German company Trumpf’s laser cutting machine with the two
cutting heads mounted on a crossbar made of special rods that are a
spin-off from Europe's Rosetta comet mission. The 'sandwich rods' have
a lightweight, rigid foam core wrapped in carbon fibre and coated with
thin fibreglass. This make them six times lighter and up to 50%
stiffer than steel. German company Schütze developed this special
technology for ESA’s Rosetta lander’s legs, to secure its safe landing
on Comet Churyumov–Gerasimenko in 2014.
