3D-Printed Syntactic Foams Might Bring Submarines to New Depths

… A new 3D printing method for creating syntactic foams could take submarines to whole new ocean depths. This new method might soon offer underwater vehicle manufacturers the ability to create high-quality parts in complex shapes using commercial 3D printers. … In collaboration with materials scientists from India, Nikhil Gupta—an associate professor of mechanical and aerospace engineering—and his students at New York University Tandon School of Engineering developed this first process of creating syntactic foams using 3D printers. Their goal was to develop a filament for use in commercial 3D printers without the need to change any printer hardware.
