Stratasys Ltd announced the launch of FDM® PA6/66-GF30-FR, a new flame-retardant composite material designed to enable rail and transportation manufacturers to produce certified end-use parts and critical spare parts. The new material expands Stratasys’ portfolio of industrial-grade, rail-ready FDM thermoplastics and is engineered specifically for use on Fortus® 450mc and F900® systems.
Rail-Ready Certified Flame-Retardant FDM Material
Developed in response to long-standing collaboration with railway OEMs and service providers, the new material addresses a clear market need for certified, production-ready additive manufacturing solutions that balance compliance, performance, and total cost of ownership. It meets EN 45545-2 HL2 (R22/R23) and FMVSS 302 fire safety requirements, delivering high stiffness and strength suitable for load-bearing, functional rail applications. Customers benefit from the durability, performance, and quality associated with Stratasys-certified parts.
Designed for production environments, the material offers reliable printability, excellent surface finish, and repeatable part quality. Its flame-retardant PA 6/66 base polymer is reinforced with 30% glass fiber, delivering stronger and stiffer performance than PC-FR alternatives and positioning it competitively around materials such as ULTEM™ 9085 resin. Compatibility with SUP4050B breakaway supports enables efficient post-processing and throughput for end-use parts.
“With Stratasys, we can implement additive manufacturing in a controlled, certifiable way, which is essential for the rail industry,” said Lorenzo Gasparoni, 3D Printing Program Manager, Alstom Group. “FDM PA6/66-GF30-FR supports reliable, repeatable production of qualified spare parts, along with streamlined, easy support removal using SUP4050B. The surface finish is exceptional and directly reflects the quality and performance of the parts.”
Rail and transportation manufacturers are increasingly adopting additive manufacturing to support production of on-demand spare parts, reducing lead times and lowering inventory costs, particularly across long-life assets and maintenance operations.
“At Siemens Mobility, we see additive manufacturing as a key enabler of flexible production in the railway industry,” said Christian Ochs, Head of Additive Manufacturing, Siemens Mobility GmbH. “Its ability to produce complex, application-specific parts on demand supports more efficient maintenance, reduces lead times, and enhances lifecycle management across rail systems.”
“Stratasys is strategically focused on mobility, transportation, automotive, and industrial applications, where our high-end additive manufacturing solutions have a real advantage in meeting production and certification requirements. The launch of FDM® PA6/66-GF30-FR demonstrates our excellence in design for mobility applications,” said Rich Garrity, Chief Business Unit Officer at Stratasys. “By expanding our rail-certified FDM materials portfolio, we’re enabling customers to scale additive manufacturing with greater flexibility and confidence, while producing parts when and where they’re needed.”
FDM® PA6/66-GF30-FR is generally available for Fortus® 450mc and F900® systems. Additional specifications and supported applications are available on the product page: https://www.stratasys.com/en/materials/materials-catalog/fdm-materials/fdm-pa6-66-gf30-fr/
