A Charge-Based Mechanistic Study into the Effects of Process Parameters on Fiber Accumulating Geometry for a Melt Electrohydrodynamic Process

Abstract: Melt electrohydrodynamic processes, in conjunction with a moveable collector, have promising engineered tissue applications. However, the residual charges within the fibers deteriorate its printing fidelity. To clarify the mechanism through which the residual charges play roles and exclude the confounding effects of collector movement, a stationary printing mode is adopted in which fibers deposit on a stationary collector. Effects of process parameters on generalizable printing outcomes are studied herein. The… Show more

“…Moreover, the residual positive and negative charges are spatially separated or polarized by the electric field. [ 22 ] In this way, there are coexisting repulsion and attraction between the deposited fiber and the positively charged incoming fiber, which, in turn, affects the printing outcomes significantly. [ 20 ]…”

“…Moreover, the residual positive and negative charges are spatially separated or polarized by the electric field. [22] In this way, there are coexisting repulsion and attraction between the deposited fiber and the positively charged incoming fiber, which, in turn, affects the printing outcomes significantly. [20] Although the basic electric theory in dielectric material has been well established in electrostatics, there are still many questions specific to the MEW-enabled scaffold awaiting to be answered.…”

“…On the other hand, the complex interplay of MEW process parameters (voltage, translational speed of the collector, material temperature etc. ) 7,8 as well as residual charges entrapped in deposited fibers causes imprecise fiber deposition, thereby limiting the applications for the MEW process 9 . Currently, continuous efforts have been made to broaden the application of MEW, including decreasing fiber diameter (0.8 μm), 10 printing large volume scaffolds (thickness greater than 7 mm), 11 producing scaffolds with complex geometries, 12 and fabricating tubular structures 13 …”

“…[ 20 ] Second, residual charges entrapped in scaffolds can affect the deposition behavior of the fiber greatly. [ 21,22 ] Because of the residual charges, the fiber deviation is notably observed during the fabrication of scaffolds with a small inter‐fiber distance, [ 22,23 ] or a large layer number. [ 24 ] The processing parameters and scaffold design parameters can affect the printing accuracy.…”
