Abstract
A method of extruding a nanoparticle composition onto a substrate is disclosed. A nanoparticle composition dispenser includes a capillary tube. The capillary tube is oriented such that a first longitudinal axis extending through the capillary tube is tilted at an oblique angle relative to a vertical axis. The capillary tube is positioned above the substrate such that the capillary tube and its reflection from the substrate are visible within a field-of-view of a camera. Digital images of the capillary tube and its reflection are captured and processed to detect the first longitudinal axis extending through the capillary tube and a second longitudinal axis extending through the reflection. A point of intersection of the first longitudinal axis and the second longitudinal axis is calculated to estimate a zero-height position. The capillary tube is positioned at a start position in accordance with the zero-height position.
