Electrowetting and Electrostatic Forces: Elucidation and Advancements for 3D Printing Applications

This thesis is devoted to the experimental and theoretical study of two phenomena, electrowetting and electrohydrodynamics, and their application to an additive manufacturing technique named Direct Ink Writing (DIW). Specifically, the work describes six individual topics exploring these applications and elucidating the significant beneficial gains for practical 3D printing or DIW applications. From the beginning, it is essential to note that DIW comprises two distinct subcategories. These subcategories are classified by their dispensing form, divided into either droplet-based (3D printing) or filament-based (continuous jet) extrusion, with both being examined in detail, having in mind the application of the electric forces.
