Aiming to harness the unique capabilities of laser printing, in this study, we present our latest results on the transfer and photo-crosslinking of cell-laden bioinks comprising different hydrogels, using a dual laser beam configuration. Results from different laser sources with ns and sub-ns pulse duration and different repetition rates are also presented to highlight the effect of the laser parameters on the printing and photo-crosslinking of the cell-laden patterns. The printing outcome is correlated with the cell growth of different cell-laden bioinks, while immunochemical staining is also employed to study potential cellular damage.
