Fig. 5: Two sets of micro-cube arrays with changing laser power on the Y-axis and changing scan speed on the X-axis.

a–f Schematics showing the parameters used to print the two different arrays; (b–e) SEM images of micro-cube arrays printed with each macromolecule using lower scan speeds and laser powers; (g–j) SEM images of micro-cube arrays printed with each macromolecule using higher scan speeds and laser powers; scale bars = 20 µm.
