3D Printing - Future of Construction.

~ 3D printing (sometimes referred to as Additive Manufacturing (AM)) is the computer-controlled sequential layering of materials to create three-dimensional shapes. It is particularly useful for prototyping and for the manufacture of geometrically complex components.

3D printing may allow, faster and more accurate construction of complex or bespoke items as well as lowering labour costs and producing less waste. It might also enable construction to be undertaken in harsh or dangerous environments not suitable for a human workforce.

A 3D digital model of the item is created, either by computer-aided design (CAD) or using a 3D scanner. The printer then reads the design and lays down successive layers of printing medium (this can be a liquid, powder, or sheet material) which are joined or fused to create the item.  The world’s first 3D-printed commercial building, according to the Guinness World Records, was unveiled recently. The 2,600 sq ft building now houses the office of the Dubai Future Academy. It is 20 ft high, 120 ft long, and 40 ft wide.

One 3D printer took 17 days to print the basic building.
