3D Printer 

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

So has been started

3D printing is sometimes hailed as a revolution for architecture and construction. In fact is much faster and cheaper than conventional building, and that it has a smaller environmental footprint. But so far, machine-printed buildings have not materialized in significant numbers. Most examples are one-offs and are not fully habitable. The technology is hard to reconcile with building codes, and large-scale printers are scarce and expensive.

However, robotic architecture is still maturing. Recent examples include an office space in Copenhagen (2017) and a micro-home in Amsterdam (2016). Last March, an Austin startup named Icon debuted a tiny 3D-printed house, built in less than 48 hours, at South by Southwest.
