Control of Thermal Distribution in Additive Manufacturing

Additive Manufacturing is a rapidly growing industry. However, the defects generally occurring in parts built through Additive Manufacturing have hindered its way towards a reliable technology for mass production. Most of these defects generally occur through residual stresses building up in the parts during the process. Complex machinery is available which ensures defect free parts but it comes with a trade-off for cost. The aim of this study is to provide a potential cost-effective solution to address the defects and issues arising due to uneven thermal distribution in the AM built parts. A detailed study about the basic understanding of the consolidation mechanism of the Powder Bed based Additive Manufacturing processes and Induction is discussed. The use of induction to selectively control the thermal distribution in these manufacturing process is proposed. Preliminary stage simulations and experiments are carried out to validate the proposal and its scope of application is discussedMaster of Science in EngineeringAutomotive Systems Engineering, College of Engineering & Computer ScienceUniversity of Michiganhttps://deepblue.lib.umich.edu/bitstream/2027.42/145492/1/Master's Thesis Copy Formatted (2).pdfDescription of Master's Thesis Copy Formatted (2).pdf : Thesi
