Hitachi, the Japanese multinational manufacturer, opened its $100M carbon-neutral railcar factory in Hagerstown, Md., this week that features in-house spare-part and tool-making capacity using Roboze industrial FDM 3D printers. The Roboze Argo 500 will supply the plant with parts in Ultem and carbon-fiber PEEK to replace traditionally machined metal parts. Hitachi Rail will deliver several fleets of railcars from the new digital factory, including over 600 railcars for Washington D.C., Baltimore and Philadelphia.
