Fast Complexity

Fast Complexity is an automated solution that combines the fabrication speed of concrete 3D printing and the geometric precision of reusable 3D printed formwork. We demonstrated this method with a highly optimised post-tensioned structural slab prototype.

To make this possible, we developed an innovative process that allows us to dynamically control the setting rate of the 3D printed concrete. This digital control over material properties means we can extrude a fluid concrete that emulates the complex surface of the formwork perfectly, and a fast setting concrete that does not need any additional formwork for the upper structure.
