Safe & reliable, made in Japan
The machine is a mass-produced unit we develop and build in Japan. Its dedicated materials are also made in Japanese factories, and tested and inspected to domestic construction standards.

What makes Polyuse One different
Point 01
Transportable on a 4‑ton truck
It folds down to fit on a standard 4‑ton truck, so it can be brought right up to the site. Folded, it also stores neatly in a warehouse, letting you scale its use up or down with demand.
Point 02
No expert skills needed to operate
Three days of onboarding get your team running production on its own. After adoption, we keep guiding your training and provide a full range of support through the first year.
Point 03
No complex data design required
Along with freedom of shape, Polyuse supports your data creation, from data design to judging whether a print is fit for use, drawing on a track record of over 300 projects. Build with full confidence in quality.
Point 04
Meets public‑works quality standards
Clears the strength and durability standards that MLIT, prefectures and municipalities require for public works. Its track record extends beyond temporary works to permanent infrastructure.
The Polyuse 3D printing system
A complete support system
We work alongside you from before you adopt a construction 3D printer through to your plans after adoption. Each company gets a dedicated team that supports its own vision, planning and execution.
Over 90% share in Japan
We lead more than 90% of 3D-printed public-works projects in Japan.
Quality
Equal to or better than concrete
Compressive strength meets the level required of ordinary civil-engineering structures. Core specimens taken from printed pieces reached about 40 N/mm² or more at 28 days (under standard conditions).
Dense and monolithic right to the core
Although built up in layers, it forms a monolithic structure densely filled right to its core. Minimizing coarse voids helps secure both mechanical performance and durability.
Usable as formwork for RC structures
Used as stay-in-place formwork, it also bonds fully with the cast concrete, limiting moisture ingress at the interface and contributing to long-term durability.
High durability for long‑term use
Performance holds up even in freeze-thaw environments. In testing it retained a high relative dynamic modulus of elasticity, confirming it can withstand medium- to long-term use.
Technical guidelines & quality standards
For structures built with construction 3D printers, the Japan Society of Civil Engineers (JSCE) has established technical guidelines covering design, construction, and maintenance. MLIT has also issued reference materials on verifying as-built dimensions and quality, along with cost-estimation standards for construction 3D printing, so frameworks for quality control and procurement on real projects are taking shape.

New-technology adoption policy
The MLIT Road Bureau's FY2025 New Technology Adoption Promotion Plan lists construction 3D printing among the new technologies to be promoted in the road sector. As public works take up new technologies, it is a field now moving into practical use on construction sites.

Registered in NETIS
This technology is registered in MLIT's New Technology Information System (NETIS). It qualifies as a new technology that can be proposed for use in public works, making it eligible for adoption and evaluation on actual projects.

How as-built dimensions and quality are verified
MLIT's Technology Research Division has published Reference Materials (Draft) on Verifying the As-Built Dimensions and Quality of Objects Produced by Construction 3D Printers (March 2026). Of the 14 MLIT-managed civil engineering projects cited as application examples in its appendix, 11 were built with Polyuse 3D printers, and the verification methods it sets out were compiled from that accumulated track record.

Status under the Building Standards Act
In June 2026, MLIT Notification No. 693 established standards for treating formwork produced by a 3D printer as a structural part of reinforced concrete construction, so buildings within a defined scale no longer need individual ministerial certification. Polyuse served as a cooperating member of the 3D Printer Response Study Committee, whose work laid the groundwork for the notification.

Technology development plan for agricultural and rural infrastructure
The Technology Development Plan for Agricultural and Rural Infrastructure sets out the direction and concrete measures for the technology development needed to revitalize rural areas. Its aim is to promote practical, socially valuable technologies that help achieve the policy goals of the Long-Term Land Improvement Plan (approved by the Cabinet in September 2025). It covers the five years from FY2026 to FY2030.
