Lecture
This lecture covers the process overview of Laser Powder Bed Fusion (L-PBF) of metals, including powder production, processing, thermal history, main issues, and solutions. It explores the advantages of Additive Manufacturing (AM) in aerospace and automotive applications, showcasing examples like fuel nozzles and roof brackets. The lecture delves into the use of AM in biomedical applications, focusing on hip prosthesis design requirements and the benefits of AM in reducing stress shielding. It also discusses the palette of metals for AM, AM processes for metals like Powder Bed Fusion and Directed Energy Deposition, and the comparison between Electron Beam Melting and Laser Powder Bed Fusion. The lecture concludes with insights into powder production methods, powder requirements, and key process parameters for successful metal AM.
