Polyuse Inc. (Headquarters: Minato-ku, Tokyo; Representative Directors: Takuya Iwamoto / Wataru Ooka; hereinafter "Polyuse"), a developer of construction 3D printers, printed a catch basin and installed it underground in early June as part of a joint demonstration experiment with Maeda Corporation (Headquarters: Chiyoda-ku, Tokyo; Representative: Soji Maeda; hereinafter "Maeda Corporation").
This is the first attempt in Japan to use a construction 3D printer on a construction site to print and construct a civil engineering structure for actual use.

- Aiming for open innovation across industries and roles
Polyuse, which develops robotics, IoT and other technologies specialized for the construction industry, conducted this demonstration experiment with Maeda Corporation toward the social implementation of construction 3D printers. The goal is real-world operation in the construction industry by combining Polyuse's "comprehensive technical capabilities and speed" with Maeda Corporation's "specialized industry expertise and strong capacity for wide deployment."
In this demonstration experiment, as part of work to replace an aging existing basin, we used the construction 3D printer developed by Polyuse to print on the construction site, and carried the work all the way through to installing the catch basin underground.
Going forward, we aim to contribute to the industry through the use of construction 3D printers and to further accelerate open innovation among companies.

- Results of the joint demonstration experiment
In this demonstration experiment, a cylindrical catch basin for actual use was printed on site with a construction 3D printer.
After it passed watertightness and other tests, it was used in actual work to replace an existing basin.
We also verified the following at the same time.

- About Polyuse's mission
Polyuse is a robotics startup specialized in the construction industry, working together with partner companies across the industry to bring construction 3D printers into real-world use.
Building on this joint demonstration experiment, we are working even more closely with all parties involved and continuously updating our technology as we drive full-scale operation at construction sites across Japan.
Under the concept of "construction in which people and technology coexist," we aim for construction 3D printers to become an everyday part of the construction industry in the near future and to help create a safe and efficient construction environment.
