Roboze ARGO Systems Secure Nannen-sei Certification for ULTEM 9085 Rail Parts

Roboze has secured Nannen-sei certification for ULTEM 9085 components printed on its ARGO 500 HYPERSPEED and ARGO 1000 HYPERMELT extrusion systems, confirming combustion-resistance and fire-safety performance required for onboard railway interior parts under MLIT standards. The qualification, validated through testing by the Japan Railway Rolling Stock Machinery Association with technical support from SOLIZE PARTNERS, covers both filament and pellet extrusion on Roboze machines and clears a regulatory barrier for producing certified panels, air ducts, and covers intended for Japanese railways.

This is a practical win for teams that manage fleets, supply spare parts, or run industrial print farms. Certification means parts printed on these ARGO systems can meet Japan’s regulated safety envelope for interior rail applications, enabling on-demand replacement parts rather than long waits for stamped-molded components shipped from distant suppliers. For operators that face tight maintenance windows and high costs for carrying inventories of legacy parts, localized production with certified materials can choke off downtime and lower logistics overhead.

The testing pathway here is notable: the Japan Railway Rolling Stock Machinery Association conducted the assessments that feed into Nannen-sei acceptance, while SOLIZE PARTNERS provided the technical support that bridged printer capabilities and regulatory test protocols. Roboze’s dual-path qualification for both filament and pellet workflows gives print service providers flexibility in feedstock strategy. That flexibility matters in production-scale scenarios where throughput, cost-per-part, and material handling constraints vary between filament and pellet extrusion systems.

For the 3D printing community in Japan and for international shops looking to enter the Japanese rail market, the certification sets a precedent. It demonstrates that high-performance thermoplastic parts produced on industrial extrusion platforms can satisfy strict onboard safety standards when validated through the proper testing channels. Expect OEMs, MRO shops, and digital warehouses to evaluate ARGO-equipped cells for certified spare parts runs, rapid prototyping of certified interiors, and emergency replacements.

What comes next is practical adoption: certified machine setups, validated slices and process parameters, and supply agreements for certified ULTEM 9085 stock will determine how fast on-demand production scales. For anyone planning installations or service offerings, now is the time to map certification requirements against production workflows and talk to technical partners about turning the Nannen-sei pathway into a production-ready supply chain.
