3D printing houses - solutions to build convenient and cheap houses

A 5-member family in the city of Nantes, France has become the first family to live in a house built by 3D printing. The house has an area of ​​about 95m ² , and is 'printed' within 54 hours.

being applied in many fields, and one of those areas is housing construction. Thanks to low cost, fast construction time and help to protect the environment, this technology promises to replace the current traditional housing construction technology.

Over the years, engineers and manufacturers have done a lot of research to automate the housing construction process. Some startups have achieved certain success when introducing many sample design models.

The cost of building 3D printing houses is 20% cheaper?

This summer, a 5-member family in the city of Nantes, France became the first family to live in a 3D printing house. This Yhnova house covers an area of ​​about 95m ² , fully meeting the housing criteria to live long in it. Especially, the house Yhnova was "printed" within 54 hours. Contractors only need an additional 4 months to install windows, doors, and roofs.

As developers of this model, researchers at the University of Nantes believe that the next 3D printing house will be built by them in a shorter time, about 33 hours. Construction cost of this house is about 232,000 USD (equivalent to 5.4 billion VND). Compared to the cost of building a normal house of similar size here, the cost of building with 3D printing is 20% cheaper.

It is known that Nantes University has partnered with the City Council and City Housing Association to build this unique 3D home.

Mr. Francky Trichet, in charge of technology and creativity of Nantes City Council, let the BBC know, he is interested and interested in applications of 3D printing technology than houses built with this technology. .

"3D printing technology can be used to build sports stadiums," he said. Yhnova Project also received a grant from the City Council.

A 3D printer is taken to the construction site, after architects and scientists have completed the design. This printer will print each layer from bottom to top. Each wall in this house is printed into two layers of polyurethane synthetic resin (PU) , which is insulating and insulating. The space between these layers will then be filled with concrete, to create a thick, firm wall.

Yhnova is designed to be very modern, with wheelchair access, and all household appliances are controlled by smartphones.

According to Benoit Furet, a professor at the University of Nantes, who heads the project, in the next five years, the cost of building 3D printing houses will be about 25% cheaper. In the next decade it will be 40% cheaper than it is today, as more and more houses are built by 3D printing and improved 3D printing technology, and of course, all meet the regulations on housing construction.

3D printing technology is also very environmentally friendly and can allow engineers to be creative.

Engineers can adjust the shape of a 3D printing house to suit the surrounding area. In Nantes, a newly built, curved 3D printing house that covers 100 year old trees into the house.

In addition, the house is equipped with sensors that help monitor humidity, air quality, and temperature, all of which help reduce the cost of electricity consumption for the home.

According to BBC, Mr. Furet is currently implementing a project to build 18 3D printing houses and a commercial building with a floor area of ​​about 700m ² .

3D printing houses are being built in many places

A group of developers is working on building 3D printing houses in the Netherlands.The Milestone project, implemented by Eindhoven University of Technology and its partners, aims to build 5 3D printing houses in the city of Eindhoven. The first goal of this project is to build a one-story house, then build 3-storey houses.

Project team Milestone said that 3D printing technology applied to housing construction, will allow users to adjust the house to their liking and reduce waste, because this technology requires less construction materials. than.

A company based in Nevada, USA is also printing 3D houses, with plans to send customers in the Bay Area to live in these houses in the next few months.

PassivDom will build a number of 3D printing models with different sizes and technical features.(Photos are illustrative. Source image PassivDom).

PassivDom, a Ukrainian-based construction startup, used robots to print walls, floors and roofs. After that, workers will install windows, main doors, electricity and water systems for the house.

PassivDom will build a number of 3D printing models with different sizes and technical features. These houses do not even need to be connected to external electrical and water systems, because the electricity used for the house will be electricity from solar panels, and stored for use. for household items. Water is collected from air humidity.

PassivDom originally intended to sell the first 100 3D printing houses to customers in January 2018, but the founder and CEO of the company, Mr. Max Gerbut, told Business Insider, the process of producing materials and Construction takes more time than expected. He added that currently, PassivDom has received more than 10,000 orders to build 3D printing houses around the world, and the company's goal is to become an automatic, durable 3D printing house construction company. Traditional home in America.

And in Chattanooga, Tennessee, USA, Branch Technology architecture company is also building their 3D printing model.

Branch Technology uses 3D printers to print walls and roofs, after which construction workers will assemble local components. Named Curve Appeal , Branch Technology 3D printing house model is designed with an area of ​​about 93m2, including a bedroom, a living room and a bathroom. However, this project is still in the research and development stage.

Unlike other 3D printers, Branch Technology's robots do not have to build houses in class. Instead, their construction machines will create trellis, help shape and fix liquid and concrete foam when poured.

David Fuehrer, sales director of Branch, said that thanks to such construction methods, their homes will be 3-4 times more robust than current wooden houses. After completing the project, the Branch Technology Company is expected to donate this house to Chattanooga Community College to organize the class in it.
