A team of materials scientists at NYU Tandon School of Engineering has developed the first process to 3D print components of syntactic foam — extremely strong and lightweight composites used in vehicles, airplanes, and ships. 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. 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.

Defence and shipbuilding in South Australia will not be a “boom and bust” industry, but will support secure long-term jobs and opportunities. That’s according to Andy Keough, former Defence SA chief and current managing director of defence and security company Saab Australia.
Andy, a former submariner, played a key part in lobbying for Australia’s $50 billion Future Submarines to be built here in SA. He says despite big sectors, such as the mining industry, usually experiencing a “boom and bust” pattern, there is a long-term commitment to continue shipbuilding in SA. “We saw it with the upswing of the mining industry which took off with unimaginable riches that have come and gone,” Andy says.
“But here there is now a Federal Government commitment to continuous shipbuilding … and that’s a massive magnet that will continue to draw high quality workers from across Australia and the world. “There aren’t many sectors in Australia that have the assurance that their industry will continue for many decades to come.”
