3D printing, often referred to as Additive Manufacturing (AM) is the sequential layering of materials using computers to create three-dimensional shapes. The process appears relatively simple as a 3D digital model of the item is created. This is done either through computer aided design (CAD) or using a 3D scanner.

The printer reads the design and “prints” successive layers of a medium, either liquid, powder, or sheet material. These are joined together or fused to create the final product or item. While the 3d printing process can sometimes be slow, it can create almost any shape which is particularly useful for geometrically complex components.

The future of construction lies with robots getting down and dirty while implementing 3D printing technology. And now, 3D printing has found yet another purpose with the US military building barracks using a large 3D printer.
