Japanese train station building set up in just two hours with the help of 3D printing
Earlier this year, we reported on rial operator JR West's plans to create the world's first 3D-printed train station building. In a fitting tribute to the speed this technology affords us, the building is already completely set up at Hatsushima Station on the JR Kisei Main Line in the town of Arida, Wakayama Prefecture, as of July 22.
First, to get semantics out of the way, the building itself wasn't 3D printed; rather, a mold to pour reinforced concrete was printed. However, this technique allows more complex shapes using curves and reliefs to be formed in a small fraction of the time of conventional concrete pouring methods.
Although the result is a somewhat simple-looking building, Hatsushima Station takes elegant advantage of this with a rounded roof and classical-looking trims. A slice of mikan orange made of concrete can be seen on the front, and a concrete relief of a beltfish is on the side, these being two famous foods of the region.
JR West hopes to use this technology to replace a number of its aging buildings, particularly unmanned ones in rural areas such as Hatsushima Station. However, construction projects near train tracks are very difficult, and work can only be done during a six-hour window between the last and first trains of the day. Had the new station building been set up by conventional methods, it would have taken one or two months to complete.
But with the help of 3D printing, the pouring could be done offsite in pieces over the course of seven days. These pieces could then be transported on four trucks to the station for assembly, which only took two hours to complete. Not only that, but about 45 minutes of that time was spent swapping out trucks, so the actual construction work was about one hour and 15 minutes in total.
The new station building is 9.9 square meters and has a ticket machine, ticket gate, and a bench that seats two. Osaka-based company Serendix was behind the concrete formation and is also known for its 3D printed houses.
The successful creation of the new Hatsushima Station building with the help of 3D printing would suggest JR West will continue to replace its deteriorating infrastructure this way. Not only is this new method considerably cheaper and faster, but the buildings look rather nice too.

Japan's Nikkei Stock Average Shares Slide Most in Almost Four Months on US Economic Concerns
TOKYO, Aug 4 (Reuters) – Japanese shares slid the most in almost four months on Monday, as concerns mounted over the U.S. economy and a potential upheaval in domestic politics. The Nikkei 225 Index of shares .N225 sank 1.8% and was set for its steepest decline since April 11. The broader Topix .TOPX declined 1.5%, with a sub-index of bank stocks .IBNKS.T plunging 4.2%. U.S. shares fell sharply on Friday after data showed that the world's largest economy created fewer jobs than expected in July and a new round of punishing U.S. tariffs cast a shadow on global trade. On the home front, speculation grew that Prime Minister Shigeru Ishiba might resign after last month's election defeat. Ishiba has consistently denied plans to step down after his ruling coalition lost its majority in the upper house of parliament, but pressure from within his Liberal Democratic Party is mounting. 'We had very weak job market data in the U.S. and sentiment among investors has darkened,' said Kenji Abe, chief strategist at Daiwa Securities. 'There is some chance that Prime Minister Ishiba may be forced to step down, so I think that's one thing we should watch.' There were 34 advancers on the Nikkei against 189 decliners. The biggest loser was Credit Saison 8253.T with a drop of 8.2%, followed by Yamaha 7951.T, which sank 7.9%. The U.S. Labor Department said the country added 73,000 nonfarm payrolls last month, below economists' expectations, while June's job growth was revised sharply lower. Tariffs that U.S. President Donald Trump imposed last week on dozens of countries are likely to stay in place rather than be cut as part of continuing negotiations, Trade Representative Jamieson Greer said. The tariffs include a 35% duty on many goods from Canada, 50% for Brazil, 25% for India, 20% for Taiwan and 39% for Switzerland. Among the few gainers on the Nikkei, chip maker Socionext 6526.T rose the most, up 3.9%, followed by optics company Hoya 7741.T, which advanced 2.7%.

Expo Pavilion Materials to Be Reused for 3rd Time at Yokohama Horticultural Expo
YOKOHAMA — In a striking move for sustainable architecture, building materials from the Osaka-Kansai Expo's Women's Pavilion are set for their third major international event, as they will be reused at the International Horticultural Expo 2027 in Yokohama. This will mark the third use of the materials – rare in the construction industry – having previously been utilized at the Dubai Expo. Yuko Nagayama, 49, the architect who designed the pavilion, expressed her hope that 'people will consider architectural reuse, especially at the Horticultural Expo, which has the environment as its theme.'The Women's Pavilion, a joint exhibition by world-renowned brand Cartier, the Cabinet Office, and the Economy, Trade and Industry Ministry, aims to promote women's empowerment both domestically and internationally. The exhibition showcases prominent figures, including poets, environmental activists and writers, and immersive video experiences have received significant attention. The reusable components include the white, hemp leaf-patterned exterior, referred to as the facade. The facade is made up of rod-shaped tubes that form the framework, spherical nodes into which the tubes are inserted, and non-combustible membrane materials made of fluororesin. After the Osaka-Kansai Expo closes, the facade — made up of about 7,000 parts in total — will be dismantled and inspected by a contractor in Higashi-Matsuyama, Saitama Prefecture. Then, it will be repaired and transported to the Horticultural Expo venue. The aim to reuse the materials stemmed from Nagayama's desire that 'while conventional buildings are tied to their locations, temporary architecture should be usable elsewhere.' Because the materials are disassembled, they will not require a large storage space. This allows for efficiency in environmental considerations and cost. At the Horticultural Expo, the materials are expected to be used for an indoor exhibition venue in the central symbol zone. This venue is expected to host exhibits from local governments and foreign countries, and the pavilion's exterior is expected to be reproduced with a similar appearance to how it is at the Expo. New leased materials will also be incorporated, with the total floor of the pavilion at the Horticultural Expo area projected to be about 2.5 times larger than the Women's Pavilion. The white building is expected to stand out against the green of the overall venue, creating a space resembling a large forest. Construction is anticipated to begin around winter 2025, with completion by autumn 2026. 'It's gratifying that this will be the third location for the building as movable architecture,' Nagayama said. 'I hope people will consider environmental issues and appreciate the reuse of architecture.' After the Horticultural Expo concludes, there are also plans to consider its use at the Riyadh Expo in Saudi Arabia in 2030.
