Fig. 5.

Printability of TGM inks in a 30% Synperonic® bath with different nozzle sizes. (A) Macroscopic images of four-layered scaffolds (left) and microscopic images of two-layered scaffolds (right). (B–E) Fiber diameter, Pr score, shape uniformity, and area uniformity of TGM inks with different nozzle sizes. Groups with a shared letter are not significantly different from each other. Images were selected as closest to the mean of fiber diameter and Pr score. Scale bars in macroscopic images are equal to 1 mm. Scale bars in microscopic images are equal to 250 μm. Dotted lines on graphs represent (B) layer height for nozzle size and (C) ideal Pr score of 1.0. Significance was determined as p < 0.05. n = 5 for all groups. Images and data from groups also present in Fig. 5 are displayed here identically.
