Concrete printing

Architectural design freedom lies in the detail

Compared to other methods, additive manufacturing processes are associated with a large number of benefits that become particularly apparent when producing free-form elements. 3D powder printing enables the manufacture of slender, custom-made structures with optimized topology without requiring additional auxiliary or support systems. Manufacturing such structures would not be possible with conventional formwork and contour crafting, i.e. one of the other common 3D printing methods, when it comes to overhangs or cavities.
