Swiss researchers from ETH Zurich recently won the Swiss Technology Award for their innovation in reverse engineering with concrete. Using a matrix of woven filament created with 3D printed robotic arms, the wet concrete is held in place until it dries, forming into a strong structure that be created fast and affordably. They will be testing it out further in 2017 as they create a concrete wall structure for the NEST building in Dübendorf. Read more at 3DPrint.com: https://3dprint.com/157296/swiss-tec...d-3d-printing/
