3D printing concrete structures

A research team in Nanyang Technological University, Singapore (NTU Singapore), has managed to 3D-print concrete structures by the utilization of 2 robotic machines.

Last Tuesday, October 17th, the Netherlands inaugurated the world’s first 3D-printed concrete bridge, which is primarily meant to be used by cyclists. The bridge, which crosses a canalized river in the southeastern town of Gemert, is made of 800 layers of reinforced, pre-stressed concrete with a steel cable running through it to handle tensile stress. Constructed in Eindhoven by the Technical University of Eindhoven and the Dutch construction company BAM, it is 8 meters long by 3.5 meters wide and it took around three months to put together, while its life cycle is estimated at 30 years at least. “The bridge is not very big, but it was rolled out by a printer, which makes it unique,” Theo Salet, from the Eindhoven University of Technology. The new bridge is part of the Noord-Om project, a new section of ring road around the village of Gemert linking the existing routes N605 and N272, and hundreds of cyclists are expected to ride over it every day.

3D printing technology is about to bring a housebuilding revolution. Even  two-story building s can now be constructed this way, as the villa shown in the photos below demonstrates.

The first ever 3D-printed residential home was built on-site in just 24 hours in the town of Stupino, near Moscow in Russia last December. Having a cylindrical shape and consisting of a hallway, a bathroom, a living room and a kitchen, this 38 m2 (406 ft2) house had a total cost of $10,134, or $267 per m2. Apis Cor., the Russian company that constructed it, claims that it can last up to 175 years and that a simpler house (ex. a square one) could cost only $223 per m2 ($68 per ft2).

1st 3D Printed Office Building

The United Arab Emirates announced that it will proceed with the creation of the first building to be used as office, the construction of which will be done by a 3D printer.

The first 3D printed estate in the United States is set to be complete by the end of 2017. The ambitious project is being undertaken by New York City architect Adam Kushner, alongside partners including 3D-printing pioneer Enrico Dini and his D-Shape firm. The estate will feature a swimming pool, Jacuzzi, carport and a 2,400 square foot house in upstate New York.
