The world's biggest 3D printer can a make a house in under 80 hours

The University of Maine just unveiled the world's largest polymer 3D printer. The new printer, named Factory of the Future 1.0 (FoF 1.0), can print objects as large as 96 feet long by 32 feet wide by 18 feet high. It's also quite speedy, relatively speaking, as it can print up to 500 pounds per hour. It can dynamically switch between printing techniques to suit different aspects of complex jobs. The printer can flip between large-scale additive manufacturing, subtractive manufacturing, continuous tape layup and robot arm operations.
