Abstract: According to the National Bureau of Statistics data show that in recent years, China's housing new start area overall growth trend, 2021 housing new start area of 1.989 billion square meters, 2023 in the first two years of a slight decline, is expected this year China's housing new start area will rise to 2.315 billion square meters. With the development of urbanization, the traditional construction industry has become increasingly inefficient, high energy consumption and high pollution, and transformation and upgrading are on the string. Intelligent 3D printing buildings are on the rise in China with their green, efficient and new technology construction methods. With the progress of technology, the use of 3D concrete printing technology of new building and green building materials has been deeply concerned by the industry.

1 Introduction
  Today, China is facing a new round of scientific and technological revolution and industrial change, intelligent manufacturing mode characterized by the deep integration of information technology and manufacturing technology is leading the profound change of the entire manufacturing industry, 3D printing as a representative of the subversive technology of the manufacturing industry is the transformation of the industry to intelligent manufacturing, increasingly attracting people's attention.

  In recent years, Wenzhou Wengong Construction Machinery Co., Ltd. has actively promoted the application of 3D printing construction technology in China in the form of strategic cooperation with Shanghai Tongji University, Xi 'an Jiaotong University, HIT and other institutions of higher learning.

  The practice of many well-known domestic intelligent technology development enterprises such as "China Building Technology Center", "Ying Chuang", "China Construction Eight Bureau", "Ogmeirui" and "Dajie", which apply warm 3D concrete printing pump, proves that not only China's 3D building technology is on the rise, but also increasingly mature, and the development of 3D printing buildings is imperative.

2 Application Significance
  2.1 3D concrete printing pump developed by thermal manufacturing combined with intelligent control, accurate limit, ink acceptance ability, provides reliable technical conditions for 3D printing buildings, and plays a certain role in boosting the development of 3D building technology in China into the fast lane.
  JP10ZN 3D concrete printing pump with lithium battery as power supply, low voltage micro electric power, matching charging pile, the machine came out to change China's construction to get rid of the traditional masonry technology will play a positive role.

  JP10ZN has advanced technology, rapid response to command execution, accurate positioning, no offset superposition, fast forming, and extended range of activity.
  2.2 In recent years,3D printed buildings have become a hot topic in the construction industry. 3D printing technology for additive manufacturing technology, with the aid of the computer, the three-dimensional entity manufacturing into a two-dimensional layer of accumulation and along the forming direction of the continuous stacking, and finally create a three-dimensional entity, with short construction period, high efficiency, low comprehensive cost and many advantages. The use of 3D printing technology of new green building materials, by the industry's attention.

3 Working Principle
  3.1 3D printers complete 3D digital modeling based on traditional structural drawings, and introduce intelligent technology in equipment control and software development to make 3D printing more efficient and accurate. On the basis of automation, the use of computer vision recognition assistance system and a variety of sensors to make the printing process more intelligent, through visual recognition optimization, to ensure that 3D printed buildings can be efficient construction, consistent appearance, accurate size.
  3.2 Through the automatic positioning system, the position of the steel mesh and other decorative components is accurately positioned to reduce manual intervention and reduce errors. In addition, VR virtual reality technology is also used to allow customers to experience personalized customized buildings, changing the real estate "production and sales" model.

4 Produce effects
  Relying on the automation and intelligence of 3D printing technology, subvert traditional construction methods and set off an architectural revolution:

  4.1 Greatly reduce material and labor costs, through mechanized intelligent operation to replace tedious manual operation, compared with traditional construction methods, no construction waste, can save building materials 30%-60%, save labor 50%-80%. 3D printing technology can also reserve pipeline doors and Windows on the basis of retaining the original steel beam and column structure system, realize the integration of internal and external decoration and complete printing, shorten the construction period by 50% to 70%, and greatly reduce the construction production cost.

  4.2 Ensure the construction quality as much as possible on time. Fully automated production mode, abandon the traditional wet operation, avoid manual error, high quality and efficient.
  4.3 Facilitate the construction of special-shaped buildings. The traditional construction method is to use bricks, and the overall shape of the house is limited. 3D printing can make the building shape as desired, as long as the shape and pattern are designed in advance, and the wall can be assembled after printing.
5 Conclusion
  3D printing buildings not only technically realizes the intelligence, saving, green and low labor intensity of the production link, but also maximizes the use of building renewable resources and realizes the recycling of building materials. In order to vigorously promote the industrialization and intelligence of new buildings and promote the sustainable and healthy development of the construction industry, it has played an important leading role.
  At present, Wengong is adapting to the progress of The Times, taking advantage of the great opportunity of the rapid development of the intelligent industry, adhering to the theme of innovation, and striving to make great efforts in the field of 3D printing construction technology and strive for new achievements.
