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.

Deutsche Bahn leverages Gefertec 3DMP technology to 3D print spare railway parts

German railway company Deutsche Bahn is integrating metal additive manufacturing 3DMP technology from GEFERTEC to improve the availability of hard-to-procure spare parts.

The 3DMP process was implemented for the first time as part of this pilot project.  According to Dr. Tina Schlingmann, a Senior Consultant of complete railway systems technology at Deutsche Bahn, availability is a big issue for the company. 3DPM is being used to service vehicles for older locomotives, including now obsolete parts.

Digital rail maintenance center demonstrates the increasing influence of 3D printing on modern-day manufacturing

According to press reports, Siemens Mobility GmbH opened a digital rail maintenance center in Germany that will utilize three-dimensional (3D) printing, also referred to as “additive manufacturing.” The rail center will service approximately 100 trains every month. According to Michael Kuczmik, Siemens Mobility’s head of Additive Manufacturing, the use of 3D printing will “rapidly and cost-effectively produce one-off, customized production parts.”

According to sources, the shift to 3D printing at the digital rail maintenance center eliminates “the need for inventory of selected spare parts” and “reduce{s} the manufacturing time of these parts by up to 95%.” Historically, replacement parts were procured through traditional manufacturing methods such as casting, with lead times of up to six weeks. Such procurement methods also typically required high volume orders to be cost effective, which led to unnecessarily higher inventory levels. By using the digital rail maintenance center’s technology, the same parts may now be 3D printed in 13 hours, reducing the need to maintain a significant inventory.

Changing Track: How GE and Wabtec’s transaction will impact 3D printing and railways

What happens when two financial juggernauts in the same industry combine? It seems we are about to find out. Just a few weeks ago, it was confirmed that Wabtec Corporation is entering a definitive agreement to merge with GE Transportation, a branch of General Electric Company. This major transaction will not only boost Wabtec into a Fortune 500, global transportation leader in rail equipment, software, and services, but it will significantly influence the direction of 3D printing with regard to the railway industry as well.

3D printing has cemented itself as a core component in the evolution of railway manufacturing and equipment over the last several years, with several agencies and companies investing research and development resources into exploring further applications for the technology. The Dubai Roads and Transport Authority (RTA) has integrated 3D printing technology as a cost-effective method of creating and developing parts for the train system, including the ticket gates, ticket vending machines, and even the railways themselves as well as other assets across the metro network. In 2013, rail freight operator Union Pacific (UP) began experimenting with 3D printing to create handheld automatic equipment identification (AEI) devices to ensure that rolling stock is properly tracked and assembled. UP has also implemented 3D printing processes to greatly accelerate their production cycles, with parts now able to be 3D printed within mere hours.
