Method for freeform fabrication of a three-dimensional object

A method for forming a three-dimensional object by deposition of one or more molten forming materials on a substrate, the method comprising the steps of:

• loading a reservoir of said one or more forming materials in one or more containers;
• maintaining said one or more forming materials in a molten state in said one or more containers;
• ejecting said one or more molten forming materials from said one or more containers and through one or more adjustable planar nozzles;
• adjusting the size of said adjustable planar nozzles to form variable size planar jets of said one or more molten forming materials flowing towards said substrate, said planar jets forming layers of said one or more molten forming materials to be deposited on said substrate;
• positioning said substrate beneath said planar jets flowing towards said substrate;
• and
• depositing said one or more forming materials in layers on said substrate to form said three-dimensional object.
