Melt electrospinning has emerged as an alternative fiber formation technology to alleviate concerns associated with solvents in traditional electrospinning. While more economically and environmentally friendly, this technology still searches for an optimum process for the fibre formation to approach robust industrial applications.

The prototype fibre printing apparatus presented here was constructed by uniting principles of additive 3D printing and melt electrospinning. The apparatus consisted of movable arm holding electric heater and exchangeable heads combined with high voltage to form a positively charged electrode. Such setup is unique and allows for controlling both tip-to-collector distance, voltage, and temperature for melting a polymer. The polymer was fed in a filament form via the filament feeder. Only a small part of polymer filament was heated, thus minimizing energy use and avoiding degradation caused by polymer accumulation in areas of high temperatures. A spinning collector drum served as a negatively charged electrode....
