Abstract

At finite Reynolds number, sequences of structures (i.e. pillars or columns) in a channel create a combined secondary flow enabling the precise control of flow cross sectional shape. Using an inertial flow deformation control scheme and previously reported UV polymerization techniques used to fabricate 2D extruded particles, we present a novel fabrication process to create complex 3D-shaped particles. A shaped stream of polymer-precursor and photoinitiator is exposed to orthogonal masked UV light, creating 3D shapes consisting of the extrusion of two 2D shapes. We present the results from numerical and experimental studies on the flow deformation physics and possible shapes achievable.
