A Fully 3D Printed Waveguide and its Application as Microfluidically Controlled Waveguide Switch
DownloadFall 2016
Hollow rectangular waveguides are employed extensively in microwave and millimeter wave devices owing to their relatively high power handling capabilities and low losses, particularly at higher frequencies, compared to transmission lines. However, the fabrication of such metal waveguides suffer...

A Novel 3D Printed Brace Manufacturing Process for the Treatment of Adolescent Idiopathic Scoliosis
DownloadSpring 2019
Adolescent Idiopathic Scoliosis (AIS) is a three-dimensional spinal deformity with lateral curvature and axial vertebral rotation affecting 1-3% of adolescents. Bracing is a proven non-surgical treatment aiming to stop curve progression. Literature has shown that brace wear time affects brace...

Additive Manufacturing of Shape Memory Polymers: Effects of Print Orientation and Infill Percentage on Mechanical and Shape Memory Recovery Properties
DownloadFall 2017
Material Extrusion Additive Manufacturing (MEAM), also known as Fused Deposition Modeling (FDM), is a manufacturing technique in which three-dimensional objects are built. These objects are built by repeatedly extruding thin layers of molten materials through a nozzle in different paths and...

Deformation Transitions and their Effects on the Long-term Performance of Polyethylene and its Pressure Pipe
DownloadFall 2021
Ductile-to-brittle (DB) transition is of tremendous importance for lifetime prediction of polyethylene (PE). Majority of current methods for determining critical stress for the DB transition of PE products use notched coupon specimens in order to shorten the test timeframe. However, those work...
