Over the past few years, designers and construction companies have experimented with using large, 3D printers to build homes, offices and other structures.
- The old thing: "Printing" building blocks and parts of homes, which are then assembled on-site.
- The new thing: Using 3D printers to print an entire building on site.
Pros: 3D printing would help eliminate waste in construction and can use recycled materials as building materials. Homes eventually could be easily personalized, and could provide cheap, safe housing in the wake of natural disasters.
Cons: There's still a long way to go with 3D technology and building printers that are large enough to build these structures. It's difficult to meet the intricacies of building code requirements while programming the printers, and most homes that have been built are tiny and not particularly stylish.
