance between the print-head and the collector;
• and
• a vat containing or configured to contain a liquid, wherein the vat is further configured to receive the collector;
• and
• wherein
• the system is configured to electro-spin/write a polymer material, and
• wherein the displacement assembly is configured to:
• retract the collector and at least a part of the polymer material received by the collector into the liquid in the vat in accordance with a height of the received polymer material during a deposition of the polymer material on the collector, and
• maintain an upper surface of the received polymer material facing the print-head at a target deposition distance above the liquid surface of the liquid during the deposition of the polymer material as the received polymer material on the collector is partially immersed into the liquid, such that a distance between the liquid surface and the nozzle is larger than the target deposition distance.
