3D PRINTING OF CONCRETE STRUCTURES

3D PRINTING OF CONCRETE STRUCTURES IV development, but does strongly increase the total construction time. The choice of printing environment clearly influences the end result as well, as the low temperatures of in-situ printing result in much slower strength development compared to controlled, prefab printing.
