3D printing holds enormous potential for the rail industry - especially in spare part production. But unlocking that potential requires more than just buying a printer. It takes the right applications, the right materials, and a deep understanding of long-term costs.
3D printing holds enormous potential for the rail industry - especially in spare part production. But unlocking that potential requires more than just buying a printer. It takes the right applications, the right materials, and a deep understanding of long-term costs.
In this blog, we explore how the miniFactory IGNITE 3D printer offers proven, cost-efficient solutions for rail operators, OEMs, and subcontractors. By combining high-performance materials, full process transparency, and robust technology, miniFactory helps rail sector professionals stay on track - both technically and financially.
Why rail demands more than just any 3D printer?
The rail sector requires manufacturing solutions that are fast, dependable, and compliant with strict safety regulations. This is especially true when it comes to older components, where original production processes may no longer be available, or manufacturing via subcontractors is too expensive and slow. Not every 3D printer or material is suitable. Components for passenger trains must meet stringent safety and flame-resistance requirements, such as EN45545. That’s where miniFactory stands out.
We specialize in 3D printing with high-performance polymers, and our technology is purpose-built to meet these demands. The miniFactory IGNITE enables on-demand spare part manufacturing, reducing storage needs and improving maintenance response times — particularly for aging fleets where agility is critical.
Deutsche Bahn’s view about the benefits of industrial 3D printing:German rail operator Deutsche Bahn has recognized the strategic value of 3D printing in accelerating spare part production. According to DB, additive manufacturing not only improves the availability of rare parts but also enables design improvements based on field experience.
These optimized parts are intended to be certified and added to DB’s official spare parts library. Notably, DB’s Neumünster site has been audited under the new ISO 52920 standard, enabling in-house 3D printing of certified components. miniFactory technology is in active use at the facility.
Why is miniFactory the right partner for rail industry companies
miniFactory has been a trusted partner for rail OEMs and operators for many years. Leveraging 3D printing to gain a competitive advantage has long been at the core of miniFactory’s strategy. Through constructive and long-term collaboration with key players in the industry, we have built a deep understanding of the sector’s specific needs and requirements.
3D printing is a highly viable alternative manufacturing method and when used in the right applications, it can be extremely cost-efficient. The IGNITE 3D printer offers features that make it an ideal solution for the rail sector. It combines a large build volume (600 x 400 x 400 mm), excellent print quality, and an integrated material drying system to ensure optimal process control. In addition, the printer supports EN45545-certified materials and includes the Aarni quality assurance software, which plays a critical role in internal validation and documentation processes.
Planning a 3D printer investment? Let’s make sure you get it right - and get real value.
When investing in 3D printing, especially in a demanding industry like rail, it’s not enough to look at the purchase price alone. The real question is: Do you truly understand what drives the total cost and how to measure the return? Printing materials, service, consumables, additional equipment, system openness - all these factors shape the long-term cost curve. In fact, what looks like a small difference at the start can turn into a 100 000€ gap over five years between two machines that seemed similar on paper.
