Powder Metallurgy for Additive Manufacturing
September 16 - September 18
Additive manufacturing (AM), also termed “3D Printing”, is a digital manufacturing process that uses 3D design data to build objects by depositing material, usually layer upon layer. Often referred to as the third industrial revolution, the advancement of AM technologies has brought a revolutionary change in design, engineering and manufacturing processes.
The rising popularity of AM across various industries has resulted in an exponential increase in demand for metal powders. Metal powders were produced originally for powder metallurgy (PM) processes, which involve consolidation of powders under pressure in dies or molds to form precision parts. Materials now routinely processed by PM include aerospace super alloys, low-alloy steels, and tool steels; some of which are virtually impossible to process by any other means. However, powders produced for PM processes may not be suitable for AM processes, and understanding the powder requirements for both types of processes is a major key to successful applications.
This course provides a comprehensive overview of the science and technology of both AM and P/M processes, the materials used in those processes, geometric flexibility, industrial applications and limitations.
As part of the curriculum, the course will showcase a “powder characterization” demonstration from incoming powder to shape making to evaluation. Advanced test equipment will be demonstrated for characterizing the metallurgical and physical features of the powder and final part at every stage of its development.
