Abstract
An additive method of forming a metallic nanoparticle microdot on a substrate is disclosed. The method includes: (A) estimating or obtaining a position of an outlet of a capillary tube at zero height above the substrate (zero-height position); (B) extruding a metallic nanoparticle composition from the outlet at a first height h1 above the zero-height position, including forming a fluid bridge between the outlet and the substrate; (C) optionally lifting the capillary tube relative to the substrate by a height increment of Dh while continuing to extrude the metallic nanoparticle composition from the outlet; and (D) rapidly lifting the capillary tube to separate the outlet from the fluid bridge.
