Serendix
Japanese startup using 3D printers and ABB robots to print homes and railway stations; completed Japan's first 3D-printed house in 23 hours; founded 2018.
Serendix is a Japanese construction technology startup headquartered in Nishinomiya City, Hyogo Prefecture, Japan. Founded in 2018 by CEO Hiroyasu Koma, Serendix is Japan's first company to commercialize 3D-printed housing, deploying large-format construction 3D printers in combination with industrial robots to fabricate building structures.
The company gained international attention in March 2022 when it completed Japan's first 3D-printed house—the "serendix10"—in approximately 23 hours. The serendix10 is a compact spherical dwelling designed to be disaster-resistant and affordable. In 2023, the company began commercial sales of its first model, delivered to Saku City, Nagano Prefecture. Serendix has since introduced the serendix50, a larger 3D-printed home for two-person households, which received the Nikkei Excellent Product and Service Award 2023.
A particularly notable project was the construction of Japan's first 3D-printed railway station shelter at Hatsushima Station in Arida, Wakayama Prefecture, carried out in collaboration with West Japan Railway Company (JR West) and architectural firm Neuob. In this project, an ABB industrial robot was central to manufacturing the prefabricated structural components. The structure was installed overnight, demonstrating the potential of robot-assisted additive manufacturing for rapid infrastructure replacement.
Serendix has entered a capital and business alliance with JR West Group and has purchased multiple new construction 3D printers to expand production capacity across multiple locations. The company is backed by investors including Minato Capital and Minato Bank, and is part of Japan's J-Startup program. Serendix operates at the intersection of additive manufacturing, robotics, and construction automation.

Video Friday: Digit Learns to Dance—Virtually Overnight
In a recent roundup of advancements in robotics, IEEE Spectrum highlighted several notable developments and upcoming events in the field. Among the key innovations is Digit, a humanoid robot that can learn new whole-body control capabilities overnight through sim-to-real reinforcement training, enhancing its performance in various tasks. Additionally, the introduction of GEN-1 marks a significant milestone in robot learning, achieving a 99% success rate in simple physical tasks and drastically reducing task completion time. Unitree has made strides by open-sourcing the UnifoLM-WBT-Dataset, a comprehensive dataset for humanoid robot teleoperation, which has been available since March 5, 2026. Meanwhile, researchers presented MRReP, a Mixed Reality interface that allows users to guide autonomous mobile robots in human-shared environments through hand gestures. In other developments, Sanctuary AI showcased its advanced hydraulic hands capable of dexterous manipulation, while China’s Yuxing 3-06 satellite successfully completed an in-orbit refueling test, paving the way for future satellite servicing. Furthermore, Japan Railway West collaborated with Serendix to utilize 3D printing technology for rapid construction at Hatsushima station, demonstrating innovative solutions to infrastructure challenges. Upcoming robotics events include ICRA 2026 in Vienna from June 1-5, and the Summer School on Multi-Robot Systems in Prague from July 29 to August 4, 2026, providing platforms for further exploration and collaboration in the robotics sector.
