The Science and the Practice of Metal 3D Printing

Please note: this course will not be offered during the Academic Year 2023-24

Metal 3D printing is an emerging technology that is enabling novel solutions in several industries, such as aerospace, automotive, medical devices, and consumer products.

This course provides the scientific basis and the engineering practice principles of this technology, with emphasis on the most widely available one, Laser Powder Based Fusion.

Understand the physical and metallurgical principles involved in metal 3D printing, and how they determine the quality of the printed component. Learn how to take these principles into consideration when designing and evaluating the performance of a printed part. Use simulation tools for innovative designs and process physical modeling. Design, prepare and print a part in the laboratory part of the class.

Some of the lectures will be delivered by leading experts in industry to highlight current challenges and opportunities.

Topics Include

• Laser types and optics
• Light interaction with matter
• Melt pool dynamics
• Solidification and microstructure generation
• Methods of powder preparation
• Part characterization
• Strategies to print a new material
• Tools to create innovative designs
• Simulation tools for physical modeling of the process

Note: Take the course for 4 units if you plan to take the lab (this requires in-person attendance).
