3D-Printed Synthetic Foam Submarines Could Survive Stress at Great Depths 


A new process using 3D printing to create components of syntactic foam—extremely strong and lightweight composites holds particular promise for submarines because it will allow manufacturers to print components with complex shapes capable of surviving stresses at greater depths.
Syntactic foams, a mixture of billions of microscopic hollow glass or ceramic spheres in epoxy or plastic resin, are widely used in submarines like James Cameron’s Deepsea Challenger and the next-generation Alvin deep-sea explorer because of their remarkable buoyancy and strength.
