This is one of the largest 3D printing jobs done by an automated system, and it has been done at the highest speed recorded so far, according to a study published in Science Robotics.
Specifically, they have 'printed' a structure 4.7 meters long and 3.7 meters high in less than 14 hours.
Construction workers robot
A team of engineers from the Massachusetts Institute of Technology (MIT) aims to revolutionize the architectural industry through robotics with this machine that runs on batteries and solar energy, and is equipped with a robotic arm whose precision exceeds that of traditional construction systems.
The structure was constructed with insulating foam, but the robot is able to use other materials such as cement, rubble or even ice, if it is in its environment. You can see it in action in the following video:
