A study on the effect of print parameters on mechanical properties of parts manufactured using additive manufacturing
DownloadFall 2017
This thesis presents an investigation on material-process interaction of vat-photopolymerization processes. The effect of different printing factors on tensile properties is studied. Two vat-photopolymerization processes are considered: Digital Light Processing (DLP) and Stereolithography (SLA)....

Additive Manufacturing and Other Techniques for Fabrication of Foams and Electrically Conductive Polymer Composites
DownloadSpring 2023
In this thesis, two aspects of advanced uses for additive manufacturing and microfabrication are investigated: stretchable electronics and polymer foams. These topics were initially part of an extended project effort to develop new capabilities in deformable, high-frequency antennas and the...

High aspect ratio microelectromechanical structures have been found, in the literature, to collapse due to capillary forces of liquids. In this dissertation, mathematical models are developed to study (i) the collapse of a microstructure represented by a double cantilevered beam (DCB) with a free...

Development of a Multi-material Extruder System to 3D Print Hard Thermoplastics, Soft Elastomers and Liquid Metals
DownloadSpring 2019
Functional sensors often consist of rigid parts, soft rubber-like parts, and mechanically tunable electronic components. As part of a larger project to 3D print tunable antennas, it was tasked to develop a printer that could directly produce 3D stretchable electronics with soft and hard...

Recently there has been great research interest in small soft particles because of their significance in both biology and industry. The term ‘particle’ here is defined as a deformable object with size in the range of nano- to micrometers. Many experimental efforts have been spent on investigating...
