Applying a voltage to the ink produces an electrostatic force, which pulls the ink out from nozzle to form a cone shape (i.e. Taylor Cone) and ejects a filament from the Taylor cone at the high enough voltage, as shown in Fig. 3 (a).

    Liquid metal infiltration of particulate preforms by processes discussed in Chapter 3.20 this volume, provides an increased range of properties for particulate reinforced MMCs. Particulate loadings ranging from 30% to over 70% by volume are possible through selection of the size of the reinforcement particles as well as the preforming techniques employed.
