Parametric characterization for fiber suspension. (a) The FFF-printed support structures have a standardized set of geometric parameters of length (L), height (H), and pitch (P) between fibers. (b) Assessment criteria for profile fiber suspension with typical photographs and diagram key. (c) Assessment criteria for in-plane fiber patterning with color coding and illustrative diagrams; uncolored regions of the phase diagrams represent transition regions of in-plane behavior. (d) Phase diagram characterizing fiber suspension behavior for scaffold heights versus voltages. (e) Phase diagram characterizing fiber suspension behavior for initiator separation lengths versus voltages. (f) Phase diagram characterizing fiber suspension behavior for interfiber pitches versus voltages.
