Prototyping technology has evolved significantly due to the introduction of 3D Printers.  3D Printers can create a 3D model of a product or an actual product.  It can do this in a matter of hours or minutes depending on the complexity of the part and the capability of the 3D Printer.

When 3D Printers were first introduced the prices were prohibitively high for small businesses and startups but, prices have significantly been reduced to the point where anyone can buy one and utilize it in their homes.  3D Printer prices are approaching those of a regular printer.
