On March 26, West Japan Railway Company (JR West) built a station consisting of parts made using 3D printing technology. This is the first station in the world to be built using 3D printing technology.

The company said the station was built at Hatsushima Station in Arida City, Wakayama Prefecture, on the Kisei Railway Line; it is about 2.6 meters high, with an area of ​​about 10 square ^meters . The station consists of four sections produced by Serendix, a Japanese construction company.

Serendix’s construction technology uses a process called 3D printing with mortar, which involves three steps. First, 3D printing technology is used to create molds for station components, such as roofs and walls, from mortar (a mixture of sand, cement, and water). The 3D printer prints the mortar layer by layer, creating the shape of the station components.

Once the molds are made, the manufacturer will place reinforcing steel (often called rebar) into the hollow sections inside the wall and roof structure. This reinforcing steel helps increase the durability of the structure, helping it to withstand force better.

Finally, concrete is poured into the hollow section with steel reinforcement inside to form a strong and durable layer. Concrete is the main material that makes the station strong and resistant to environmental forces, such as earthquakes.

JR West says the station is as earthquake-resistant as reinforced concrete buildings. The company built and completed the project in about two and a half hours, significantly less than conventional methods. The cost of building the station is estimated to be only 50% of that of using reinforced concrete.

JR West said it is considering using 3D printing technology to rebuild other stations.
