Japan's 3D-Printed Station Goes Up Overnight
1A railway company in Japan built a new station building in a single night, using parts made by a 3D printer. West Japan Railway Company installed the building at Hatsushima Station in Arida, Wakayama Prefecture, in late March 2025. The companies involved said it is the world's first 3D-printed station building.
2The parts were not printed at the station. A robotic arm at a factory in Kumamoto Prefecture squeezed out a special mortar, one thin layer at a time. The printer made four hollow sections over about a week. Workers then filled the sections with steel bars and concrete to make them stronger.
3Trains use the line from early morning until late at night, so the crew had only a few hours to work. The last train left at around midnight on March 25. Using a crane, the crew lifted the four sections off trucks and joined them in about two hours. The work ended at around 5 a.m., before the first train of the day.
4The building covers about 10 square meters, or roughly six tatami mats. It is about 2.6 meters tall and 6.3 meters wide. Its curved walls show mandarin oranges and hairtail fish, two local specialties. The new building replaced a wooden one that had stood since 1948.
5A JR West official said building a similar station in the usual way takes a month or two. The station building opened to passengers on July 22, 2025, with a ticket machine, a simple IC card reader and a bench. JR West said it hopes to use 3D printing for other railway buildings as well.

全文訳
1日本の鉄道会社が、3Dプリンターで作った部品を使って、新しい駅舎をたった一晩で建てました。JR西日本は2025年3月下旬、和歌山県有田市の初島駅にこの建物を設置しました。かかわった会社は、これが世界初の3Dプリンター製の駅舎だとしています。
2部品は駅で印刷されたわけではありません。熊本県の工場で、ロボットアームが特殊なモルタルを薄い層ずつ押し出しました。プリンターは約1週間かけて、中が空洞の4つのパーツを作りました。そのあと作業員がパーツの中に鉄筋とコンクリートを入れ、強くしました。
3電車は早朝から夜おそくまで走っているため、作業員が使える時間は数時間しかありませんでした。3月25日、終電は真夜中ごろに出発しました。作業員はクレーンを使って4つのパーツをトラックから持ち上げ、約2時間でつなぎ合わせました。作業は午前5時ごろ、始発電車の前に終わりました。
4建物の広さは約10平方メートルで、だいたい畳6枚分です。高さは約2.6メートル、幅は6.3メートルです。曲線の壁には、地元の名産であるみかんとタチウオの模様があります。この建物は、1948年から建っていた木造の駅舎に代わるものです。
5JR西日本の担当者は、同じような駅舎をふつうの方法で建てると1〜2か月かかると話しました。駅舎は2025年7月22日に利用が始まり、券売機、簡易IC改札機、ベンチが置かれています。JR西日本は、ほかの鉄道の建物にも3Dプリンターを使っていきたいとしています。
文法ポイント：分詞構文（Using 〜, ...）
-ing で始まる部分が「〜して・〜しながら」の意味を表す。本文の Using a crane, the crew lifted the four sections ... は「クレーンを使って、作業員は…」という意味。
