Traditionally placed concrete has long been the most economic method of construction. If 3D concrete printing is to compete with this tried and trusted solution, then structures need to be printed efficiently. This is precisely what Sika’s technology is designed to achieve. Frank Höfflin, Chief Technology Officer at Sika: “We have now achieved our ambition. With our technology, it is possible to print concrete so rapidly, inexpensively, and precisely that it can be used on construction sites.”
