The influence of CBP on the printability of GelMA-CBP inks was assessed at 0.1, 0.25, and 0.5% CBP, while keeping the concentration of GelMA at 5% (Figures ). The cylinders printed with 0.25 and 0.5% CBP showed good shape fidelity and structural integrity, and both inks had good printability values. On the other hand, we found that 0.1% CBP was not enough to print 5% GelMA under the experimental conditions used (15% 405 nm light and 0.5% LAP). The cylinder-like construct collapsed, and it was not possible to print a mesh without a considerable deformation of the filaments. Therefore, the printability of 5%GelMA-0.1%CBP ink was assigned the value of 0.
