Fig. 4

Cross-sections of filament interfaces, 5 mm behind the nozzle after 2.5 s of extrusion. Arrows indicate the displacement between the intended center of the filament and the actual centroid. Regions i, ii, iii, and iv indicate trends in controlling variables. iii.N contains Newtonian supports, and iii.HB contains Herschel–Bulkley supports. iv.N contains Newtonian inks, and iv.HB contains Herschel–Bulkley inks. If there is no “$” or “N”, the 40 mJ m−2 cross-section is behind the 0 mJ m−2 cross-section. (A) Newtonian ink and support. The “ideal” cross-section is a circle with the inner diameter of the nozzle, where the top of the filament is at the bottom of the nozzle. This ideal applies to all four quadrants of the figure. (B) Herschel–Bulkley ink and Newtonian support. (C) Newtonian ink and Herschel–Bulkley support. (D) Herschel–Bulkley ink and support.
