Serendix Inc.
Final Report
In March 2026, Serendix Inc. successfully concluded its project at the Tokyo Metropolitan Government's Transportation Bureau material storage site in Shingashi, Itabashi Ward.
Serendix conducted this project to address the challenges of renovating aging railway infrastructure, utilizing the company's advanced 3D printing technology.
The project involved constructing a section of a station platform
modeled after Sugamo-Shinden Station on the Tokyo Sakura Tram (Toden
Arakawa Line). The 3D- printed components were transported to the site
and assembled within a confined field* ¹ to verify the feasibility of
construction in narrow spaces and assess its practical viability for
adoption in railway facilities.
*¹ A term for a small or narrow plot of land.
Pilot Demonstration in Action
The demonstration project achieved significant results compared to
conventional construction methods: construction costs were reduced by
approximately 29%(*²), and the construction period was shortened by
about 4 months. It also confirmed that construction is feasible even
on a narrow site with a frontage road only 4 meters wide. These
outcomes validated the method's effectiveness for practical
implementation and identified areas for improvement, addressing key
renovation challenges such as cost, timeline, and spatial constraints.
*² A cost reduction of approximately 40% is projected if this
method were applied to the entire Sugamo-Shinden Station renovation.
*³ Based on weather data from March 5, the day the parts were
assembled.
Moving forward, Serendix will leverage the results of this project to promote the adoption of this technology for facilities with significant constraints, both in Japan and internationally.
