When it comes to printing technology, no one should be unfamiliar with it. For example, printers, just send the document to the printer, no matter how many words can be quickly and neatly printed out, but the printer can only print text or pictures and other two-dimensional information.

If I want to print a real house now, can I?

The answer is: yes!

Times have evolved and so has technology. Printing technology has evolved from 2D to 3D, let us understand this technology!

At present, there is no clear classification standard for 3D printers, but we can be based on the market positioning of the device, it is simply divided into three categories: personal-grade, professional-grade, industrial-grade.

1. Personal-grade 3D printers: most domestic 3D printers are based on foreign open-source technology extension, as a result of the use of open-source technology, the cost of technology has been greatly compressed, so the selling price of 3,000 to 10,000 ranging from foreign imported brands of personal 3D printers priced at 20,000-40,000 between. Equipment printing materials are ABS plastic or PLA plastic-based, mainly to meet the requirements of individual users in the use of life, so the technical indicators are not outstanding, the advantage is that the volume is small, cost-effective.

2. Professional-grade 3D printers: available molding technology and consumables than personal 3D printers are much richer, more advanced equipment structure and technical principles of automation is higher, the function of the software and the stability of the equipment is also beyond the reach of personal 3D printers. The price range of this type of equipment is more than 100,000 to millions of yuan.

3. Industrial-grade 3D printers: industrial-grade equipment in addition to meet the special characteristics of the material above, the manufacture of large-sized objects and other requirements, the more critical is the need to meet the standards of special applications, because this type of equipment manufactured objects are directly applied. Since many of these devices are customized according to demand, it is difficult to estimate the price.

Full-size printing. The limitations of this direction are more obvious, the bigger the building the bigger the 3D printer needed, the bigger the 3D printer, the worse the printing accuracy and speed. So at this stage of single printing is mainly to solve some basic problems of 3D printing houses, such as materials, control, accuracy, etc..

Segmented assembly printing. That is, the modularization of the building, each piece is printed in the factory and finally assembled on site. This way is very similar to our current assembled building, where the building modules are made in the factory and finally assembled on site. Only this method uses 3D printed modules, and the assembly building modules are made in the traditional way.

Swarm robot collective printing assembly. This is a group of 3D printers like bees to perform tasks together (such as printing a whole house), with full-size printing compared to the size of the group of 3D printers has nothing to do with the size of the building, and at the same time the printer's intelligence requirements can also be greatly reduced.
