Special statement
Do you want to live in a house built with 3D printing? Recently, several buildings using 3D printing technology have appeared in suzhou. The construction includes a building area of about 1000 square meters of villas, residential buildings in a 5 layer and a simple exhibition hall, etc., building wall by large 3 d printers print, this house spent printers, the time of day.
Living in such a house is just the beginning, the future, "printing" will become a way of life. You tomorrow want to ask a guest to home, for example, found that the glass is not at home, at this time, you can rely on their own preferences through software modeling, then open the 3 d printers in the home, after a period of time, the printer can give you private ordering such a cup. We'll print out what we want.

3D printed house, do you want to live?
Where is god in 3D printing?
The first step is to tell the difference between 3D printing and printer printing. Ordinary printer with ink and paper, and ultimately print out the computer design of planar objects, the process contains two links, one is the design, the second is the print materials according to the design principle, is printing.
These two steps also apply to 3D printing. 3 d printing technology is three-dimensional design, and the printer "swallow" into the belly of the raw materials into metals, ceramics, plastics, genuine materials such as sand, after connect with computer, printer with computer control can be the "print material, one layer upon layer overlay" eventually "spitting out" is the real items. In layman's terms, as long as the raw material is right and the design goes through, 3D printers can print a lot of real items like houses, food, food, cheap prosthetics and so on.
If you look at it in detail, here are two steps:
1, 3 d design: first, through the computer aided design (CAD)/computer animation modeling software modeling, then build the 3 d model of "split" into layered cross section, thereby guiding the printer to print one by one.
2, printing process: printer by reading the cross section information in the file, use material to the section step by step to print it out, then each layer section together in a variety of ways to create an entity.
Here is a real combat analysis. How is the suzhou villa printed?
Obviously, such a big guy, obviously not only the 3D printer's contribution, the role of the printer, is the house parts processing. According to media reports, the printing of the building is to build the internal steel structure first, then the 3D printer prints out the building components and then assembles them. The most amazing thing is that such a building can be completed only by three workers, which would be a shock to the ancient emperors in ancient times.
The biggest contribution of a 3D printer, then, is to print out the wall. According to the report, a layer of wall brick wall outside, inside is the horizontal layers of cement mixture like noodles up the thread of the wall, each "noodles" are closely integrated, very solid wall surface. The "ink" materials for printing buildings are mainly construction waste, industrial waste and mine tailings.
You can imagine printing such a big guy that the printer must be big. The data show that the "printer" is 6.6 meters high, 10 meters wide and 32 meters long, with a floor area of a basketball court and a height of three stories. The printing process is a huge shower nozzle jet ink, just like the mounting of a wall of a wall of a wall, the scene is a little exciting! The feeling of blowing up the sky! After that, the wall and the wall can also build up like building blocks, and then use reinforced concrete to make a second "printing" perfusion. Such a $80 million villa, with 3D printing technology, costs just $1 million.
3D printing spread to all corners
More and more, the fact that 3D printers are no longer an exclusive machine for designers and scientists is closely linked to the lives of every ordinary human being. It can make small cakes such as cakes and cookies, and can design fashion clothes such as canvas shoes and high heels, and build cars and houses. You can enjoy the joy of this new technology in every bit of your life.
In the field of production, 3 d printing antenna has been far beyond the traditional manufacturing industry, extends to the military, medical and other fields, and even produce some of the new business model, and it can be said that the many industries because of the existence of the technology, and even subversion.
Many industries are constantly showing vitality, and some industries are dying out. If you are a teacher, if you take 3 d printing technology to produce small shark model come to the classroom, the students in this class will definitely bring you deep impression, if your students through the 3 d printing of autonomous design, and take the finished product to the classroom to share, he will be in a deep knowledge memory. This is how smart education, one of the new 3D printed blue seas.
Entrepreneurs are studying 3D printing technology from various aspects, from printing, scanning, manufacturing and content sharing. In the future, various functional materials are entering the market. As more advanced printing technology goes into use, more desktop machines will be available this year. There are also many businesses that aim to develop faster and cheaper industrial equipment. There are more 3D printers dedicated to the development of public consumption.
"3D printing is still only in the early stages of development," said Kevin kelly, the Internet's "prophecy". "many companies can only print something simple." Based on the profound traditional manufacturing background, China will become a leader in the new round of 3D printing technology.
Why doesn't gou favor 3D printing?
3D printing seems to be a promising future, and the media has described the 3D printing technology as the third industrial revolution. But guo taiming, the maker of the company and chairman of hon hai, takes the opposite view. "If it really is (useful), then I will write the word 'guo'," gou said at a planar display exhibition, according to Taiwan's lianhe evening news.
What's the basis for that? Mr Gou said hon hai had been using 3D printing technology 30 years ago because the technology could not be used for commercial purposes and was not commercially viable. He USES 3D printed calls as an example to show that this can be made, but can only be seen and cannot be used. Therefore, 3D printed goods cannot be added to electronic components and cannot be produced by electronic products.
These words, indeed, mark some of the pain points of 3D printing. At present, the big problem with 3D printing is that it can't make parts for electronic systems, which severely limit the scope of 3D printing. Because chip involves different kinds of material, 3 d printing devices can make a molding single material products, but products that are printed separately from the only parts of different materials, in fact its convenience and advantage has been compromised.
In addition, 3D printing is too expensive to meet the required intensity. For example, using 3D printing technology to make car engines, using very expensive machines and expensive materials, can achieve the required intensity.
At the same time, 3D printing is very limited. Industry insiders believe that the technology is still limited to the pilot stage, and the current application area is not broad enough. The extension of the material determines the capability boundary of the 3D printer. The initial application of 3D printing was limited to sample production. Some precision instruments or high-cost products can be quickly designed with 3D printing to save time and material costs. The long term for 3D printing is to make parts that are so complex that they are difficult to process.
However, if it is used to make parts that are not difficult to process, the efficiency is significantly lower than that of traditional machine tools. In modern manufacturing, most of the parts are easy to process, can be standardized, and can be made many times per minute with machine tools, which is much faster than 3D printing. So for now, the impact of 3D printing on traditional manufacturing is still very limited.
