Graduate Theses & Non-Theses
Additive Manufacturing (AM) is a technique to produce special products by depositing layers of material in a specific pattern. Wire and arc additive manufacturing (WAAM) is an AM technique that uses welding equipment that has been modified and automated to deposit layers of welding wire. Characterization of specimens produced by WAAM method is required to optimize the process parameters. This research focuses on the microstructure characterization of 308L stainless steel samples produced by a novel WAAM technique known as Plasma Arc Weld Print 3D (PP3D). PP3D consists of multiple plasma arc torches that can deposit material in two modes of …

Additive manufacturing has become a highly researched topic in recent years all over the world. The current research evaluates the merits of additive manufacturing based on the mechanical, microstructural, and fracture properties of additive manufactured AlSi10Mg test specimens. The additive manufactured build plates consisted of tensile and fatigue test specimens. They were printed in the 0°, 30°, 60°, and 90° orientations relative to the build platform. Tensile and dynamic fatigue tests were conducted followed by microstructural characterization and fracture analysis. A wrought 6061 T6 aluminum alloy was also tested for comparison. Tensile tests revealed similar ultimate tensile strengths for all …
