3D-printed foam parts could stay strong as subs dive deep

A new process uses 3D printing to create components of syntactic foam—extremely strong and lightweight composites used in vehicles, airplanes, and ships. … In two papers published in JOM, the Journal of the Minerals, Metals & Materials Society, Nikhil Gupta, an associate professor of mechanical and aerospace engineering at New York University’s Tandon School’s mechanical engineering department, and collaborators in India report they developed syntactic-foam filaments and processes to 3D print them using off-the-shelf commercial printers.
