Abstract
3D-printing, biofabrication, diesel engines, and spray cleaning all depend on controlled drop impact. However, surprisingly, these drops have received scarce attention so far. This is mainly due to their small size and high impact velocity, which makes visualizing the impact a challenge.
This thesis describes methods to generate and visualize the impact of single, high-speed (faster than 10m/s) microdrops (smaller than 100μm in diameter). The impact dynamics are visualized in detail, and numerically modeled. The results are applied to optimize deposition of cell-containing drops used in biofabrication and burn treatment. Finally, by precisely controlling the impact of metal microdrops, fabrication of gold and copper micropillars is enabled.
