EOS and MTU enter additive manufacturing tech partnership

EOS and MTU Aero Engines, one of Germany's leading aero engine manufacturers, have signed a joint framework agreement to develop new methods of quality assurance for metal engine components produced by additive manufacturing (AM).

Dr Adrian Keppler, head of sales and marketing at EOS, said in a press release: ‘MTU and EOS have been working intensively for several years. This collaboration is now about to develop into an even closer, partner-based technological cooperation.’

The joint operation has already applied optical tomography (OT), developed by MTU, to compliment EOS’ modular monitoring equipment. The camera-based OT technology controls the exposure process and melting characteristics of the material at all times to ensure optimum coating and exposure quality, in addition to monitoring the general system status.

‘The OT solution enables us to perform even more holistic quality control of the metal additive manufacturing process – layer by layer and part by part,’ explained Keppler. ‘A very large proportion of the quality control process that previously took place downstream can now be performed during the manufacturing process, with a considerable saving in quality assurance costs. This also allows us to satisfy a central customer requirement in the area of serial production.’

Thomas Dautl, head of production technologies at MTU in Munich, noted: ‘EOS and MTU are jointly furthering the qualified use of additive manufacturing in aerospace engineering while also reducing costs. The monitoring solution represents a value enhancement not only for EOS technology but also for each and every customer.’
