Siemens Mobility Services, which offers rail maintenance services, has invested in two Stratasys Fortus 450mc 3D printers to produce parts as part of an expansion into Russia.
Siemens Mobility has an ongoing contract to build a variant of its high-speed Velaro trains, adapted to suit the Russian gauge and called Sapsan, for Russian train company RZD. The contract includes servicing and maintaining these trains for the next 30 years. Siemens Mobility has already supplied 16 of these trains since 2009 and has now won an order for a further 13.
Siemens Mobility has developed a system for optimising on-demand parts, called Easy Sparovation Part. Essentially, the CAD data for components can be prepared and stored online so that parts can be produced as and when needed In addition, Siemens Mobility works with customers to improve the spare parts and incorporates the knowledge gained from this into new trains. This also allows the parts to be updated to meet new regulatory demands, or simply to meet changing customer demands.
So Siemens Mobility has also rolled out this Easy Sparovation Part network in Russia alongside the new printers. The two Fortus 450mc machines have been installed in St. Petersburg and Moscow as part of this service to produce parts on-demand. Siemens Mobility Russia has achieved more than 99 percent fleet availability record.
Alexey Fedoseev, Head of Customer Services for Siemens Mobility Russia, commented: “These availability figures would be physically impossible to achieve through external part sourcing and traditional manufacturing techniques alone, but Stratasys’ FDM 3D printers gives us the capability to cost-effectively produce the parts in-house, partially eliminating the need for warehousing or tools for a selected range of items.” He added: “We have already seen the success of the Siemens Mobility ‘Easy Sparovation Part’ business in Germany, where this technology has provided us time-per-part savings of up to 95% compared to traditional manufacturing methods.”
The Fortus 450mc machines can print rail parts in industrial-grade materials, with highly durable properties that can survive Russia’s extreme temperatures. In addition, Stratasys provides materials that are able to achieve the material certification of interior train cabin parts from the industry’s regulatory bodies.
Fedoseev concluded: “The manufacture and delivery of an additional 13 new Velaro trains will see us work on multiple vehicles over a long period of time, and within very strict time constraints. As a result, 3D printing makes for a perfect add-on to aid our production and provides us with the flexibility to replace and create parts ourselves, anytime they are needed.”
