Building anything has become accelerated due to technology. And the most disruptive and notable of late is 3d Printing. It's used most commonly to prototype products and industrial design but it's also shaving massive amounts of time off of Architectural Mock Ups and Scale Models.

Injection Molding Companies from China to Los Angeles are finding that rapidly prototyping in 3d is also increasing creative conceptualization as feedback is immediate. So are architects. By building prototypes and scale models of entire structures, architects are finding rapid iteration dramatically increases their responsiveness to versioning. For example, by spraying water on a scale model of a building, a structural engineer and architect can both see hydrodynamics in action.

Not only is prototyping benefiting from 3d Printing, Injection Molding in China or Los Angeles is also being used to produce prefab homes and office building components.
