3D printing technology has revolutionized many industries, and the railway sector is no exception. Austria’s federal railway, ÖBB, was facing a significant challenge in finding obsolete components for their trains. However, they found a solution in Chromatic 3D Materials and their expertise in additive manufacturing.

Chromatic’s collaboration with ÖBB resulted in the creation and installation of various crucial components, such as polyurethane bellows, grommets, cable glands, and valve covers. These parts were meticulously crafted using Chromatic’s cutting-edge RX-AM reactive extrusion additive manufacturing platform. The precision design of these 3D printed parts not only enhances the performance and longevity of ÖBB’s trains but also improves passenger comfort.

One notable achievement of this partnership is the reduction of vibrations and the prevention of dust and moisture infiltration. This ensures the seamless operation of ÖBB’s railcars. The parts, made of thermoset polyurethane material, are not only durable but also highly flexible. They offer a perfect seal against air and water, thanks to their ability to withstand varying hardness levels.

Sebastian Otto, Head of AM at ÖBB Train Tech, praised Chromatic’s expertise in printing polyurethane with different hardness levels, making them the perfect partner for this project. Dr. Bart Engeldahl, Managing Director of Chromatic 3D Materials in Germany, highlighted the durability and reliability of their 3D printed materials.

This successful partnership between ÖBB and Chromatic 3D Materials has broader implications for various industries beyond rail transportation. Aerospace, industrial, and defense applications can also benefit from the advancements in additive manufacturing. Chromatic’s commitment to quality is evident in their plans to scale up production of their RX-AM reactive extrusion additive platform, following a significant $3.1 million investment.

The story of Chromatic’s collaboration with ÖBB is an exciting example of how 3D printing technology can enhance efficiency and reliability in the railway industry. By leveraging the capabilities of additive manufacturing, ÖBB has found a solution to their sourcing challenges and improved the overall performance of their trains. This partnership serves as a testament to the possibilities of additive manufacturing in transforming various industries.
