Figure 3. Characterization and demonstration of 3D-printed OPW inks by DIW. (A) Top: Optical images of the printed lines of the OPW inks with varying
xanthan gum concentrations printed at constant pressure. Scale bar: 5 mm. Middle: Height map of the two-layer grid; the height of the printed structure
is indicated by the colors, suggesting the sagging of the 2D grid for O20XG4 and O20XG6. The sample printed with O20XG10 did not exhibit noticeable
sagging. Bottom: Optical images of two-layer grid pattern prints. Scale bar: 1 mm. (B) Plot showing the measured line width as a function of xanthan gum
concentration in the ink after being extruded at a constant pressure. (C) Images of 3D-printed OPW inks demonstrated as food topping, logo display, food
bowl, and mesh cube.
