Printing test of hydrogel bioink. A The preparation of four different bioinks (Gel 1, Gel 2, Gel 3, and Gel 4, respectively). Gelatinization was occurred through the physical crosslinking at laboratory temperature. B The multilayer skin scaffold for printing. C The lines of the scaffold were observed under an optical microscope
