Abstract
We built an electrospinning apparatus that integrates conventional electrospinning components with an FDM 3D-printing configuration, including real-time 3-axis control to improve accuracy and precision in nanofiber deposition over conventional far-field electrospinning. We motion-synced the spinneret needle and ground needle, incorporated a silver-coated stabilizer on the spinneret needle, and placed an aluminum-surfaced disc on the ground needle. Tests were executed to optimize accurate and precise, dry nanofiber collection at a typical flow rate and applied voltages. Our computer-controlled prototype maintained typical nanofiber characteristics obtained with far-field electrospinning while demonstrating it is capable of accurate stationary deposition and dynamic geometric patterning.
