3D printed concrete house – The advance of 3D printing and the techniques that revolve around it today lead to several sustainable construction options, which involve lower costs, time and new design possibilities. printed a concrete wall for the first time in 3D, demonstrating several advantages when using this technique in the field of construction, such as saving materials and tools, reduction of waste and CO2 emissions, speed in construction, decrease in work accidents, freedom to generate more complex and organic forms, etc.
3D printers different techniques and combinations of materials to achieve better results with a greater use of resources. For example, the contour crafting method is a process by which large scale structures can be created with a smooth surface finish. The end of the robotic arm where the material comes out has two flat palettes that allow to smooth the surfaces while the vertical walls are being created and the rails that are installed on the floor to the sides of the area to be constructed act as a guide for the bridge of the robotic arm in its route.
This development of houses printed in 3D, will be the first of its kind and scale. The construction of each house, will provide new keys and aspects to improve for the following, this project being a laboratory and kickoff to explore this tool in the field of construction and above all, the search for a solution to the problem of housing shortages that exists in different parts of the world.
