Suppression of Filament Defects in Embedded 3D Printing.

Although embedded 3D printing increases the printable materials space to low-viscosity fluids, it also poses new challenges. We investigate the effects of ink and support rheology, print speeds, and interfacial tension on individual filaments by using digital image analysis of in situ videos of the printing process and photographs of filaments right after printing. We find that if both the ink and support are water-based, the local viscosity ratio near the nozzle controls the filament shape. If the ink is oil-based and the support is water-based, the capillary number, or the product of the ink speed and support viscosity divided by the interfacial stress, determines the filament size. Still, inks at nonzero interfacial tension with equal viscosity ratios can be more beneficial, since they result in more rounder and smoother filaments than inks at zero interfacial tension with similar viscosity ratios.
