Development Of A High Strength Composite Material Using Large Scale 3d Printing Applications Using Waste Plastic And Steel, Naga Sri Madhavareddy
Development Of A High Strength Composite Material Using Large Scale 3d Printing Applications Using Waste Plastic And Steel, Naga Sri Madhavareddy
Electronic Theses and Dissertations
This project focuses on developing a high strength composite material for largescale 3D printing applications using recycled materials like High-Density Polyethylene (HDPE) and Steel 430. This material has applications for in-space manufacturing (the Moon or Mars) as well as large-scale manufacturing on earth. In addition to creating a strong useful material, materials that are easily recycled, but are often not recycled, are used. Recycling plastic and metal reduces pollution, saves resources, reduces waste going to landfills, and prevents the destruction of habitats from the polymerization of new plastic and similarly mining new ore. The percentage of HDPE generated from recycled …
Effect Of Composition And Print Orientation On Thermal Conductivity Of 3d Printed Composites, Cory Jacques
Effect Of Composition And Print Orientation On Thermal Conductivity Of 3d Printed Composites, Cory Jacques
Electronic Theses and Dissertations
Additive manufacturing (AM) technologies have become widely used for rapid prototyping and are beginning to be used for end-use applications. Fused Deposition Modeling (FDM) is a type of 3D printing where molten thermoplastic is extruded layer by layer to create parts. There is an increasing need for improvement and diversification of material properties to further extend the use of AM parts. AM parts have not been commonly used in heat transfer applications due to the limited availability of information on thermal conductivity of materials and the effects of printing orientation. A special apparatus was designed and built to experimentally test …

Material Analysis Of 3d Welded 5356 Aluminum Alloy, Ryan Fouts
Electronic Theses and Dissertations
Metal 3D printing has been reserved for aerospace and high-end automotive industries because of its cost. A gas metal arc welder (GMAW) on a rugged 3D printer frame could make metal additive manufacturing an option for more industries and consumers. 3D welded aluminum has not been examined in depth as an option for additive manufacturing (AM). Extensive tests are necessary to determine the correct settings to use a metal inert gas (MIG) welder for AM. Porosity within the welded material must be evaluated to better understand the additive process. The material properties of 3D welded aluminum will be tested and …
