Concrete 3D printer

Materials & Processes

Imprimante 3D béton

The concrete 3D printer is of the Cartesian type. It is fed by a concrete pump into which the cementitious “ink”—prepared beforehand in a concrete mixer—is poured. This ink then flows through a hose to the printer’s print nozzle. The printer is controlled by a computer system into which the file defining the shape of the part to be printed is imported. This system allows for the adjustment of both the printer’s speed and the pump’s feed rate to deposit the desired print bead.

The printed parts can measure 70 cm at the base and 60 cm in height.
