EINDHOVEN, NETHERLANDS (AP) – Elise Lucy նոր Harry Deckers’s new home is a 94-square-foot (1,011 square foot) two-story mansion reminiscent of stone windows.
The curved lines of its gray concrete walls look natural and feel natural. But they are actually in the Netherlands, at the latest level of housing technology around the world. They were printed in 3D at a nearby factory.
“It’s special. “It’s an unusual egg. When I first saw it, it reminded me of something you knew when you were young,” Luces said on Friday. He will rent the house for six months with Deckers for 800 euros ($ 970) a month.
For now, the mansion seems strange, with its printed concrete layers clearly visible, even in a few places where printing problems have caused imperfections.
In the future, when the Netherlands is looking for ways to overcome a chronic housing shortage, such construction may become commonplace. During this decade, the country will have to build hundreds of thousands of new homes to accommodate its growing population.
Theo Salet, a professor at Eindhoven University of Technology, is working on 3D printing, also known as additive manufacturing, to find ways to make concrete structures more sustainable. He illustrates that in the future, homes can be 3D printed using 30% less material.
“Why is stability the answer?” He said. – And the first way to do that is to reduce the amount of concrete we use.
He explained that 3D printing can only place material where you need it.
The new generation of start-ups in the United States is also among the companies that want to bring 3D printing to mainstream.
Lutzy Լ Deckers’s new home is located in Eindhoven, a city that is emerging as a hub for innovation.
The house consists of 24 concrete elements, which are “printed” by a machine that pours a layer of concrete on a concrete plant in a city factory before the cargo is moved to another new house. Finishing touches were added there, including the roof.
The layers give a ribbon texture to its walls, inside and out. The house complied with all Dutch building codes, and the printing process took only 120 hours.
The house is the result of a collaboration between the municipality and Eindhoven Technical University և construction companies called Project Milestone. They plan to build a total of five houses, improving their equipment with each. Future homes will have more than one floor.
The process uses the stability of toothpaste through concrete, Salet said. This ensures that it is strong enough to build, but also wet enough for the layers to stick to each other. The printed elements are hollow և filled with insulating material.
The hope is that homes that build faster than traditional homes, which use less concrete, could become a factor in an apartment that is one-third the size of Florida, with a population of 17.4 million. ,
In a report this month, the Netherlands Environmental Assessment Agency said education and innovation could boost the construction industry in the long run. But other measures are needed to address the Dutch housing shortage, including zoning reform.
Salet believes that 3D printing can help by digitizing home design and production.
“If you ask me, will we build 1 million houses, as you see here?” The answer is no. But will we use this technology as part of other homes combined with wooden structures? In that case, my answer is yes, “he said.
Deckers has already noticed a lot of acoustics in the house, even when he is just playing music on his phone. And when he does not listen to music, he enjoys the silence provided by the insulated walls.
“It feels very good, because if you are inside, you do not hear anything from outside,” he said.
