Researchers at Nanyang Technological University, Singapore have developed a technology for synchronized, robotic three-dimensional (3D) printing of concrete.
Two robots concurrently 3D-printed a concrete structure measuring 1.86 meters x 0.46 meters x 0.13 meters in eight minutes, using a specially formulated liquid cement compound.
The process begins with a computer mapping out the design to be printed and assigning a specific printing stage to one robot, using a special algorithm to make sure each robot arm would not hit another while printing.
Said Chua Chee Kai of the Singapore Centre for 3D Printing, "This multiple robot printing project is highly interdisciplinary, requiring roboticists to work with materials scientists to make printable concrete. To achieve the end result of a strong concrete structure, we had to combine their expertise with mechanical engineers and civil engineering experts."
