The Noto Reconstruction Office of the Ministry of Land, Infrastructure, Transport and Tourism has featured our 3D printer in the Nikkei newspaper.

The official X account of the Noto Reconstruction Office of the Ministry of Land, Infrastructure, Transport and Tourism and the Nihon Keizai Shimbun have published that our 3D printer has been adopted for the reconstruction of Noto. The official X account of the Noto Reconstruction Office introduces the use of our products in the restoration work of the Noto Expressway. Additionally, the Nihon Keizai Shimbun mentions that structures made with our products are being used for the restoration of roads damaged by the Noto Peninsula earthquake, and that the construction period can be shortened by about two weeks, so please take a look.

Overcoming the 'transportation barrier' and 'construction schedule constraints.' Hybrid underground handholes: a fusion of strength, lightweight design, and speedy construction.
