New D1 conducted a test to crash a running vehicle here with a house built with a 3D printer. Considering safety, the test was conducted by tying a 2.5t sports utility vehicle (SUV) vehicle to two cranes, hanging it in the air, and colliding it at a speed of more than 50km per hour.
The result was ‘no problem’. Two experiments showed that the front bumper of the SUV was damaged, but the 3D house was not damaged. In particular, the window frames and windows installed on the walls were not damaged.
The company said it started testing to check the strength of the 3D printing building on the same day, responding to some questions about whether the wall constructed like toothpaste through 3D printer nozzles can withstand external impacts.
Earlier, the Gangwon Information and Culture Industry Promotion Agency, Chuncheon City, and 3D architecture company New D1 unveiled a house built with a 3D printer at the same place on the afternoon of the 19th of last month. New D1 showed a house built with a 3D printer and a small red clay house. The first floor of the 33㎡ house was built by connecting a total of four houses, including two 3.5m high columnar frames and two large walls.
In the case of pillars, they were made using a 3D printer and then maintained their strength by inserting rebar directly into them. An official from New D1 said, “It took 3 hours and 8 hours to make frames and walls using 3D printers, respectively.” The second floor of the building is made of panel-type modular assembly materials. It took only 20 days to complete the house, including interior design.
New D1, which has the original technology for architectural 3D printers, has developed architectural 3D printer equipment that can build buildings 6m wide, 5m long and 4m high at once. If you put mortar (building material mixed with sand and water in cement) or loess into this equipment and operate it based on a 3D architectural design, walls and pillars of the house will be made.
If buildings such as houses are built with 3D printing techniques, labor input can be drastically reduced because the construction period is shortened and the process is simplified. The amount of waste generated during the construction process will also be greatly reduced. An official from New D1 said that 3D printing construction can reduce costs such as labor costs and material costs and shorten construction period by 50 to 90 percent thanks to automation of most processes except floor basic work.
Co-CEO Shin said, “In the future, we will prepare a system that can supply affordable housing in a short period of time for young people or the underprivileged who are suffering from housing shortages.”
