Aerospace additive manufacturing
Aerospace additive manufacturing - 08 July 2016
The introduction:
Some of the most exciting applications of additive manufacturing (AM) can be found in the aerospace sector. Machinery profiles some of the many R&D projects currently ongoing behind the scenes. Airbus, in particular, is engaged on multiple fronts, we discover
Last year, Airbus began an ambitious project with UK supplier GKN to flight-qualify a 3D printed titanium structural bracket for its A320 aircraft (www.machinery.co.uk/110930). Doing so uses far less valuable titanium compared to milling the parts from plate, and is quicker because no moulds need to be made. Parts made by additive manufacturing using Arcam (01926 491300) powder-bed technology have been found to perform as well, or even better, in terms of fatigue life, after post-processing.
Much of that project is concerned with changes involved in scaling up production by a factor of 20 or more to achieve production volumes required. This is essentially a matter of quality assurance: ensuring that the process offers adequate reproducibility and repeatability. Airbus is also broadcasting what it is learning to its design engineers, to instruct them how AM can be used to make new kinds of aerospace parts.
The company’s goal is to print one tonne of metal powder a month in 2018, according to Airbus’s head of emerging technologies and concepts, Peter Sander.
