The sky is not the limit for the technology — engineers also plan to use it in space.The future Ariane 6 rocket of European space agency ESA, set to blast off from 2020, is set to feature many printed pieces.‘Radical innovations’The new 3D printers can make pieces up to 40 centimetres (15 inches) long and is of most use in particularly complex designs.The metal parts produced can also be 30-50 percent lighter than in the past, and there is almost zero manufacturing waste, added Henzler, who is managing director for Hofmann industrial prototyping.phys.Source: www.Charmeau said Airbus is testing how to print an plastic mold parts suppliers injection assembly for an engine that is now assembled from 270 individual pieces.“The printed pieces have the advantage of requiring no tools and that they can be made very quickly,” said Jens Henzler of Bavaria-based Hofmann Innovation Group, which specialises in the new technology. As a result of this, the Ariane 6 may have half the price tag of its predecessor Ariane 5.
Aside from the costs savings, 3D printing also promises ecological benefits as lighter jets use less fuel and spew out fewer pollutants.To reducing carbon emissions in aviation — with air traffic expected to double in the next 20 years — “the decisive issue is radical technical innovation in a relatively short time,” said Ralf Fuecks, head of the Heinrich Boell foundation think tank of the German Green Party. The little plane “flies beautifully, it is very stable,” said its chief engineer Gunnar Haase, who conducted Thor’s inaugural flight last November near the northern German city of Hamburg. Windowless, weighing in at just 21 kilos (46 pounds) and less than four metres (13 feet) long, the drone Thor — short for “Test of High-tech Objectives in Reality” — resembles a large, white model airplane.“With 3D printing, it has just three parts,” he told AFP.
