Understanding Metal Additive Manufacturing Processes

This course covers the comprehensive aspects of Metal Additive Manufacturing processes. It starts with an in-depth exploration of the electron beam process and the powder feeding mechanism, highlighting the challenges of handling metal powders and their impact on the manufacturing process. Using the analogy of a tailoring machine's thread feeding mechanism, the course illustrates the complexity involved in wire-fed mechanisms in manufacturing. The course then transitions into a comparison between conventional manufacturing processes and additive manufacturing, discussing the fundamentals of laser and electron beam, their parameters, and their role in the manufacturing process. It emphasizes the importance of understanding the solidification process and its role in producing quality output. The course concludes with a detailed study of phase diagrams in metal additive manufacturing, focusing on various alloys and how they influence the microstructure and service condition of the part.
