Figure 6.

3D-LSM image of a 5 × 5 array of ink droplets transferred by BA-LIFT onto a glass substrate. Z-axis is scaled by a factor of 10 compared to x and y axes. Process parameters: λ = 515 nm wavelength and $E_{\mathrm{p}}=$ 1.75 µJ, gap between donor and receiver $d_{\mathrm{G}}$ = 200 µm, film thicknesses $d_{\mathrm{D}}$ = 1.55 µm liquid donor, and $d_{\mathrm{PI}}$ = 3.5 µm polyimide.
