One of those advantages is that the concrete printer has the ability to lay concrete only where it is needed constructively. Traditionally poured concrete is solid, and contains much more concrete than is needed constructively. More is being used, which is bad for CO2 emissions, because with producing cement a lot of this greenhouse gas is released.
Another advantage is freedom of form. With 3D concrete printing, very fine concrete structures are possible. In the traditional pouring of concrete, the formwork determines the shape of concrete. With concrete prints, builders will soon be able to make concrete details as small as a pea, and round, hollow or convex shapes. This makes concrete buildings and constructions with completely new forms possible.
Another new option is the printing of different types, qualities and colors of concrete, all in one integrated product. This means that a complete wall can be printed with all necessary functionalities. Such a wall has to be reinforced with fibers of wire that insulate, and on the outside must be kept dirt-repellent, and on the inside a layer that ensures pleasant acoustics. Further, it contains the required recesses and internal drainage pipes of waterproof concrete. This makes the construction process much faster.
Another advantage is the possibility to process individual wishes per individual customer. After all, a different version entails few costs.
The 3D printing of concrete creates the possibility to put sensors directly in the right place of the construction. Think of wireless sensors that measure temperature, sensor-controlled lighting, or that are used for security. These can be incorporated directly into the printing process, instead of afterwards. That saves time and money.
Concrete printing also has advantages for professionals. Traditional processing of concrete is heavy and demanding work. The vibrations of poured concrete and the braiding of the steel reinforcement nets is heavy. These activities are not necessary for 3D-printed concrete.
