(Construction) - Japanese construction company Obayashi Corporation has completed a 3D-printed building at the company's Technical Research Institute in Kiyose, Tokyo, which makes the first building in Japan to be certified by the Minister of Land, Infrastructure, Transport and Tourism under the Building Standards Law as a 3D printed building using cement materials.
The floor slabs and walls were constructed using a 3D printer filled with "Slimcrete," an ultra-high-strength fiber-reinforced concrete that hardens at room temperature. The building will be open to public as a facility to promote 3D printing technology.
The "3dpod" was constructed using a 3D printer to build all of the above-ground structures with the company's room-temperature-curing ultra-high-strength fiber-reinforced concrete. It is a one-story building with a floor area of approximately 27 square meters. The building has curved surfaces and is intended to be used as a normal building. Multiple layers of walls allow for the placement of cables and plumbing, as well as air conditioning, lighting, and washrooms.

In addition to enabling the construction industry to produce complex curved surfaces and other well-designed shapes, 3D printers are expected to reduce carbon dioxide emissions during construction by eliminating the need to transport materials to the site, and save labor by automating construction. The company plans to utilize the know-how gained through the acquisition of this ministerial certification to construct structures with multiple floors and larger areas. In the future, the company hopes to explore a wide range of possibilities, including construction in space using 3D printers. (2023/04/25)
