(Construction) - Shimizu Corporation has applied 3D printed concrete forms built with laminated fiber-reinforced mortar to the actual construction for the first time.
The concrete molds with free-form curved surfaces were constructed by the 3D printer for four pillars of 4.2 meters high and 2.2 to 2.7 meters in diameter in a short period of time. The company aims to realize on-site 3D printing of the large-scaled form works in the future

The first application of the 3D printing formwork was conducted at the site in Koto-ku, Tokyo. The company built the molds with “LACTM,”the mortar made with sand, cement and reinforced fiber by the 3D printing equipment installed in a lab at the technical center of the company. The molds were designed in the shape twisting from the circular base to the top, changing into a petal shape. The forms were transported to the site after modeled in the the lab, and concrete was placed to complete the pillars.
The use of 3D printing in construction allows any curved surface to be created quickly. As the degree of freedom in design is also dramatically improved, it is possible to create structures with unique designs. (2021/02/05)
