Figure Lengend Snippet: (a) Thermal images of ITO-10 NP samples printed with different parameters, exposed to IR lamp irradiation (100 W@50 cm), acquired ad different times, as in panel (b); sample 25DS 1 L, 25DS 2 L, 25DS 2 L, and 25DS 2 L refer to various combinations of drop spacing (DS = 25, 50 μm) and number of printed layers (L = 1, 2). (b) Thermal dynamics of the same samples, averaged with an ROI (region of interest) of 0.5 × 0.5cm 2 placed in the center of the printed squares. Irradiation with the IR lamp starts at 0 s and ends at 36 s. (c) Evaluation of thermal pattern resolution considering the two different designs “interline” and “linewidth”, performed on a specific printed sample exposed to the IR lamp (100 W@50 cm): interline on the left has widths of 2500, 1000, 500, and 250 μm (from top to bottom); linewidth on the right has widths of 2500, 1000, 500, and 250 μm (from top to bottom). (d) Simulated thermal image of the 25DS 1 L square sample (1 cm side) obtained by finite element modeling (FEM) Multiphysics software. (e) Thermal resolution, evaluated as the gradient of temperature along the x axis at the edge of the ITO square vs substrate thickness and time, obtained by simulation. Timestamp in panels (a), (c), and (d) indicates the time elapsed from IR irradiation starting.

Article Snippet: We implemented a 3D heat transfer model in COMSOL Multiphysics v5.6 in order to investigate the achievable thermal resolution as a function of substrate thickness and exposure time.
