Stratasys launches flame-retardant FDM material for rail and transportation end-use parts
Stratasys launched 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.

Stratasys’ new flame-retardant composite material is ideal for rail and transportation end-use parts.
The new FDM PA6/66-GF30-FR 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.
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.
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.
This new material expands Stratasys’ portfolio of industrial-grade, rail-ready FDM thermoplastics and is engineered specifically for use on Fortus 450mc and F900 systems.
