Exploring the use of Additive Manufacturing in Providing an Alternative Approach to the Design, Manufacture and Maintenance of Interior Rail Components

There is currently limited research on how the introduction of alternative manufacturing methods such as additive manufacturing (AM) might assist rail operators in optimising the design, production and maintenance of various internal and customer-facing components. However, questions also surround the economic viability and production cycle times of AM which may act as a barrier to the adoption of this technology by the rail industry. A review of existing literature and industry sources explore current best practice for AM applications within the rail industry. The areas of design, manufacture and maintenance are explored as potential methods of applying AM to the design of rail carriage customer-facing parts. Outcomes with regards to how costs, production times and labour may be reduced when using this technology are described with a focus on the Australian rail environment. Social considerations such as the usability, comfort and aesthetics of components have also been analysed, while further opportunities for AM’s use in the rail environment are also outlined.
