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)....

Automated semantic segmentation of NiCrBSi-WC optical microscopy images using convolutional neural networks
Download2022-01-01
Rose, D., Forth, J., Henein, H., Wolfe, T., Qureshi, A.
Convolutional neural networks (CNNs) were used for the semantic segmentation of angular monocrystalline WC from NiCrBSi-WC optical microscopy images. This deep learning approach was able to emulate the laborious task of manual segmentation effectively, with a mean intersection over union (IOU)...

Changing Landscape Coatings for Bioactive Bone Fixation Implants via Flame Spray Deposition
DownloadFall 2013
Owing to the bio-inert nature of load-bearing alloys and the brittle nature of bioactive materials there is a need to develop a composite bioactive material suitable for load-bearing applications. To fulfill this need, a new composite coating of a load-bearing alloy and a resorbable bioactive...

Design and Development of a Novel Tensile Testing Apparatus for Time-Resolved Betatron X-Ray Tomographic Imaging
Download2022-06-01
Arce-Borkent, Alvaro R., Richards, Tait, Senthilkumaran, Vigneshvar, Beier, Nicholas F., Zhou, Le, Moore, John A., Knudsen, K. Steven, Hussein, Amina E., Lipsett, Michael G.
High-resolution imaging of deformation processes in materials under load requires controllable and stable loading conditions and the ability to vary sample orientation relative to the imaging source. A novel tensile testing apparatus has been designed, developed, and characterized for...

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...

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...
