Investigation of Mechanical Properties, Porosity and Geometric Deviation of Lattice Structures Manufactured by Additive Manufacturing
DownloadSpring 2022
This thesis reports fabrication, mechanical characterization, finite element modeling, and geometric analysis of lattice structures. A net-shaped 316L stainless steel lattice structure composed of diamond unit cells was fabricated by selective laser melting (SLM). The cavities in the lattice...

Large-scale Metal Additive Manufacturing: A Holistic Review of the State of the Art and Challenges
Download2021-01-01
Lehmann, T., Rose, D., Ranjbar, E., Ghasri-Khouzani, M., Tavakoli, M., Henein, H., Wolfe, T., Qureshi, A.
Additive Manufacturing (AM) has the potential to completely reshape the manufacturing space by removing the geometrical constraints of commercial manufacturing and reducing component lead time, especially for large-scale parts. Coupling robotic systems with direct energy deposition (DED) additive...

Manufacturing and evaluation of the tensile properties of 3D printed human hair reinforced composites
DownloadSpring 2023
This thesis proposes a novel method to 3D print human hair-based polymer composites. Human hair is a biological fiber whose microstructure is well-defined. It possesses high tensile strength, thermal insulation, a unique chemical composition, and elastic recovery, among other qualities. However,...

Microstructural Analysis of Ni-WC Metal Matrix Composites Deposited Using Plasma Transferred Arc Additive Manufacturing
DownloadFall 2023
The objective of this thesis is to examine how the composition and solidification rate influences the thermal degradation of WC and the resulting microstructure of WC-Ni metal matrix composites (MMCs) deposited using plasma transferred arc additive manufacturing (PTA-AM). Scanning electron...

Modification of Thermal and Mechanical Properties of Polyhydroxybutyrate (PHB) through Addition of Bio-based Plasticizing Materials and Additive Manufacturing Processing
DownloadFall 2018
The non-degradable polymers currently used for commercial production and application may be inexpensive; however, their excessive use is leading to unprecedented amounts of plastic waste and extensive environmental damage. The demand for biologically-derived, biodegradable polymers is therefore...
