The first 3D printers seemed like a miracle. Now they are used everywhere: in medicine, in industry, in construction. Thanks to improved 3D printing technology and the use of a special grade of cement, it has become possible to create both small objects and large ones. Using a printer, you can create a flowerpot, shop, or building blocks. But you can just as easily print a full-size building structure. After all, the principle remains the same, the only difference is in scale.
A construction 3D printer works just like any other, that is, it uses extrusion technology. But in this case, we are not talking about the already familiar polymers - plastic and silicone. The printer uses special building materials in its work. They are squeezed out of the nozzles layer by layer, gradually forming the structure specified by the program.
Of course, we are not talking about any high resolution. But this does not matter, because the concrete structure in any case will undergo further processing, including decorative. The advantages of this method are:
- Significant reduction in production costs,
- Reduction of the time required for the construction of the object;
- Minimization of the risk of occupational injuries;
- High precision of structures;
- The ability to create original concrete structures without formwork.
The construction 3D printer uses multi-layer printing technology. The structures created in this way are durable and smooth.
The printer prints everything from walls and floors to stairs and decorative items. The only exception is the roof. The roof must be erected in the traditional way. Naturally, all external and internal decoration, laying of communications are also carried out by specialists manually.
The power of modern technology is not unlimited. There are no printers capable of constructing a multi-story building without any human intervention. But it is quite possible to print a two-story house with an area of up to 120 m2. For example, the S-1160 format printers are quite capable of coping with this task. Such devices cannot be called compact - their dimensions are 12x12 m. Placed on a construction site, they are able to print a house in one installation.
The standard building volume of the printer is 12 m3 of concrete. If necessary, these parameters can be increased to 36 m3.
It should be noted that printing from A to Z is extremely rare. Usually, construction work involves human participation. By combining 3D printing and classical techniques, complex beautiful buildings can be erected. Moreover, all labor-consuming elements requiring the creation of special patterns are performed by the machine.
Since the printer does everything in full accordance with the program, the design fully complies with the specified parameters. The human factor is completely excluded, therefore, subsequent adjustment of the structure and elimination of defects are not needed. There are no deviations in corners, cracks, windows, and doorways that fully comply with the standards.
These printers are purely professional equipment. To use it, you need the appropriate qualifications and special building materials. The equipment is designed for continuous operation and requires minimal maintenance. It is only necessary to lubricate the linear guides from time to time. The motor gearboxes and hardware are maintenance-free.
