About This Course

Metal Additive Manufacturing has emerged as a transformative technology across aerospace, medical, automotive, tooling, and manufacturing sectors. This MOOC course on Metal Additive Manufacturing provides a comprehensive introduction to the fundamentals and advanced aspects of Metal AM. It begins with an overview of the evolution of manufacturing technologies and establishes the role of AM within Industry 4.0. Learners are introduced to metal AM processes, system classifications, and the advantages and challenges associated with producing metal components using additive techniques.

The course then explores the complete digital workflow—from CAD modelling requirements, mesh repair, slicing, and build orientation to simulation and support strategies. The physics governing metal AM, including melt pool behavior, energy interaction, and microstructure formation, are explained to help learners understand how process parameters influence part quality, defects, and material performance.

Design for Additive Manufacturing (DfAM) forms a major component of the course, enabling learners to apply topology optimization, material selection principles, and structural considerations specific to metal AM. Case studies of optimized real-world components are included to strengthen practical understanding.

The final module introduces modern on-machine sensing and in-situ control systems used for monitoring and improving build quality. Learners study sensor architectures, data acquisition, closed-loop control, and industrial quality-assurance toolkits used in metal AM systems.

By the end of the course, students will gain a strong foundation in digital manufacturing, design strategies, and process control for Metal AM, equipping them for advanced study or industry application in smart metal manufacturing.
