Polyuse Co., Ltd. has raised 1.1 billion yen in unsecured, unguaranteed debt financing from Mizuho Bank and the Shoko Chukin Bank. The funds will support development of its construction 3D printer "Polyuse One." With the raise, cumulative funding now stands at approximately 5 billion yen, following a Series B equity round of about 2.7 billion yen in December 2025.
Polyuse has secured 1.1 billion yen in debt financing from Mizuho Bank and the Shoko Chukin Bank, bringing its cumulative funding to approximately 5 billion yen. The new funds are unsecured and unguaranteed, meaning the raise does not dilute existing shares.
The company will put the money toward its main product, the construction 3D printer "Polyuse One," with the stated goal of using AI to learn from on-site construction data so the printer evolves into what Polyuse calls a "Physical AI" that improves with experience. Polyuse says it has accumulated over 300 construction records, mainly in public works, since its first use in Japan in a Ministry of Land, Infrastructure, Transport and Tourism project in January 2022.
