Title: Adaptable filament deposition system and method for freeform fabrication of three-dimensional objects

Abstract: An improved system for forming a three-dimensional object by filament deposition of forming materials includes a crucible for holding a reservoir of the filament forming material, an orifice disposed in the bottom of the crucible through which the forming material passes to form a flow of material filaments, and a flow control apparatus for controlling and selectively depositing the flow of material filaments on the substrate exclusively where required to form the three-dimensional object. In a preferred embodiment, the forming material is ejected from the crucible as a variable-diameter circular liquid jet, which cools to form variable-diameter filaments of semi-molten forming materials.
