Can a 3D printer that produces cement walls crack the code on affordable housing? Imagine a giant printer that squeezes out row after row of cement as it traces the footprint of the home, building out all the walls, both internal and external. A two-person crew is there to watch and troubleshoots errors as the skeleton of the structure goes up over a period of eight to nine days. Then the machine backfill walls, as the crew installs anchor bolts and assembles pre-built timber pieces for the roof. When the structure is complete, finishers come in to finish walls, paint, apply siding, and roof, while a third crew installs fixtures and appliances. The method is said to be stronger and more durable than wood-frame construction house at half the building cost.
