Japan built a 3D-printed train station in just six hours to replace an old 1948 structure. Using prefabricated, concrete-reinforced mortar parts printed in a factory, the project addressed labor shortages and aging infrastructure. The new station was quickly assembled overnight, showcasing efficient construction for remote and low-resource areas.

Japan built a 3D-printed train station in six hours to replace an old wooden station that was built in 1948
Japan built a 3D-printed train station because its population is aging, and there are fewer workers available to maintain railway infrastructure.
Many old stations, like Hatsushima, were built decades ago and needed repairs or replacements. Using 3D printing helps solve this problem by reducing the number of workers needed and speeding up the construction process.
This new technology can also help maintain services in remote areas with fewer resources.
They built the station quickly by using 3D printing technology. A company called Serendix printed the parts of the station at a factory in Kumamoto Prefecture. Printing and reinforcing the parts with concrete took seven days. Then, they transported the parts by truck to Hatsushima Station.
In the night, workers started assembling the parts after the last train left at 11:57 PM. Using a large crane, they lifted the preprinted parts and put them together near the old station. By 5:45 AM, the new station was ready before the first train arrived.
They used a special mortar material to print the parts of the station. This material is strong and durable, making it suitable for building structures like train stations. The parts were reinforced with concrete to ensure they could withstand daily use.

3D printing is a way of making three-dimensional objects from a computer design. Instead of carving an object out of a block of material, 3D printing builds the object layer by layer. This process is called "additive manufacturing" because it adds layers of material, one on top of the other, until the object is complete. |

PRACTICE QUESTION Q. Which material is most commonly used in consumer-grade Fused Deposition Modeling (FDM) 3D printers? A) Titanium B) Polylactic Acid C) Stainless Steel D) Ceramic Answer: B Explanation: Polylactic Acid (PLA) is the most commonly used material in consumer-grade FDM 3D printers due to its ease of use, low printing temperature, and biodegradability. It is ideal for beginners and widely used in hobbyist and educational settings. |
