Siemens Mobility to leverage Stratasys AM Solution to run its First Digital Rail Maintenance Centre

AM Solution

Siemens Mobility, a division of the German conglomerate Siemens, recently launched its first digital rail maintenance centre – the Siemens Mobility RRX Rail Service Centre, in Dortmund-Eving, Germany. The maintenance centre incorporates a Stratasys 3D printer to produce replacement parts and tooling on-demand. The Stratasys AM solution will be the backbone of the depot’s servicing operation.

With this incorporation, it aims to reduce the manufacturing time of replacement parts by up to 95%. It not only helps in reducing the inventory but also lowers the warehousing costs.

Need for the Stratasys AM Solution

Siemens Mobility installed a Stratasys Fortus 450mc Production 3D Printer to take care of all its service requirements at the new maintenance centre. Stratasys systems have a worldwide reputation for its use in core manufacturing sectors. Large corporations like Lockheed Martin, GKN Aerospace, Dassault Systems, etc. are already using Stratasys systems for its benefits.

RRX Rail Service Centre officially opened on 6th September 2018, and Siemens Mobility expects a huge load of around 100 trains per month. Considering the immediate pressure it puts on the entire supply chain, the company has built a robust production and process plan with the necessary world-class machines to operate seamlessly. To fulfill this rapid and wide-ranging demand quickly and cost-effectively, Siemens Mobility needed an AM solution like what Stratasys offers.

Thus the company invested in a Stratasys Fortus 450mc Production 3D Printer which will be able to rapidly print parts and run continuously for longer periods of time with the same reliability.

According to Michael Kuczmik, Head of Additive Manufacturing, Siemens Mobility GmbH, Customer Service, “We believe our RRX Rail Service Centre is the most advanced train maintenance centre in the world. Bringing together a range of innovative digital technologies, we can significantly increase the efficiency of our customer’s rail operations. Stratasys FDM additive manufacturing plays an integral role, enabling us to optimize spare parts for longer life cycles, at a reduced cost, and in shorter timeframes than ever before.”

Increased Customer Responsiveness with Customized AM Solutions

Prior to using 3D printing systems, Siemens would fulfill the customer demands through traditional manufacturing methods like casting but these were time-consuming processes and would take around six weeks to manufacture a customised part. This not only resulted in long lead times but also it became financially impractical.

According to Kuczmik, “the ability to 3D print customized replacement parts on-demand has increased its flexibility to meet customer requirements.”

He added, “Every train has to go through maintenance several times a year. As you can imagine, all our customers would like this process to be as quick as possible, but they still expect maximum levels of detail, safety, and quality in the work we do. We also have to consider unplanned or last-minute jobs, and if you look at the different train models and companies we service, this requires a lot of customized solutions. This is where our AM solution fits in perfectly, providing us the ability to rapidly and cost-effectively produce one-off, customized production parts,” comments Kuczmik.

Tina Eufinger, Business Development Additive Manufacturing, Siemens Mobility Division commented, “Using the Fortus 450mc 3D printer we can 3D print spare parts in a matter of hours. Parts that took 6 weeks, can now be produced in 13 hours. Within a week, we can iterate and optimize the design and then 3D print a final, customized production-grade part. This has enabled us to reduce the manufacturing time of each part by up to 95%, which has significantly sped up our ability to respond to customers.”

Catering Tooling Needs with Stratasys AM Solutions

In addition to producing replacement parts, the Siemens team is also using the Stratasys AM solution to improve its tooling capabilities.

To ensure quick turnaround of bogies, the Siemens team is rapidly manufacturing one-off tools customized to the requirement in a matter of hours. Siemens is using industrial-grade ULTEM 9085 thermoplastic material for its specific tooling requirements.

Speaking about the applications of the Fortus 450mc 3D printer in tooling, Michael Kuczmik explains, “Well-manufactured connectors are essential tools for the effective and safe maintenance of bogies, therefore finding additive manufacturing materials strong enough to withstand such pressures has been an important exercise. The ULTEM 9085 material is tough, enabling us to leverage all the customization benefits of 3D printing and replace our traditional manufacturing method for this tooling application.

“The ability to 3D print customized tools and spare parts whenever we need them, with no minimum quantity, has transformed our supply chain. We have reduced our dependency on outsourcing tools via suppliers and reduced cost per part, while also opening up more revenue streams by being able to service more low-volume jobs cost-effectively and efficiently,” he concludes.
