Figure 2 .
2The kC temperature as a function of time during the printing stages: (a) cooling down from the loading temperature to the extruding temperature (the experiment at 40 • C is shown); (b) cooling down of the generated droplet (see text) after extrusion, during the self-supporting stage. The droplet was printed at 40 • C on the printer plate kept at 25 • C. Lines correspond to the best fit of the **data** to Equation(1).
