3D Architecture Solution
Application profile

Contour forming technology (commonly known as "3D printing building technology") is a rapid construction system developed by the rapid prototyping laboratory of the university of southern California in the United States, which is automatically controlled by the computer. It can directly build the building model designed in the computer into the actual building in a short time at a much lower cost than the traditional process.

3D printing is undoubtedly a hot topic. 3D printed cars, 3D printed hearts and so on all appear on the front pages of various media. Now, 3D building printers are coming.

Before "printing" a house, two rails need to be built around the foundation for the printer to move around. When working, the 3D printer will pour concrete into the house layer by layer and carry building materials such as hanging beams on the ground to the building frame by itself. In less than a day, the whole structure of the house can be completed, and the rest is left to the decoration team.


NASA, in collaboration with the university of southern California, has developed a "contour process" 3D printing technology that can produce a two-story house of about 232 square meters in 24 hours. Saving time and money on construction, the technology allows humans to quickly and mass-produce "alien houses" after colonizing the moon or Mars.

Print order:

1. A set of 3d printing construction equipment

2. Use machinery to sketch an overall outline and line on the construction site

3. When building the wall, the robot will automatically leave the position of the door and the window according to the plan

4. Cover the ceiling of the first floor and then water the second floor on top

5. Finally complete the details of roof, wall and external structure

Low cost, saving money and materials, faster and more environmentally friendly

According to introducing, in order to save construction materials, "technological" robot printed wall is hollow, though the lighter, but their intensity coefficient of about 10000 psi (that is, able to withstand 10000 pounds per square inch pressure) - far more than the traditional the walls of the building, and save 20% to 25% from 25% to 30% of the funds and materials.

The biggest saving of "contour process" is still manpower. Through the use of 3D printer, "contour process" will save 45% to 55% of labor, and correspondingly use less energy and emit less carbon dioxide, which not only greatly reduces the cost, but also greatly improves the speed.

Beautiful appearance, undulating exterior wall, more beautiful and more environmental protection

Although there are still some shortcomings in the "contour process" technology, its birth means that there will be many new types of work in this field. At present, the project has received the attention of many construction institutions and companies.

Professor horshnevis stressed that the new technology could also allow building components to be shaped as needed, rather than as traditional straight lines. In addition, it can also play a role in disaster reconstruction, slum reconstruction.

Professor horshnevis said that by 2050, 3D printing of houses will have become a mature technology, and robustness will not be the primary concern. Besides, due to its low cost, it is not necessary to change it in a few years.

Space dream, local materials, mass printing of alien houses

It is worth noting that the "contour craft" technology is not only limited to the use of earth, but also can be used in outer space. In 2050, the United Nations estimates that global population will reach an unprecedented 9.6 billion people, the earth's living space will be more crowded, the Dutch nonprofit organization "Mars" number one pick out 1058 people from 200000 applicants, immigration to Mars training, is expected to be selected 24 immigrants, in 2024, is divided into six pilot in order to live on Mars. If humans are to migrate to other planets in the future, housing will be the top priority.

Professor horshnevis said that if humans were to build habitats on the moon in the future, 90 percent of the building materials would be expected to come from lunar soil, while the rest would need to be transported from earth to the moon by spacecraft. As the cutting-edge technology becomes more sophisticated, space migrants are expected to lead more comfortable lives, thanks to the ability to build habitable buildings in batches faster and more environmentally friendly.
