The additive manufacturing process has achieved regulatory approval for use in residential construction. The process of making concrete printed homes uses very large 3D printers. These printer controls the characteristics and directions of the concrete flow as it enters or exits the extrusion pipe (nozzle). It is frequently used to modify or direct the printable concrete material. 

The concrete material is laid down layer by layer to fabricate the building element needed for the printed concrete construction. Although the process is sometimes referred to as concrete 3D printing, the builder might not always use concrete in the strictest sense. That’s because traditional concrete is probably not the best choice for 3D printing: this material would clog the printer’s nozzle and wouldn’t properly adhere to the layers previously extruded in the process. Many materials used to create concrete printed homes are unique. Some of the materials are patented. That’s why selecting the right materials in building the 3D printed house is as important as the design and printer.
