Course Instructor
SC1237: Additive Manufacturing of Metals – Powder Bed Fusion and Directed Energy Deposition
Additive manufacturing (AM) is rapidly being adopted by industry as a means to fabricate once-impossible components in a matter of days-weeks rather than months. This course presents the key elements of powder bed fusion and directed energy deposition AM. With a focus on the these two, most popular, AM processes, the course will first guide the audience though the digital thread for component fabrication, then to the consequences of hardware implementations, and the effects of post-processing on part quality. In-process sensing and post-process non-destructive evaluation methods will also be covered. Audience members will leave with a high-level understanding of the technology and an appreciation for the many benefits and challenges of metals additive manufacturing.
