3-D printing breakthrough for lightweight syntactic foams could help submarines dive deeper

(NYU Tandon School of Engineering) A team of materials scientists at NYU Tandon School of Engineering have developed the first process to 3-D print components of syntactic foam, extremely strong and lightweight composites used in vehicles, airplanes, and ships. The team developed syntactic-foam filaments and processes to 3-D print them using off-the-shelf commercial printers. Their breakthrough holds particular promise for submarines because it will enable manufacturers to print components with complex shapes capable of surviving stresses at greater depths.
