3D Concrete Printing Moves From Demo to Job Site This February

February is not usually the month when contractors experiment with new building methods. Cold weather tends to push teams toward caution. This year, though, several crews leaned into technology instead of backing away from it.

On a small municipal building project completed in February, a contractor used large-scale 3D concrete printing to form structural walls directly onsite. What began as a demonstration technology a few years ago is starting to look more practical, especially for low-rise structures and utility buildings.
