Case Study: Alstom achieves 95% faster on-demand spare-parts production to keep Sétif Tramway running with Stratasys FDM 3D printing

How Alstom leverages FDM technology for on-demand production to ensure continued operation of Sétif Tramway

Alstom, a global green-mobility provider, faced an urgent maintenance problem on the Sétif Tramway when headlights were being damaged by water and stones entering small drainage holes. Alstom’s warranty team turned to its dedicated 3D printing hub and deployed Stratasys FDM technology—using the Stratasys F370 3D Printer and FDM TPU 92A material—to rapidly produce a functional rubber drainage plug solution.

Using the Stratasys F370 and FDM TPU 92A, Alstom designed, printed and delivered a dozen durable TPU plugs within 48 hours (one part printed in under 30 minutes), cutting roughly 45 days from the typical lead time and achieving a claimed 95% time saving. The Stratasys-enabled on‑demand approach avoided expensive tooling, saved about €6,000 in fixed costs, reduced material waste versus subtractive methods, and kept Sétif’s trams operating without long service interruptions.
