Easy Sparovation Part
With additive manufacturing, Siemens Mobility Services can make original parts for railway operations for decades – and even improve their design – using 3D data and without tools. We call it Easy Sparovation Part. It opens up new possibilities for replacing and modernizing your parts and improving your vehicles with new components. For example, it can give you replacement parts that are much lighter and stronger than the originals.
With Easy Sparovation Part by Siemens Mobility Services, your replacement parts are made on a metal or plastic printer in just hours, using CAD parts data. Among the many benefits is the fast availability of additive manufactured spare parts: for example, where parts are needed only sporadically, or for unplanned needs resulting from accidents. Even complex part geometries can be made quickly, reliably, and flexibly, in even very small runs. The potential this offers for continuous re-engineering is also of great interest. Additive manufacturing can readily incorporate new findings from actual use, new material technologies, ergonomic improvements, and additional functions – to meet new legal requirements, improve working conditions, or address the changed design expectations of your passengers. This makes the part an improvement over the original.
The data sets are always included in future modifications, so a gapless digital documentation is created as a welcome by-product. This in turn assures you of a fast, smooth manufacturing process in the future as well, even for parts that are only rarely needed.
The production method is called “additive” because the product is made by adding layer after layer. The material used is powdered. After application it is thermally fused to make a three-dimensional form, for example, using a laser beam. This process permits a virtually unlimited variety of shapes to be made, including forms taken from nature (bionics). The process often involves complex material combinations, and can only be managed digitally in high-end industrial applications. With its additive manufacturing infrastructure, consistent digitalization approach, and decades of experience with industrial components, Siemens is at the forefront of the development of this technology.
Additive manufacture of spare parts is of particular benefit:
1. For small runs
2. For high specialization and customization
3. When parts are no longer available due to obsolescence
4. When shipping distances are long: for example, when there is no local manufacturing capacity
Siemens is expanding its global network of high-performance 3D printers, with the objective of printing replacement parts close to customers, quickly and environment-friendly. The vision for 2020: If you as a railway operator somewhere in the world need a hard-to-find spare part, the specs will be sent on the network to the printer that is closest to your location. The product will be printed in just a few hours and delivered to you overnight. The short distance also reduces the CO2 emissions.
Additively manufactured parts by Siemens Mobility Services are already in successful use by railroads, as shown by the following references.
3D print manufacture of ten driver seat armrests for Combino trams, quickly and easily
Extended functionality through integration of switch for setting points - ergonomically optimized design with thumbrest
Addition of the desired switch functionality without added cost, thanks to powder bed melt process (plastic)
The first 3D-printed motor terminal box for high-speed trains, made using a selective laser melt process
Saves storage costs as well as tool and prototype costs for the conventional follow-on production of very small runs
The components made by additive manufacturing are higher in quality than the conventionally-made original, according to H.-G. Kreusch, Senior Consultant Vehicle Technology, Deutsche Bahn AG
