Polyuse raises ¥2.7 billion in Series B funding

As Japan's only construction 3D printer manufacturer*1, Polyuse accelerates the expansion of its R&D base and the strengthening of its business structure for social implementation

2025.12.2

Polyuse Inc. (Minato-ku, Tokyo; Representative Directors: Takuya Iwamoto / Wataru Ooka; hereinafter "Polyuse") has raised approximately ¥2.7 billion in a round co-led by WiL (World Innovation Lab) and Globis Capital Partners (GCP), with participation from Universal Materials Incubator (UMI), SBI Investment and Daiwa House Ventures. In addition to this third-party allotment of shares, Polyuse will also secure loans from financial institutions.

*1 As a company in Japan that "conducts research and development of the machinery, software and materials related to construction 3D printing technology in-house, and also provides services and implementation support" (as of December 2025)

■ Funding to accelerate our growth phase

Since its founding in 2019, Polyuse has consistently held up "construction in which people and technology coexist" as its corporate vision. Aiming to help address the shrinking and aging workforce in today's construction industry, the aging of social infrastructure, disaster recovery and more, we have pursued comprehensive research, development and social implementation of Japan-made construction 3D printing technology.

Starting in January 2022 with its first use in Japan in construction work under MLIT's jurisdiction, our technology has since been used at more than 200 construction sites, mainly in public works.

In September 2025, we also officially began selling and installing "Polyuse One," our Japan-made construction 3D printer, nationwide. We plan to install 100 units across Japan in FY2025–2026.

The funds raised will be invested primarily in expanding our R&D base and strengthening our business structure for social implementation, to drive further growth of the business.

Comments from investors participating in this round

WiL
Yamato Sasakawa, Principal

Japan is a nation facing a severe labor shortage. The shortage is critical in the construction industry, and among formwork carpenters above all. Polyuse is a startup born to solve this structural problem at its root, one of the pioneers of construction 3D printers in Japan, and we believe it is indispensable to making that solution a reality. Built on Japan's outstanding civil engineering technology, it is a company that can aim for success in the global market. Together with Polyuse, we will co-create the value and shape of a next-generation construction industry in which people and technology coexist.

Globis Capital Partners Co., Ltd.
Shinichi Takamiya, Managing Partner

Polyuse will resolve the rapidly worsening aging of craftsmen and labor shortages in concrete work for civil engineering and building construction. Through a distinctly Japanese approach of closely integrating three technologies, 3D printer hardware × software × materials, it will solve the challenges of rebuilding regional infrastructure that we witnessed firsthand in the recovery of the Noto region. We look forward to taking on major social challenges together with the wonderful team, led by Iwamoto and Ooka.

Globis Capital Partners Co., Ltd.
Mayu Kudo, Principal

We are delighted to have joined Polyuse's Series B round as one of the lead investors. From our very first meeting, we were strongly drawn to the company's bold vision of tackling the structural problem of the worsening shortage of craftsmen in civil engineering concrete work through an innovative approach that integrates hardware. We look forward to working with this dynamic team, led by Iwamoto and Ooka, which combines deep industry understanding, drive and strategic capability.

Universal Materials Incubator Co., Ltd.
Shosuke Kiba, Representative Director & Partner

This funding is an important step for Polyuse to further accelerate value creation. At UMI, we highly value Polyuse's unwavering commitment to customer value and to solving social issues. We look forward to Polyuse continuing to refine its scale and governance, co-creating the industrial foundation for the GX era, and establishing new standards that originate in Japan. We will continue to give our full support to Polyuse as it takes on the challenge of redesigning regions and industries around technology that works on site.

SBI Investment Co., Ltd.
Hiroyuki Ono, General Manager, Investment Department

Following the previous round, we have invested once again. Polyuse is a rare company that develops construction 3D printers entirely in-house, from hardware and software to materials, and through high-precision printing it is helping to solve problems such as labor shortages and aging infrastructure. Since the previous round, its technology has advanced significantly and its track record of construction nationwide has grown. With the support of the powerful new investors who have joined this round, we expect Polyuse to become a company that profoundly changes the future of the construction industry.

Daiwa House Ventures Co., Ltd.
Tetsuo Suzuki, President and Representative Director

Since its founding, the Daiwa House Group has pursued "the industrialization of construction," our point of origin, and has never stopped taking on new challenges. We are advancing production systems in which people and robots work together, and in every era we strive for "technology that is useful to society." Through business co-creation enabled by our investment in Polyuse, we will further advance industrialization technology and DX in the construction domain and contribute to sustainable community development.

■What is a construction 3D printer?

A construction 3D printer is a specialized 3D printer used to construct buildings and structures. Compared with conventional construction methods, it can produce concrete structures more quickly and efficiently, and is expected to streamline the construction process and improve building quality. It is also expected to reduce the labor required and improve safety on construction sites, and it further promotes environmental benefits such as the use of sustainable building materials and the reduction of waste.

Thanks to our continued accumulation of Japan's largest track record of 3D printer construction*2, mainly in public works, along with a wide range of verification data, the number of cases in which construction 3D printing technology is put to effective use in the Japanese market has risen sharply in recent years.
