en.Wedoany.com Reported - Stratasys Ltd. has introduced a new flame-retardant composite material, FDM PA6/66-GF30-FR, for the railway and transportation industry. This material can be used to produce certified end-use parts and critical spare parts, and is compatible with the Fortus 450mc and F900 systems.
According to Stratasys, the development of the new material is based on long-term collaboration with multiple railway original equipment manufacturers and service providers, aiming to meet market demand for certified additive manufacturing solutions that balance compliance, performance, and total cost of ownership. The material complies with EN 45545-2 HL2 and FMVSS 302 fire safety standards, offering the high stiffness and strength required for load-bearing railway functional components.
Designed for batch production, FDM PA6/66-GF30-FR delivers repeatable print quality and good surface finish. Based on flame-retardant PA 6/66 with 30% glass fiber reinforcement, its rigidity and strength surpass those of PC-FR material, while also being cost-competitive compared to ULTEM 9085 resin. When used with SUP4050B soluble support material, it significantly improves post-processing efficiency and throughput.
"Through Stratasys, we can implement additive manufacturing in a controlled and certifiable manner, which is crucial for the railway industry," said Lorenzo Gasparoni, 3D Printing Project Lead at Alstom Group. "FDM PA6/66-GF30-FR supports reliable and repeatable production of qualified spare parts, with an excellent surface finish that directly reflects the quality and performance of the components."
Currently, railway and transportation manufacturers are increasingly adopting additive manufacturing to support on-demand spare parts production, thereby reducing lead times and inventory costs—a trend particularly evident in the maintenance of long-life assets. Christian Ochs, Head of Additive Manufacturing at Siemens Mobility GmbH, noted: "At Siemens Mobility, we view additive manufacturing as a key enabler for flexible production in the railway industry. It allows for the on-demand production of complex, application-specific components, supporting more efficient maintenance and enhancing lifecycle management across the entire railway system."
Rich Garrity, Chief Business Unit Officer at Stratasys, stated that the company's strategic focus lies in mobility, transportation, automotive, and industrial applications, where high-end additive manufacturing solutions offer advantages in meeting production and certification requirements. By expanding its portfolio of railway-certified FDM materials, Stratasys aims to help customers scale additive manufacturing with greater flexibility and confidence, producing parts where and when needed.
