Concrete 3D printing brings faster, more cost-effective and sustainable methods to a range of construction applications, proponents of the technology contend. Printing involves extruding a specially formulated concrete or mortar mix layer by layer to create complex structures without the need for traditional molds or formwork. As 3D printing practice gains momentum, concrete producers should look at how they might…
