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

Serendix’s construction technology uses a process called 3D printing with mortar, which involves three steps. First, 3D printing 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 said the station is as earthquake-resistant as reinforced concrete houses. The company built and completed the project in about 2.5 hours, significantly shorter than conventional methods.

The cost of building this 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./.
