Mitsubishi Jisho Design Inc. (Head office: Marunouchi, Chiyoda-ku, Tokyo; CEO: Junichi Tanisawa) is pleased to announce that it has developed a production system called "Regenerative Wood" (hereinafter referred to as "the system"), which uses wood 3D printing and covers everything from design to construction of architecture and furniture, at its design studio and wooden architecture lab. The company is also pleased to announce that it is exhibiting the world's first* wooden 3D printed building, "TSUGINOTE TEA HOUSE," which is positioned as a prototype, at the general reception desk of its head office. *According to our research

Today, as various considerations are being made from various angles regarding reducing the environmental impact and shortening construction times in construction work, 3D printing technology is attracting attention as a new architectural production method. This system is an attempt at resource circulation, turning waste into regenerative material by using wood powder generated during lumber processing as filament (a resin material for molding that is used to output architectural components with a 3D printer).

Using wood powder generated as waste in all wood processing processes, the company manufactures its own wood-based 3D printing materials that ensure the stability of 3D printing. By using wood from near the project site to reduce the CO2 emissions that occur when transporting raw materials, and by reducing the size of the output materials during 3D printing, the company can make them available for general logistics and assemble them by hand, making the entire production flow environmentally friendly.

Mitsubishi Jisho Design, together with other Mitsubishi Estate Group companies, is building a continuous timber utilization network that connects forestry/harvesting to lumbering, planning, design and operation.
We will strengthen this network and promote further use of wood through our "Regenerative Wood" system, which aims to reduce waste generated during the wooden construction and wood-based construction process in buildings and urban environments.
