Siemens Mobility further invests in Stratasys 3D printers for 30 year rail maintenance project

Having previously utilized Stratasys’ 3D printing systems to fabricate spare parts for the German and UK rail industries, Siemens Mobility Services has increased its investment in Stratasys’ 3D printing technology to expand its rail maintenance operation in Russia.

Two new industrial-grade Stratasys Fortus 450mc 3D printers will be used for spare part production to support the 13 additional high-speed Velaro trains Siemens Mobility will be building for Russian train company RZD.

The 30 year maintenance project

The 13 new trains will be added to an existing fleet of 16, with a 30 year agreement to maintain and service the trains also in the deal. This third Velaro order from RZD will bring the total number of high-speed trains to 29.

3D printing solution to support 30-year digital rail maintenance

Having successfully implemented Stratasys‘ 3D printing to produce parts for the German and UK rail industries, Siemens Mobility Services has continued its investment in Stratasys technology to support the expansion of its rail maintenance operations in Russia. This includes two new industrial-grade Stratasys Fortus 450mc 3D Printers for part production.

The decision comes in line with a recent business win for Siemens Mobility to build 13 additional high-speed Velaro trains for Russian train company, RZD, including an agreement to maintain and service the trains for the next 30 years. This is already the third Velaro order from RZD for Sapsan fleet due to excellent availability of Sapsan trains in daily operation, supplementing an existing fleet of 16 trains.

First 3D printed parts successfully trialled on UK passenger trains

Angel Trains, Stratasys, DB ESG and Chiltern Railways joined forces to trial the first 3D printed parts ever deployed within an in-service passenger train in the UK.

These parts include four passenger armrests and seven grab handles, which have been installed on Chiltern Railways trains. The trial’s success to date demonstrates how 3D printing can help train operators accelerate the replacement of obsolete parts, enabling them to get vehicles back into service quicker and better maintain their trains – improving the quality of service for passengers.

The cross-industry collaboration between Angel Trains, DB ESG and Stratasys aims to leverage 3D printing to help overcome issues around the replacement of obsolete parts across the UK rail industry. Unlike the automotive industry, where vehicles from household brands are mass produced in their millions each year, the number of fleets in the rail industry are comparatively very small and, in some cases, over 30 years old. This combination presents several challenges for train operators, especially when it comes to vehicle maintenance and part replacement.

Siemens Mobility is 3D printing spare parts at first digital rail maintenance centre

“The ability to 3D print customised tools and spare parts whenever we need them, with no minimum quantity, has transformed our supply chain.”

Siemens Mobility GmbH, part of Siemens AG, has opened its first digital rail maintenance centre, eliminating the need for inventory of selected spare parts.

The Siemens Mobility RRX Rail Service Center located in Dortmund-Eving, Germany, houses a Stratasys Fortus 450mc Production 3D printer which is being used produce replacement parts and tooling on-demand. Siemens Mobility has reduced the manufacturing time of select parts by up to 95%.

The RRX Rail Service Center is expecting around a hundred trains to enter the depot every month. Michael Kuczmik, Head of Additive Manufacturing, Siemens Mobility GmbH, Customer Service says 3D printing will play an integral role in optimising “spare parts for longer life cycles, at reduced cost and in shorter timeframes than ever before.”
