Lisa Harouni: A primer on 3D printing

The video discusses the transformative potential of 3D printing, also known as additive manufacturing. It explains how 3D printers work by reading CAD data and building objects layer by layer. The technology, which has been around for nearly 30 years, is becoming more accessible and affordable, allowing for rapid prototyping and mass customization. 3D printing is used in various industries, including healthcare, where it enables the creation of bespoke implants and prosthetics. The video highlights the potential for 3D printing to revolutionize manufacturing by enabling on-demand production and reducing the need for mass production.
