Robotic exhalation is a novel digital fabrication methodology that uses digitally controlled
pulses of compressed air to form concrete panels that can vary in porosity and
In the robotic exhalation workflow, a pen
plotter-turned-exhalation machine continually blows compressed air onto
concrete immediately after it has been poured into an open face mold. The
constant air flow repeatedly forms the wet concrete until the mixture sets. The designer specifies where the machine exhales, for what
duration, and with what force, as well as the rheology of the concrete.
