Since January 2017 he has taken on the technical management of projects in the network and is the contact person for the member′s questions about any technical aspects of Additive Manufacturing. As an industrial engineer loving the digitization, Arvid Eirich is both professionally and privately interested in topics concerning the Internet of things, Big Data and Industry 4.0.


During the years of rapid industrial expansion in Germany, the railway companies were the pioneers of industry 1.0. The first product for mass transportation allowed movement of people and goods over large distances and railway stations were hubs for transport as well as logistics which enabled an economic boom. Other companies wanted to see benefits and were therefore attracted to such hubs, making railways the backbone of industrialization. This industrialization was a disruptive transformation of the market - Can 3D printing repeat this? The German railway service provider Deutsche Bahn AG has been exploring the advantages of additive manufacturing and 3D printing for maintenance since 2015. The results have been very positive and show that 3D printing can improve plant availability by printing spare parts which are obsolete or improve the supply chain. More than 3000 components were printed and put into operation, but the road is long and certain barriers must be overcome to make 3D printing fit for the serial production of spare parts.
