Reaching greater depths with 3D printing

Syntactic foam is a strong and buoyant material commonly used in the manufacturing of submarines. Now, a team of researchers have developed a method of 3D printing components of syntactic foam that could take submarines to greater depths. Nikhil Gupta, Associate Professor of Mechanical and Aerospace Engineering at New York University’s Tandon School of Engineering, joins Hari Sreenivasan to discuss this innovation.
