TOYOTA, Japan, Jan 12, 2026 – Roboze said its ARGO 500 HYPERSPEED and ARGO 1000 HYPERMELT platforms earned Japan’s Nannen-sei certification for ULTEM 9085. The approval confirms compliance with the Ministerial Ordinance Technical Standards for Railways issued by MLIT (Article 83), following qualification tests at the Japan Railway Rolling Stock Machinery Association (JRMA), with support from SOLIZE PARTNERS Corporation.
Japan’s Nannen-sei certification defines fire safety levels for polymer materials used inside railway vehicles, including panels, covers, air ducts, and other components. Tests confirmed that ULTEM 9085 meets flame-response standards when printed on both Roboze platforms. The material showed consistent performance using filament extrusion on ARGO 500 HYPERSPEED and pellet extrusion on ARGO 1000 HYPERMELT. The consistency demonstrates quality and repeatability in regulated railway environments such as the Japanese railway market.
“We are proud to have supported Roboze in the qualification process according to the Nannen-sei standard,” said Junpei Kise, AM service general manager at SOLIZE PARTNERS Corp. “The Japanese railway sector demands precision, quality and maximum reliability: characteristics we clearly identified in Roboze technology. This certification is an important step toward broader adoption of additive manufacturing in our market.”
Nannen-sei validation allows Japanese railway manufacturers to integrate Roboze additive manufacturing into production workflows with safety, reliability, and operational continuity. The certification supports localized, on-demand production of components, reducing procurement time and logistics costs. Lightweight parts also improve vehicle efficiency and support lifecycle management for scheduled and unscheduled maintenance.
“Achieving Nannen-sei certification in Japan is another important step toward Roboze’s mission of bringing additive manufacturing into the most regulated and high-performance industries,” said Davide Schiena, EMEA Mobility, Aerospace & Defense business development manager at Roboze. “Japan is an extremely rigorous market in terms of safety and reliability. Securing this validation demonstrates the value of our systems and opens new opportunities for international collaboration.”
