Abstract
Additive Manufacturing offers a high potential in aerospace industry due to its freedom of
design and the ability to manufacture complex and lightweight parts. The low number of
units, high quality standards and fast response time are special challenges that have to be met
especially in the Maintenance, Repair and Overhaul sector. Thus, companies have to decide at
which point it is economic to apply Additive Manufacturing. However, companies lack
experience on this new technology. This is why a tool is required that takes into account the
above mentioned crucial points and supports the decision process. The paper analyzes
aviation’s characteristics with regard to Additive Manufacturing. The structure of current
MRO repair workflows is investigated to identify a feasible application for Additive
Manufacturing. Additionally the supply chain will be examined to indicate the benefit which
the technology can generate in this highly demanding field. The findings are integrated into a
methodology that supports the decision whether to apply Additive Manufacturing on the basis
of costs, time and quality.Mechanical Engineerin
