Correlation of fluid pressure and microdroplet size in a 3D-printed microfluidic chip
Abstract
This paper reports the droplet formation performance of a 3D-printed microfluidic chip according to fluid pressure. SLA (stereolithography) 3D printer was employed for manufacturing the transparent microfluidic chip from resin. Water in oil microdroplets was produced on a flow-focusing design. Oil and water inlets were driven by a constant pressure source. The droplet production performance of the microfluidic chip was monitored through a microscope. The size of water droplets was determined according to pressure values.
