Japan’s Hatsushima station, served by the Kisei main line, has replaced its aging wooden shelter with a new 3D printed structure. Built by construction firm Serendix, this modern shelter was completed in under six hours, a significant improvement over traditional construction timelines. The new structure is crafted from layers of mortar reinforced with steel, providing not only durability but also resistance to earthquakes.

Although the entire build process took about a week to assemble and test materials, the on-site installation was remarkably rapid. The first train is slated to pass through the station at 5:45 am, with passengers expected to enjoy this upgraded shelter by July after the final touches, such as ticket machines, are installed.

A noteworthy aspect of this project is the reduced manpower required for assembly, highlighting the efficiency of 3D printing technologies in urban infrastructure. As Ryo Kawamoto stated, “We believe that the significance of this project lies in the fact that the total number of people required will be reduced greatly.”
This innovation serves as a model for future infrastructure projects across Japan and beyond.
