Into the Fog - out latest experiment toward printing perfection
Vertico has been running cracking tests on a recent 3D print, and one setup produced a striking side effect: fog. The experiment looks at how different curing conditions affect cracking in printed concrete.
How the fog setup works
Water vapor is created over the print bed to keep the humidity high. The difference between the print temperature and the air temperature drives a convection whirlwind around the object.
That airflow keeps the surface of the print moist and traps water inside the concrete, which prevents shrinkage cracking. The moisture hanging around the print gives the fog-like effect seen in the video.
Part of a wider test program
The fog setup is one of several conditions we are testing to understand cracking in 3D concrete printing. It sits alongside other material tests, such as the bone test, where we push our material to failure.
More insights from the testing process will follow.
