Abstract Acoustophoresis is a versatile, non-contact technique for particle manipulation through acoustic focusing and micromixing and is commonly implemented in acoustofluidic devices. While these devices are traditionally fabricated using labor-intensive planar microfabrication processes, additive manufacturing enables rapid prototyping and complex three-dimensional geometries that expand the design space for acoustofluidic systems. This dissertation is framed around a bidirectional relationship between the two fields: using additive manufacturing for acoustic applications and using acoustics to enhance additive manufacturing. In the first direction, additive manufacturing is used to fabricate acoustofluidic devices by evaluating both the suitability of low-acoustic-impedance polymer materials and the effects of direct fabrication onto piezoelectric transducers on acoustic energy transmission. In the second direction, acoustic focusing is applied to aerosol jet printing to concentrate aerosolized particle suspensions and improve print resolution. Together, these directions explore how additive manufacturing and acoustophoresis can support one another in creating more functional fabrication and particle-manipulation platforms. Ultimately, these studies advance the integration of additive manufacturing and acoustophoresis for acoustofluidic devices and aerosol-based manufacturing. https://hawaii.zoom.us/j/84033585900 Meeting ID: 840 3358 5900
