MX3D, a research and development startup company, will use robots to 3D print a pedestrian bridge across one of Amsterdam’s canals. The versatile six-axis robotic arms will ‘draw’ steel structures in 3D, starting from one side of the canal and building across until it reaches the other end. The robot will also print its own support, which allows it to work autonomously. The location of the bridge will be announced soon and construction is set to commence in 2017. — iflscience.com
