3D metal printing allows only fabricate new parts. Aerospace, very advanced in additive manufacturing techniques, now uses 3D laser printing to repair the damaged turbine blades.
The implementation technique differs from printing 3D on a bed of powder. Printing direct laser allows to reconstruct the compressor blades damaged by the impact of a bird for example, or even the wear of components of turboprop planes or helicopters. The technology developed by Alsatian Beam is a new market extremely promising.
The CLAD process ‘prints’ metal on existing parts
These are currently 700 pieces that have been literally rebuilt via CLAD (Construction Laser Additive direct) of Beam Machines technology. Contrary to the impression laser on a bed of powder, a nozzle projects directly metal powder while the laser draws the profile of the piece. Installed in a machine 5 axis, this laser nozzle allows to create parts of much larger than those produced by 3D printers, limited by the size of their container. Better, it is possible to start printing on an already existing part. Can be add an additional function but also in rebuilding a party. The method allowing to reconstruct a damaged blade or or add a few millimeters of metal to a worn parts. Specializing in aircraft maintenance, Chromalloy American who provides maintenance of the turboprop PT6 or PW100 engines which equip numerous devices, including the ATR 42/72. Currently, these are 700 aircraft parts have been rebuilt and lifts in these engines and thus resumed the path of the air. These parts are subject to very high stresses, some spin at a speed of 30.000 rpm. Such a process would wear their service life of aeronautical one-piece from 10,000 to 60,000 hours.
Beam favours the co-innovation for new applications of its technology
The technology CLAD, industrialized and commercialized by Beam, is the fruit of 10 years of research by Irepa Laser (Institut Carnot MICA). To create its machines, Beam Machines relied on the Fives Cinetic ROBOTICIST and Aventis Engineering for integration. Multiple applications for this technology are possible, Beam Machines develops new nozzles specifically for new materials and alloys, depending on the needs. New nozzles and software development are carried out in collaboration between Beam Machines and the future user: ” new nozzle and software that can be developed for a new application, but the preparation of the exhibit, machining, tools of maintains control of thermal cycle are developed by our partner. ‘ explains Emmanuel Laubriat, co-founder of Beamwhich notably hopes to develop new applications for its CLAD machines. Thanks to this collaborative approach, the SMEs of Illkirch part now to conquer the North American with the sale of the first machines in the Canada.
