Read full description
Polyuse develops and provides 3D printing technology specifically for construction applications, encompassing hardware, software, and services. The firm's core mission is to address critical issues in the construction sector, such as labor shortages due to an aging workforce and the need for rapid infrastructure restoration after disasters. By focusing on "coexisting construction with people and technology," Polyuse aims to update and support a sustainable infrastructure system. The company operates on a B2B model, collaborating with construction companies to develop and implement its technologies, with a significant focus on public works, which constitute a large portion of its projects.
The company's flagship product is the "Polyuse One," a domestically produced construction 3D printer that can be deployed directly on-site. This printer is designed for portability and efficiency, capable of being set up or folded down in five minutes. Polyuse has achieved significant milestones, including being the first to use this technology in public works projects for the Ministry of Land, Infrastructure and Transport and securing registration on the New Technology Information System (NETIS). Since its inception, Polyuse has raised a total of $17.3M in funding over several rounds, with investors including WiL (World Innovation Lab), Globis Capital Partners, and Daiwa House Ventures. The company has carried out over 200 construction projects across Japan and plans to expand the deployment of its "Polyuse One" printers nationwide.
