3D printing technologies are constantly evolving and not only revolutionising production, but the products themselves. New, practically infinite possibilities emerge and lead to rethinking in almost every industry. 3D printing is also possible with concrete. G.tecz Engineering, a firm that specialises in cement-related, high-tech materials, has developed a nano-concrete for 3D industrial printers. It dispenses with the polymer-bound binders that are used until now.
