Residual Stress in Metal Parts Produced by Powder-Bed Additive Manufacturing Processes
In this study, residual stresses from the electron beam additive manufacturing (EBAM) and selective laser melting (SLM) processes, due to repeated thermal cycles, were investigated. Residual stresses play a crucial role in part performance, and thus, it is critical to evaluate the process-induced residual stresses in AM parts. Ti-6Al-4V and Inconel 718 parts produced by EBAM and SLM, respective...
متن کاملPorosity Measurements and Analysis for Metal Additive Manufacturing Process Control
Additive manufacturing techniques can produce complex, high-value metal parts, with potential applications as critical metal components such as those found in aerospace engines and as customized biomedical implants. Material porosity in these parts is undesirable for aerospace parts - since porosity could lead to premature failure - and desirable for some biomedical implants - since surface-bre...
متن کاملMetal Based Additive Layer Manufacturing: Variations, Correlations and Process Control
Additive layer manufacturing is emerging as the next generation in part manufacture. It is being adopted by aerospace, tool making, dental and medical industries to produce and develop new conceptual designs and products due to its speed and flexibility. It has been noted that parts produced using additive layer manufacturing are not to a consistent quality. Variations have been recorded showin...
متن کاملMetal Additive Manufacturing: A Review
This paper reviews the state-of-the-art of an important, rapidly emerging, manufacturing technology that is alternatively called additive manufacturing (AM), direct digital manufacturing, free form fabrication, or 3D printing, etc. A broad contextual overview of metallic AM is provided. AM has the potential to revolutionize the global parts manufacturing and logistics landscape. It enables dist...
متن کاملModeling and Verification of Temperature Distribution and Residual Stress in Laser Aided Metal Deposition Process
Laser Metal Deposition is a novel, robust technique to manufacture or repair complex aerospace parts. However, as this process is very complicated and often operating at very high temperature, the resulting material behavior is hard to predict. The strain and stress induced by large thermal gradients in the fabrication process may cause parts failure such as cracking and distortion, so it is es...
