3 d printing: construction industry revolution

Recently, 3 d printing building domestic set off a squabble. A building and a 3 d printing office buildings, villas, appear in front of people, and foreign 3 d printing castle. These cases for 3 d printing shaping the image of a god of creation, with 3 d printing, the future human may no longer have to worry about the housing problem!

Recently, a new material by 3 d printing module villa in xi 'an, the builder within three hours completed the construction of the villa. It is understood that this non domestic debut 3 d printing villa, but still attracted many experts, investment Banks and foreign media attention.

3 d printing villa won praise

On the morning of July 17, a new material by 3 d printing module villa completed within 3 hours. The villa from the kitchen, bedroom, bathroom, living room lamp modules patchwork, the whole process only need a crane. It is understood that it weighs 100 kilograms per square meter, the cost price in 2500 yuan to 3500 yuan per square metre. Is 3 d printing villa, however it does not have to worry about the quality problem, it is said that this villa can resist magnitude 9 earthquake, building structure is fully filled with insulation, heat preservation effect of the building is also very good.

It is reported that the national increase material manufacturing development promotion project "has been basically completed and the upcoming, intelligent manufacturing has become the main direction of the ministry of industry and promote the combination of two, at present has drafted the relevant ministries and accelerate the intelligent manufacturing related Suggestions, increase material manufacture scale application is about to make substantive progress. Add material manufacturing technology, is the public commonly known as the "3 d printing".

State of 3 d printing development goals are: by 2017 the preliminary building material manufacturing technology innovation system, cultivating five to 10 annual output value of more than 500 million yuan, has strong research and development and the application ability of increasing material manufacturing enterprise; And across the country formed a batch of research and development and industrialization demonstration base and so on. On the policies and measures, the state will strengthen organization and leadership, strengthen the financial support, and support for 3 d printing enterprise in domestic and overseas listing, non-financial corporate debt financing tool, etc.

Although, the 3 d printing of the xi 'an villas, completing the whole 3 hours for most people to doubt, but according to the builder, the hardcover villa as long as can bag check in on the furniture. According to engineers, 90% of the villa building process is completed in the factory, that is, all the building blocks in a factory assembly line production, the scene is splicing, assembly and installation of these modules.

New materials into question

It is reported, make a house with 3 d printers, is the dream of architects around the world. In xi 'an before the 3 d villa, home also had to show 3 d printing construction as a whole. Among them, the bearing strength and durability of the "ink" and so on each index must conform to the standard. And the 3 d printing villa can cause a lot of attention, but also because of its new materials. Through the news about 3 d printing building, the 3 d printer is undoubtedly a major focus. At the same time, the "ink" raw material is also one of the reasons for 3 d printing building questioned.

3 d printing, experts said, "ink" the composition of the main ingredients are high quality cement and glass fiber. Extensive use of glass fiber and some countries ban building, because glass fiber affect the human respiratory system. At the same time, the high strength cement recycling also have trouble in the future.

According to introduction, villa has previously demonstrated are hollow wall built, one-time solve the bearing structure of the wall, so regardless of the Bridges, the theater, or hotel and residential buildings, and fastness are in accordance with the strength of the buildings and higher than the national construction industry standards. At the same time, 3 d printing building life cycle also can reach three hundred and fifty. 3 d printing wall strength 5 times that of ordinary cement. The building quality and lighter, theoretically the seismic effect will be better.

In addition, according to relevant industry researchers described, large 3 d printer is the same with the small printer. Nozzle ejected "ink" in "Z" glyph, layer upon layer overlay, base into the wall. Poured into the "ink" place, sand and gravel materials will be cured in one day. , between the wall and the wall can also be the same as the building blocks up and then become an organic whole repeatedly with reinforced concrete for the second print perfusion. The whole house, in addition to the steel structure, are printed.

The price cost savings of 50%

In the face of more and more fire villa 3 d printing technology, the personage inside course of study says, "low price" is the main attraction of a 3 d building. Traditional villa building up from construction time is about in the first half of the time, and 3 d printing module build villas from production to build only need 10 days of the time. And xi 'an the hardcover villa has six modules, weighs 100 kilograms per square meter, while the cost price 2500 yuan to 3500 yuan per square metre. Although housing construction time is short, but, because each module independently bearing can therefore magnitude 9 earthquake resistance. At the same time, the 3 d printing module structures, the villa is not in the market promotion, according to the builder, soon it will be for the civil service, an exclusive custom.

Reported that 3 d printing is the main benefit of building energy conservation, environmental protection, saving material, because 3 d printing building does not produce any dust, no construction waste is produced. For urban residents suffering from haze is good news. In addition, it also can turn, all kinds of construction waste, industrial waste, mine tailings can be used as raw material, and desert sand for them is just like a "gold", is a good raw material, can use local materials for sand-fixation wall, wall vertical greening, etc.

Not only that, the 3 d printing technology can also save construction materials from 30% to 60%, shorten the time limit for a project by 50% to 70%, save human from 50% to 80%. That is to say, through 3 d printing, can lower cost, faster time limit for a project built a house, building costs can save at least 50%.

Industry experts said, the use of 3 d printing, for real estate is going to be a subversive revolution. Future customers can customize household not only, still can customize their own house, printing all kinds of special-shaped components, a design to do a suite. Building in the community, on the basis of style coordinated also don't have the same.
