By utilizing our unique large-scale 3D printer, we are able to manufacture, at low cost, ultra-multifunctional modular building materials such as interior and exterior panels and architectural resin building materials made from recycled plastic that have functions that exceed those of conventional concrete formwork. We are developing new construction methods that use digital technology to streamline on-site work. With this unique technology, we aim to reduce costs and improve efficiency in the construction industry, and solve issues such as labor issues and waste plastics. It is expected that digital technology will promote architectural process innovation and create an impact on environmental protection and the social economy.
